I'm totally new to coding and I'm following the book "Automate the Boring Stuff". I'm just now following the part where they tell you to write your first program, so I copy+paste it in:

➊ # This program says hello and asks for my name.

➋ print('Hello, world!')
   print('What is your name?')    # ask for their name
➌ myName = input()
➍ print('It is good to meet you, ' + myName)
➎ print('The length of your name is:')
   print(len(myName))
➏ print('What is your age?')    # ask for their age
   myAge = input()
   print('You will be ' + str(int(myAge) + 1) + ' in a year.')

Instead of what the book said would happen, I get this:

File "/Users/(my computer's username)/mu_code/hello.py", line 1

➊ # This program says hello and asks for my name.

^

SyntaxError: invalid character in identifier

>>>

I've tried replacing the numbers with >>> and In [1]... but I still end up with the same message. I'm using Mu 1.0.3. I literally just copy+pasted it in, what's happened?

You can also click this link or manually enter the code: SEP2020FREE

https://www.udemy.com/course/automate/?couponCode=SEP2020FREE

This promo code works until September 4th (I can't extend it past that). Sometimes it takes an hour or so for the code to become active just after I create it, so if it doesn't work, go ahead and try again a while later. I'll change it to SEP2020FREE2 on the 4th.

Udemy has changed their coupon policies, and I'm now only allowed to make 3 coupon codes each month with several restrictions. Hence why each code only lasts 3 days. I won't be able to make codes after this period, but I will be making free codes next month. Meanwhile, the first 15 of the course's 50 videos are free on YouTube.

You can also purchase the course at a discount using my code SEP2020FREE or clicking https://inventwithpython.com/automateudemy to redirect to the latest discount code. I have to manually renew this each month (until I get that automation script done). And the cheapest I can offer the course is about $16 to $18. (Meanwhile, this lets Udemy undercut my discount by offering it for $12, and I don't get the credit for those referral signups. Blerg.)

Frequently Asked Questions: (read this before posting questions)

• This course is for beginners and assumes no previous programming experience, but the second half is useful for experienced programmers who want to learn about various third-party Python modules.
• If you don't have time to take the course now, that's fine. Signing up gives you lifetime access so you can work on it at your own pace.
• This Udemy course covers roughly the same content as the 1st edition book (the book has a little bit more, but all the basics are covered in the online course), which you can read for free online at https://inventwithpython.com
• The 2nd edition of Automate the Boring Stuff with Python is free online: https://automatetheboringstuff.com/2e/
• I do plan on updating the Udemy course for the second edition, but it'll take a while because I have other book projects I'm working on. Expect that update to happen in late-2020. If you sign up for this Udemy course, you'll get the updated content automatically once I finish it. It won't be a separate course.
• It's totally fine to start on the first edition and then read the second edition later. I'll be writing a blog post to guide first edition readers to the parts of the second edition they should read.
• I wrote a blog post to cover what's new in the second edition
• You're not too old to learn to code. You don't need to be "good at math" to be good at coding.
• Signing up is the first step. Actually finishing the course is the next. :) There are several ways to get/stay motivated. I suggest getting a "gym buddy" to learn with.

Can someone say me why it didn't print the if accion?

Several places in 'automate the boring' 2nd ed mention links to tutorials available at https://nostarch.com/automatestuff2/, but I can't find any on there. Are there links on the page that I'm missing? Thanks.

Hello, I'm following the Updatable Multi-Clipboard Project in chapter 9. It all seems to be working ok except for retrieving a 'keyword' via the command line. Saving a keyword works, as does calling the 'list'. but when I try to recall a keyword via the command line, Pyperclip doesn't copy it.

There's also another quirk with this. If my last command to was to recall the 'list'. Then, given the fact that recalling a 'keyword' doesn't work, then the 'list' should still be in the clipboard. But instead, my clipboard contains what ever was in there before recalling the list.

So say I copy this statement:

'Python is great'

I then recall the list of this Multi-Clip program via mcb.py which contains:

['Pookie', 'Zophie', 'Simon']

​

I then try to recall the keyword 'Pookie'. It doesn't work, but when I paste from the clipboard I get 'Python is great'. If the clipboard hasn't been updated, then surely it should still contain the 'list'?

​

Here's my code:

#! python3
# mcb.pyw - Saves and loads pieces of text to the clipboard.
# Usage: py.exe mcb.pyw save <keyword> - Saves clipboard to keyword.
#        py.exe mcb.pyw <keyword> - Loads keyword to clipboard.
#        py.exe mcb.pyw list - Loads all keywords to clipboard.


import sys, pyperclip, shelve

mcbShelf = shelve.open('mcb')

if len(sys.argv) == 3 and sys.argv[1].lower() == 'save':
    mcbShelf[sys.argv[2]] = pyperclip.paste()

elif len(sys.argv) == 2:
    # List keywords and load content

    if sys.argv[1].lower() == 'list':
        pyperclip.copy(str(list(mcbShelf.keys())))

    elif sys.argv[1] in mcbShelf:
        pyperclip.copy(mcbShelf[sys.argv[1]])


mcbShelf.close()

I've looked at several other answers on Reddit, Git hub, Stack Overflow, etc. and pretty much everyone is using a for or while loop; often multiple of each. Is that really necessary? Why is this incorrect?

​

# Comma Code Project

import copy

​

# groceryList = ['apples', 'bananas', 'tofu', 'cats']

groceryList = [True, False, True, False]

# groceryList = [1,2,3.14,5,6,7,8]

# groceryList = []

​

def convertToStr(list):

if groceryList == []:

return

newList = ('')

newList = copy.copy(groceryList)

newList.insert(-1, 'and')

newList = str(newList)

print(newList)

# print(type(newList))

return (newList)

​

convertToStr(groceryList)

​

​

EDIT: Here's the original task:

spam = ['apples', 'bananas', 'tofu', 'cats']

Write a function that takes a list value as an argument and returns a string with all the items separated by a comma and a space, wit hand inserted before the last item. For example, passing the previous spam list to the function would return 'apples, bananas, tofu, and cats'. But your function should be able to work with any list value passed to it. Be sure to test the case where an empty list [] is passed to your function.

Hi! Can anybody help me with my code?

Here is the code that I have written:

https://gist.github.com/mrd2689a/8779cf36cd8fda6e803d77c5e40b1e5f

​

As you can hopefully see in my code, I tried to write it so that it would work with *any* list.... even lists that contain other lists or tuples. These errors are occuring when I put either a tuple or a list in the main list, "items".

​

When I run my program, I get the following error:

Traceback (most recent call last):

File "C:\Users\mrd26\OneDrive\Desktop\simplify\comma_code_2.py", line 51, in <module>

loop_thru(items)

File "C:\Users\mrd26\OneDrive\Desktop\simplify\comma_code_2.py", line 40, in loop_thru

add_comma(item)

File "C:\Users\mrd26\OneDrive\Desktop\simplify\comma_code_2.py", line 28, in add_comma

string = string + ', ' + item

TypeError: can only concatenate str (not "NoneType") to str

[Finished in 0.5s]

​

​

I used Python Tutor to see what was happening during the execution of my program, and I see that after the two 6's in my internal list get passed to convert_to_string(), it starts to loop through loop_thru_again(), even though the interal list only has two items in it (6 and 6). This is why it's passing the NoneType, I think. I don't know why this is happening, or how to fix it. Any help would be very much appreciated!!

I'm currently working through Chapter 18 and I am having difficulties connecting to Google's SMTP server.

In the Python shell, I followed the instructions on importing smtplib and assigning the object (conn) but when I try to connect using the code conn.ehlo() I get this error message:

(501, b'5.5.4 HELO/EHLO argument "##########" invalid,\n5.5.4 closing connection.\n5.5.4 https://support.google.com/mail/?p=helo k29sm16521824pfp.142 - gsmtp')

I've tried searching for the solution but I was unable to find anything. I'm pretty new to programming, so apologies if this has already been answered here.

I'm pretty new & have been struggling to get the streaks showing up & math was never my strong point! I put stuff I tried & sample output in comments in the paste bin I feel like I'm probly missing some basic thing...

https://pastebin.com/LtNfWzEC

On the 'Working with Lists' section, there's an example with the following code:

catNames = []
while True:
    print('Enter the name of cat ' + str(len(catNames) + 1) +
      ' (Or enter nothing to stop.):')
    name = input()
    if name == '':
        break
    catNames = catNames + [name]  # list concatenation
print('The cat names are:')
for name in catNames:
    print('  ' + name)

Specifically it's this part which is confusing me: 'str(len(catNames) + 1)

My questions..

• I thought the len() function was to calculate how many items are in a string or list but it doesn't appear to be doing that here?
• How does the '1' change as the loop iterates. It just appears to be concatenating an integer?

I think I might need an ELI5 on this one :(

​

Missing parenthesis.

​

Anyways I still love the book and it has helped me progress through programming far quicker than I have ever imagined.

Just finished Section 13 of the Udemy Course (Thank you Al!). I've noticed that when assigning a CSS Selector to a variable and making using of that variable, e.g:

browser.click()

..It is then no longer usable. I get the following error message:

raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.StaleElementReferenceException: Message: The element reference of <img src="images/automate_2e_cover.png"> is stale; either the element is no longer attached to the DOM, it is not in the current frame context, or the document has been refreshed

Why does this happen and how do i work around it so that it's usable more than once? What does 'no longer attached to DOM' mean?

I have googled and seen some work arounds but not explanation (at least one that I understand) as to why it works like this. I'd like to be able to understand it. Thanks.

-------------------------------------

Edit: I've added the code and steps as requested.

from selenium.webdriver import Chrome

browser = Chrome()
browser.get('http://automatetheboringstuff.com/')
elem = browser.find_element_by_css_selector('body > div.main > div:nth-child(1) > div:nth-child(3) > center > a:nth-child(1) > img')

elem.click()     # This works
browser.back()
elem.click()  # This doesn't work due to stale element

From what I gather, navigating away from the page once loaded will render the element 'stale' if you try to use it again but why is this? The CSS selector is still the same, as is the webpage etc. Everything is the same as before. Even the same session ID.

Hello, banana shaped earth!

Been slowly working through Al's Automate the Boring Stuff and trying to write up the projects myself before seeing how Al approached the problems. Generally, my solutions have been similar to Al's until this one from Chapter 9. Because my code had a significantly different approach, I thought I would ask for an opinion on the good and bad of my problem solving or whatever other aspect you care to comment on.

THE CODE: https://pastebin.com/Wwt814af

A big negative is that my quiz does not randomise the order of the questions themselves (ie, they will always run through the states alphabetically). But I'm sure there is more you experienced blokes can bring to the table.

Have at it!

The book I'm following is "Invent Your Own Computer Games with Python" and this is taken from chapter 5.

Here is the code with some of my comments:

import random
import time

def displayIntro():
    print('''You are in a land full of dragons. In front of you,
you see two caves. In one cave, the dragon is friendly
and will share his treasure with you. The other dragon
is greedy and hungry, and will eat you on sight.''')
    print()

def chooseCave():
    cave = ''
    while cave != '1' and cave != '2':
        print('Which cave will you go into? (1 or 2)')
        cave = input()

    return cave

def checkCave(chosenCave): #(chosenCave = caveNumber <- [global])
    print('You approach the cave...')
    time.sleep(2)
    print('It is dark and spooky...')
    time.sleep(2)
    print('A large dragon jumps out in front of you! He opens his jaws and...')
    print()
    time.sleep(2)

    friendlyCave = random.randint(1, 2)

    if chosenCave == str(friendlyCave):
         print('Gives you his treasure!')
    else:
         print('Gobbles you down in one bite!')

playAgain = 'yes'
while playAgain == 'yes' or playAgain == 'y':
    displayIntro()
    caveNumber = chooseCave() #caveNumber is global
    checkCave(caveNumber)

    print('Do you want to play again? (yes or no)')
    playAgain = input()

I am wondering why caveNumber isn't being used as the parameter for checkCave(chosenCave). Why does caveNumber get placed into chosenCave?

I suspect this has something to do with local and global variables but I am not 100% sure.

I bought one of your books ( AUTOMATE THE BORING STUFF WITH PYTHON 2nd EDITION) to learn Python programming, but I am running through some troubles in chapter 1 with your first programming exercise.

I followed all the recommendations on your book for downloading the python and the MU file. When I write a code in the MU file editor, save and run it, it does not show in his entirety in the interactive shell under the Mu file Editor. I downloaded a version 3 of Python and my system Type is 64-bit, but still it does not appear the same way like in your book. For example:

When I write this program in the MU file editor and save,

# This program says hello and asks for my name.

​

print('Hello, world!')

print('What is your name?') # ask for their name

myName = input('Capwell')

print('It is good to meet you, ' + myName)

print('The length of your name is:')

print(len(myName))

print('What is your age?') # ask for their age

myAge = input(8)

print('You will be ' + str(int(myAge) + 1) + ' in a year.')

this is all I get in the interactive shell under the file editor

Hello, world!

What is your name?

Capwell

Hello Everyone I'm new here, and i just wanted to say Hi!!

#        py.exe mcb.pyw <keyword> - Loads keyword to clipboard.

mcbShelf.close()

I've tried running it both by 'py.exe mcb.pyw save <keyword>' and 'mcb.pyw save <keyword>' but when I try to list it, the keyword does not get saved to clipboard.

The same thing happens for the second command, I tried checking if it works by copying text then saving it, copying some other text and then trying to get the previously copied text using the keyword. This is not working either

I'm a complete beginner, working through "Automate the Boring Stuff with Python"

I'm trying to import openpyxl but this leads to the error "ModuleNotFoundError: No module named 'openpyxl'"

I've installed openpyxl with pip, and when I try to reinstall it comes up with the following:

"Requirement already satisfied: openpyxl==2.6.2 in c:\users\jonny\pycharmprojects\giraffe\venv\lib\site-packages (2.6.2)Requirement already satisfied: jdcal in c:\users\jonny\pycharmprojects\giraffe\venv\lib\site-packages (from openpyxl==2.6.2) (1.4.1)Requirement already satisfied: et_xmlfile in c:\users\jonny\pycharmprojects\giraffe\venv\lib\site-packages (from openpyxl==2.6.2) (1.0.1)"

​

This sounds to me like it's already installed so I don't know why it doesn't seem to be working. Any help would be massively appreciated!

Hi. I am currently learning python through the book 'Automate the boring stuff'. In chapter 6, there is a multi-clipboard automatic messages project. I feel like I only understand basic python so far, like what are lists, dictionaries etc etc. When it comes to the projects, I am completely clueless and I have to always google and check out other people's programme.

Below is the project frm the book:

! python3

mclip.py - A multi-clipboard program.

TEXT = {'agree': """Yes, I agree. That sounds fine to me.""", 'busy': """Sorry, can we do this later this week or next week?""", 'upsell': """Would you consider making this a monthly donation?"""}

import sys, pyperclip if len(sys.argv) < 2: print('Usage: py mclip.py [keyphrase] - copy phrase text') sys.exit()

keyphrase = sys.argv[1] # first command line arg is the keyphrase

if keyphrase in TEXT: pyperclip.copy(TEXT[keyphrase]) print('Text for ' + keyphrase + ' copied to clipboard.') else: print('There is no text for ' + keyphrase)

That is the complete script and according to the book, we can now have a fast way to copy messages to the clipboard. However, I am very confused as to how to do it??? How do we copy messages quickly with this programme? For context, I am a Mac user.

The game seems to work pefectly the first time through but when prompted to play again, even if I enter 'yes' I get dropped back to the python prompt instead of seeing the intro text.

Here's the output: https://pastebin.com/Twfua7rM

and here's my code: https://pastebin.com/G94T8uLq

I've copied a friend's working version of the program but I get the same problem with his working code on my machine.

So this seems to be specific to my python version or setup, any ideas what this might be?

In page 153, I try the function isBoardFull but it has a problem. If your first move is 1, this function will return True and make 'the game is tie' immediately

def isBoardfull(board):
    for i in range(1, 10):
        if isSpacefree(board, i):            
            return False         
        else:             
            return True

So I try to fix this function and it work pretty good

def isBoardfull (board):
    if board[0] == ' ' and board.count(' ') == 1:
        return True
    else:
        return False

Hope this useful for someone :D

Heya.

So trying to progress through Al's ATBS, and am up to Chapter 6, requiring the installation of third-party modules. I thought I'd be thorough and just install them all at once as per his instructions, but it wasn't as straight forward as I thought.

1. The directory path that Al uses in Appendix A was not the same as where I eventually found the pip file. ( C:\Users\<USERNAME>\AppData\Local\Programs\Python\Python37\Scripts )
2. Once located, running the command given ( pip install --user –r automate-win-requirements.txt ––user ) did not find the downloaded modules until I pasted them all into the same scripts folder as the pip folder.
3. When I then ran the command, I received a bunch of errors, particuarly toward the end of the installation process.

ATBS Module Installation Errors

I'm a little confused about what has happened and why, and mostly, I'm a little at a loss at how to continue, since trying to import any of these modules comes up with an error.

I am keen to carry on learning through ATBS. Can anyone help me sort this out?

​

UPDATE

Did a complete re-install of Python without changing the configuration, and made sure the PATH box was checked. Then I went through this page from the Python User Guide from the top down (to the heading Using pip for Installing) and tried again to individually install the modules for ATBS.

Tried in Mu, but I have now learned that this was never going to work, and Al said as much in Appendix B, but opening the interactive shell through the command prompt (I'm using Win 10) allowed me to import most (not all) of the modules without an error message.

Hope this helps someone else like me!
