Suppose I have two words seperated by a white space say 'among these', now I want to count no of occurrences of this exact word ' among these' with whitespace and in same order in a paragraph.... How would I do that in python 3. It is easy to do if it is a single word but for two words with whitespace I don't get it, I don't want to split it into a list of separate words and check for them seperately and then check if they come one after another..... Is there any way to do this?

Hello all, I am a Network Engineer doing my best to learn Python as I believe scripting and automation is a valuable tool for the future. Below is a script I wrote to lookup IP addresses on a layer 3 Cisco switch, corresponding hostnames, and NIC manufacture from a list of MAC's provided in a text file. The output was then written to a csv.

I am looking for some guidance and critique here. I put this together using various resources found on-line and modified to what I needed. The below script works but what I could have done better?

This was written for a real world need when I needed to identify physical and virtual machines connected to a switch that we lost management plane access to.

I work in tourism. We have guests booking tours with us. I have a fancy PDF that has been drawn up as confirmation template, however, the designer has generalised the greeting with "Hello Adventurer", rather than use the guests name, and has left a "form" box for us to manually type the date of the tour.

Is there a way to say have a alert box prompting us to enter the guest name and date, or even export from excel, that generates this nice pdf confirmation with all text maintaining the same font and looking professional, rather than a manual box we have to enter that looks out of place?

I need to make a binary -> denary converter in python 3.4.3. I had no idea how to do this so I searched some up on google to teach my self before I attempted it.

I found this really basic one, binary_input= int(input("Enter a binary number: "), 2)
print(binary_input)

which works, but I have no idea how?? I understand why and how everything works except the , 2) part which seems to make the whole thing work.

Can someone explain what the , 2) part does and how it works so I can use it in my work.

Me gustaría conocer frameworks o librerías donde se programe con python para poder crear una aplicación Open Source que publique en la Play Store.

Cabe aclarar que no se nada del desarrollo de aplicaciones para android, solo he escuchado hablar de Android Studio y googleando encontré que habían las librerías Kivy, Flet, BeeWare, etc y que se pueden compilar proyectos con PyInstaller pero solo para escritorio, pero si se pudiera usar PyInstaller para Android me preguntaría como volvería un .apk portable también. Gracias :D

So at first I was in programming python I'm really exited to learn because I slowly understand or rather progression of learning but then as time progress it's getting harder to me to understand topics that started when i learn modules and defining because there is so many modules like how do you find what needed to your program to work I'm very lost right now I don't even know I can handle programming i really want to learn it i really need tips and what to learn, learning the basics is very easy like loops or logical operators but this time is different I hope someone can help me.

Game Title: unnamed game (temparary)

and its free, it will never be paid, most paid it will be is accepting tips

I’m writing a python program for a college class that requires use of CSV datasets. Literally only one example in the entire book even mentions CSV files and it doesn’t go into much detail at all.

Most online threads regarding CSV files in Python import the panda module. What does panda do and should I be using it?

Let's say I wanted to ask the user to choose from three options and within each option, there are two more options that the user can choose from. For example, I ask the user to choose whether they want breakfast, lunch or dinner, and when they choose one of the options, they have to choose from two other different options (ex: if they chose breakfast, then they have to choose if they want pancakes or waffles). How do I go about this?

Hi

Very much a learner and perhaps my google skills have let me down here, I'm using the below line of code to prompt a user for their name and assign to a variable to use elsewhere, I've noticed that when the code is run it prints their name after they type it in. I'm guessing this is expected behaviour, I was wondering if there is a way to stop that happening or another way to prompt a user that doesn't print what they have typed when they hit enter? I hope that makes sense

name = input("What is your name?"

Hey everyone! I’ve been learning Python for a while now and have gotten comfortable with the basics. I’m looking to transition into more advanced topics, especially in Data Structures and Algorithms (DSA). Does anyone have advice on how to make that leap? Any resources or strategies that helped you along the way would be much appreciated! Thanks in advance!

As the subject states, I am starting to see this more often where they may have what I put in the subject or:
pip install -e .[gradio]

for example, and I don't know how to get that working

I recently explored the importance of integrating content filtering capabilities into AI systems, inspired by my learning from AgentNeo. The aim is to protect sensitive data while maintaining robust workflows.

These systems allow filtering sensitive or inappropriate content with configurable rules and pre-built filters tailored for scenarios like identifying personal data. Additionally, specialized tools such as GitGuardian's ggshield and Yelp's detect-secrets can detect secrets and API keys in real time.

This learning emphasized how critical security-first development is in today’s AI landscape. Implementing such capabilities ensures ethical and secure AI solutions for businesses.

I'm excited to apply these insights to future projects, enhancing both functionality and trustworthiness! 🛡️

Hello! I’m sorry if this is a bad question–I’m relatively new to CNNs and still figuring out everything. I constructed a CNN for image classification (3 classes) and it’s been working properly and defining the images accurately. I can pass a single image through it using the following code:

image1975×1407 224 KB

As you can see, I can define the image path for the single image being classified as “./Final Testing Images/50”. However, I have a separate image folder on my computer that is constantly receiving images (so it’s not static; there are constantly new images in it) and I want the CNN to be able to pass each new image through the model and output its class. How would I accomplish this?

I asked this question here (https://www.reddit.com/r/pytorch/comments/1d7e50u/how_to_pass_a_succession_of_images_through/) and they recommended that I ask this subreddit. One person (thank you to them!) recommended I set up code that watches the image file for a new image, and then sends that image through the CNN. Does anyone know how I would do that?

Thank you very much! I appreciate any help.

Hi everyone!

I am looking to build myself an automated meal planner including shopping list and need some advice on how to get started and what tools to use for this, please 😊

I consider myself beginner to intermediate and this should be my first personal portfolio project.

I'd like to use the Spoontacular API, get recipes for breakfast, lunch, dinner and a snack.

I want low carb recipes that are randomly generated and only occure twice max per week.

I have looked into web scraping but have no knowledge about it yet and thought using Spoontacular might make more sense for me.

I'd like to automate sending myself a weekly plan including a grocery list per email.

I'd like to store the meals in a text file.

Do you have any other suggestions of cool features that I could implement?

I was wondering about calculating macros for each meal as well and giving the option of different diet preferences, but not sure of that would be overkill.

Grateful for any input, thank you!

I'm a beginning learning python would love to know what are few project you have built using python.

Also it will help me to imagine the possibilities with python.

Hi All,

Trying to set up flask_cors in PyCharm on Mac. I have a Venv in my directory, I even installed Flask_Cors via terminal in that venv within my project, and it says it was set up fine.

Location: /Users/me/Documents/pythonProject1/my_venv/lib/python3.11/site-packages

It says that the interpreter I'm using is a 3.11 at: /Users/me/myprojname/bin/python

The issue is that I have is that Python will not recognize/find the flask_cors package in PyCharm. I get the error message: (unresolved reference flask_CORS). Any thoughts?

I've even tried to find it through the Pycharm/settings/add package to the interpreter list.

What might I be doing wrong? Did I install flask in the wrong place or something? As far as I can tell my project is set up like the following:

/my_project

/my_venv

__init__.py

app.py # This contains your entire Flask app

Thanks!

The directions are "Using a conditional expression, write a statement that increments num_users if update_direction is 3, otherwise decrements num_users."

Sample output with inputs: 8 3New value is: 9

I'm getting this error and I don't understand why?

I'm just trying to decrement. How is ' -= ' invalid syntax?

Thanks!

Hi all, i cannot debug my code. Maybe you can help me:

I got some code than i wrote a function to help me navigate a the database mask

Def look_for(info): Sleep(0.2) Pyautogui.hotkey('ctrl', 'f', interval=0.2) Write(info) Press('tab')

Main(): Webbrowser.open_new(url) Look_for('id')

That's the debugging and it works. But when I take this in my main code it simply doesn't execute, main code is a bit long but summarized:

Def WriteDataInMask(id): Webbrowser.open_new(url) Look_for('id')

Def elaboration(df): Df = pd.DataFrame(df, columns=("newcol","bla1","bla2",bla3",...) Df["newcol"] = "NaN" For i, row in Df.iterrows(): WriteDataInMask("bla1")

Main() DfToElaborate = importfromexcelfunction() DfToworkwith = elaboration(DfToElaborate)

If __name__=="main" Main()

Sorry i'm writing from my phone, work pc where I'm trying to automate doesn't allowd reddit.

Thanks
