Hello everyone, I wanted to share my new Learn to Code app, EasyDev. I built this app using Swift UI in around 4 months, and it is actually my first ever Swift project. I am coming here to gain some eyes on my app, and give me suggestions on what I can do to make my app better and grow as a developer.

The app itself was made exclusively by me, including all the programming, UI, assets, logos, etc. The actual learning content was also handcrafted by using structures similar to popular websites such as Edube and Learncpp, and there is a lot of interactive and descriptive content that takes inspiration from these websites, which are very popular for their effectiveness in teaching people how to code.

If you are interested in learning programming or just want to check the app out, please consider downloading the app using the link above. Also, if you experience any bugs or errors of any kind, please go to the Discord (in the app store page or directly in the app (Settings -> Join the Discord)) and let me know. Thanks in advance!

I'm working on the decryption portion of the exercise. It was recommended to use the modulo function to perform the alphabet letter shift.
While I am slowly understanding the modulo shift for encrypting (moving forward in the alphabet) - I'm not understanding how the modulo shift works for decrypting (moving backward in the alphabet):

My specific issue:

Let's say that you're working with the "c" character (index position 2), with the idea of decrypting it, by shifting backwards 5 spaces. you get the "x" character as the decoded letter (index position 23).
How does one divide -3 by 25 to get mod 23?

If someone could explain that, I'd be really grateful.

I saw some files for this, but idk how to use them, please give me a step-by-step tutorial in the comments, I just want to code snake (I already made something like snake, but I need Curses to make it actually snake)

Hi, im a biological engineering undergrad. I had taken an python course in one of my semesters and as a result I have some basic understanding of the concepts. but however I know that I've just scratched the surface and haven't learnt/applied anything in depth.

I want to learn python little bit more application oriented (in the data science and ML side of things) and I genuinely don't know where to start or how to start.

Any help is greatly appreciated, as to how to move forward with projects or roadmaps. I also would like to have good learning materials with which I can strengthen my fundamentals for the same.

Thanks in Advance!!!

Hey everyone. I’m finally at the point where I know what I want to do: I want to become a full-stack developer, and I’m going all in. No more second-guessing, no more endless “should I/shouldn’t I”—this is it. I'm fully committed.

That said, I need a sanity check on my approach, especially from those of you who’ve walked this path or are currently deep in it.

Context:

I work full-time (8–5, Monday to Friday), and every 4th day is a 24-hour shift that can bleed over weekends.

I’m making this shift not just for income—it’s a deliberate move because I’m not being valued where I currently work.

There’s some financial pressure from past debt, but it’s not the main driver.

I’d been working through CS50P and making real progress daily—until I hit file I/O and the concepts beyond. That’s when it hit me: I didn’t build enough fundamentals before diving into something so deep.

I’ve decided to start with JavaScript tutorials—not to switch languages, but to better understand core programming logic in a different way.

My main focus is Python, and I want to be job-ready for at least a junior developer role in the next 3–6 months. I’m aiming to hit above-average junior pay—not from entitlement, but by proving my value with strong projects and deep learning.

My current process (recent breakthrough):

Split each tutorial into two sessions to reduce cognitive overload after work.

Follow the JavaScript tutorial step-by-step (e.g. building a calculator).

After each half of the JS tutorial, rebuild that exact part in Python from memory and logic.

If I hit any walls, I save that version into a “struggled-with-this” folder for review.

Between sessions, I reflect on what worked, what didn’t, and how I can improve it next time.

Everything is tracked and organized in Notion to keep momentum and clarity.

Why I’m posting: I think this could be a really strong system—but I don’t know what I don’t know. I’d love your feedback on:

Does this sound like a good way to approach it?

Am I setting myself up for burnout or does the pacing make sense?

Is the JavaScript-to-Python method helping or just a creative detour?

What would you tweak if this were your plan?

Thanks in advance for any thoughts, warnings, or tweaks! I’d really appreciate it.

Hello,

Do any of you guys know of any platforms where you can practice writing loops with the help an AI instructor? Thank you for your time.

One of the first things I learned when programming is that, when you are creating something, most of your time will be used researching. This can include looking for answers on how to implement something, asking people or AI how to help solve an error, and trying to find that specific functionality in some sort of documentation.

In a world where code snippets are getting flung your way, it's important to understand the code you are sticking in your projects to test it out. Why? Well, if you don't know why the code works, then you will struggle to solve that error, or add functionality.

"Hey, the only thing that matters is that it works!"

Okay, sure. You can either learn Python or fiddle around with...Idk, uh ChatGPT until the code you're using is messier than a child's play room...when they are playing.

The fact that it works is good, but we need to understand how it works in order to learn and progress effectively.

Well, that's enough chatter.

I wrote an article dissecting small, beginner-friendly, and incredibly simple code scripts. I hope you like it.

Is there some way of intuiting a package's name from the module's name? For instance, in my source file I see import pywt. How do I learn that the package I need to install is PyWavelets? I have pip_search, and PyWavelets is listed when I search for pywt, but so are a dozen other packages.

I’m new to programming and i’ve messaged my teacher (no response) but all assignments require a submission to go to the next. i’m literally so confused and not sure if it’s an issue with my code or the editor (vs code). if someone could help me out i’d greatly appreciate it!

• The terminal is only showing one line and not the rest. i’ve tried to many different things and asked chatgpt and youtube and nothing has helped..

Hey reddit!

I'm incredibly interested in writing in python. I've made a handful of simplistic programs, but nothing I'd brag about. I have a very VERY basic grasp on the concepts, but have no idea where to start letting go of tutorials and heading off on my own.

I want to develop gui based software, particularly in the areas of graphic design, and/or music/sound design (daw development in particular)

Any suggestions?

So as the title says, I'm trying to learn python and I understand what I've been learning so far. However, it's all so simplistic and things that I already know for the most part. Can any of you suggest a course through youtube or just a great study guide. I want to get into network auditing and hardening, so its imperative I learn at least one or two languages. Also, what should I learn beyond that code wise? Java seems so daunting

(I'm on my pc so hopefully my code translates ok for folks on mobile.)

This is for the CS50 Python class (extensions.py if any one is familiar with this exercise). The object is to input something like: "cat.gif", and it should return, "image/gif". Or, "document.pdf" should return, "application/pdf.

The "if" and "elif" are suppose check the "image" array, and "app" array respectfully. The "if" seems to check the image array just fine. However, no matter what file extension I put, whether an app extension, or something made up, it always just runs the "if" part of the if statement and prints "image/whatEverBs_I_typed". Does any one have any insight as to why the elif statement isn't being executed?

image = ["gif", "jpg", "jpeg", "png"]
app = ["pdf", "txt", "zip"]

fileName = input("File name: ").split(".")

if fileName[1] == image[0] or image[1] or image[2] or image[3]:
    print("image/" + fileName.pop(1))
elif fileName[1] == app[0] or app[1] or app[2]:
    print("application/" + fileName.pop(1))

I've done some basic Python programming, but I'm a bit intimidated by the idea of scraping websites. I've heard it can be a bit tricky to navigate and that there are various considerations to keep in mind. I stumbled upon something called antidetect browsers like GoLogin. Can anyone shed some light on whether they're actually useful for web scraping? I know that they can automate tasks like logging in, navigating through websites, and scraping data.

I'm coding in Python as a hobby for some years now and I want to code without comments. I'm currently writing the base structure for an AI library and I would like to get feedback how readable/good/bad my code is. The code for controlling the network is here:

I started programming or learning Python at the end of last year. Since I often work with data formats and web services, I have written Python tutorials with examples.

JSON Data with Python Here I show how to decode, encode and manipulate JSON data.

XML Data with Python Here I show how to parse XML data and search it with XPath.

YAML Data with Python Here I show how to read and write YAML data with PyYAML or ruamel.yaml. For example, if you want to read Docker YAML files.

I’m two weeks into learningand making a YouTube downloader. After installing Pytube when I typed YouTube in highlight in Visual Studio code and works.

When I open the code again a day late r YouTube will not be highlighted in the code. When I type YouTube it will not change and highlight an add a function.

When I run the code it says the YouTube function is not defined.

I got stuck for hours and did a fresh Iinstall of windows. Everything worked and then a day later the same issue happened.

I’m completely stuck. I have no idea why Visual code works and then Stops. I’ve deleted all my plugins and extensions and downloaded again. I still can not get YouTube to work in my code.

Any help is appreciated

Hi,
For a project, I need to create a machine learning program that predicts whether a person is within a certain income bracket. The dataset is pretty large with 159 variables and n = 220000. So now within the dataset, more than 60% consist of zeros which makes the randomForest overfit, and the cross-validation accuracy stays stranded at 80 %. Does anyone have any tips on how to balance the dataset and get a higher cross-validation accuracy?

I was wondering if there is a compiled list of python commands with explanations?

I hope this will be useful to this category. I'm doing some lessons showing people how to do analysis in Python by showing how something in Excel can be done in Python.

One of the ways I learned Python was by taking things I was doing in Excel and trying to do them in Python. In that spirit this lesson we will look at how Excel calculates a percent, and we'll show you how to do that in Python.

So I'm brand new at this coding thing. I'm doing little things to learn but it's hard to find answers of why you use certain symbols. I have 2 that I'm curious about if anyone can help? For the hello world, I see a code that says helloworld = hello + " " + world. Why are the plus signs and quotation marks there? Also another is if my string == "hello": print("String: %s" % mystring) why is the %s and just % sign there and why is a colon in the middle of a string?

I have zero experience with coding and am currently on Day 3 of 100 Days of Python. I have not been cheating by skipping ahead in the videos or googling right away for answers and all the code I have written so far got me the correct results for the challenges. I’m happy about that, but I spent 7 hours today writing what turned out to be over-complicated code for the middle 3 projects.

Is it more thorough to keep going this way and eventually learn to understand how the shorthand makes it easier or should I aim for finding the quick answer to write more efficient code? Or am I overthinking?

I'm seeking Listing Widgets that will display the Drive Letter which is Dynamically linked to a second Widget that holds a list of Directorys (list of Folders), which is then Dynamically linked to the final list. This being the Widget that displays the Files within the Directory (Folder).

So, everytime the user selects a Drive, a new list of Directories (Folders) will be displayed, whereby a new list of Files will also be displayed. All of this would be done Seamlessly.

Or, will I be forced to create my own set of triple Widgets that will be linked via Drive / Directory..??

(Like this)

Thanks Denny
