I built a python debugger specifically for learning data structures and algorithms.

It draws the state of the program at each line. It's an actual debugger that runs with the code, so the results are deterministic and show the real state.

Like a normal debugger, it lets you inspect stack frames, pointers, and objects. But instead of showing them as raw values, it draws every data structure in its own way. It knows how to draw all the common data structures like trees, graphs, queues, stacks, linked lists, etc.

This should be helpful for understanding, debugging, and verifying your code.

You can try it on popular interview problems (write your code or paste from the "Solutions" tab).

Everything is free. Feedback would be really appreciated. Let me know what you think.

Hi everyone!

I'm learning Python and exploring how I can turn my skills into a small freelancing business. I'm particularly interested in Python automation, Google Sheets automation, and simple workflow automation for small businesses.

I don't want to jump into freelancing without understanding what clients actually need. My plan is to learn by building practical projects, create a portfolio, and gradually start looking for clients.

Some services I'm considering learning to provide are:

- Google Sheets automation: Automating repetitive spreadsheet tasks, reports, data cleaning, and calculations.

- Python scripts: Automating repetitive file operations, CSV/Excel processing, and routine data tasks.

- Workflow automation: Connecting tools and reducing manual work where APIs or approved integrations are available.

- Data processing: Cleaning, organizing, and transforming business data into useful reports.

I'm still developing my skills, so I want to focus on solving real problems rather than claiming expertise I don't have.

I'd really appreciate advice from people who have experience with Python or automation freelancing.

A few questions:

1. Is Python + Google Sheets automation a realistic niche for a beginner freelancer?

2. What specific problems do small businesses actually pay freelancers to solve in this area?

3. Which skills should I learn first: Python, Google Apps Script, Google Sheets formulas, APIs, or SQL?

4. What 3–5 portfolio projects would help demonstrate practical skills to potential clients?

5. How difficult is it to get the first paying client, and which platforms or methods are worth trying?

6. What mistakes should a beginner avoid when starting out?

I'm not expecting instant money. I want to build useful skills, deliver reliable work, and grow gradually.

If you've tried this path yourself, I'd love to hear what worked, what didn't, and what you would do differently if you were starting again.

Thanks for reading!

Hi everyone, I’m an Australian solo founder building Forge, a personal AI platform focused on persistent knowledge, evidence-based reasoning and keeping the owner in control.

The question behind it is: how can an assistant become more useful over time while keeping its knowledge traceable, its mistakes correctable and consequential changes subject to human approval?

I’m developing it in Python with a modular, service-based architecture. There’s working code covering knowledge storage, retrieval, evidence handling and reasoning, but it’s still under development. My immediate focus is reliability, testing and bringing the pieces into dependable everyday use.

My background is in commercial fishing. I started learning software development through this project, initially working on an Android phone with Termux. I use AI coding assistants extensively, and I’m putting serious effort into understanding and verifying the results.

I’d like to connect with someone experienced in software architecture, AI systems or taking an ambitious prototype towards a maintainable product. An occasional conversation would be valuable—someone who can challenge my assumptions, spot unnecessary complexity and help me judge what deserves attention next.

I’m looking for perspective and honest criticism, rather than someone to build it for me. I can bring focused questions, diagrams and small, sanitised examples without sharing the full private codebase.

If that sounds interesting, I’d be very appreciative of a comment or message. Recommendations for communities where this kind of mentoring happens would also be welcome.

Thanks for reading!

I'm 27M. Hey everyone, my life has been a little different from that of most people, and I don't have a strong educational background.

Right now, I'm working at a grocery store, but I want to improve my life and learn some stable, valuable skills that can help me earn a reliable income.

I've come across these four skills:

Python

SQL

Excel/Spreadsheets

Power BI/Tableau

I don't know much about these skills or their demand, competition, value, and future prospects.

Technology is constantly evolving, trends are changing, and AI is replacing some jobs. The value of different skills also changes over time.

Before I start learning, I want to understand whether these are the right skills to invest my time in for a stable career and income in the long run.

I'd appreciate your advice. Should I go for these skills, or would you recommend something else?

Fy DS student and I recently had a Python test that honestly didn't go as well as I expected.

The frustrating part is that I wasn't completely clueless about the questions. I understood the concepts, knew which syntax was needed, and could understand what the problem statement was asking me to do.

But when it came to actually applying everything and writing the code, I got confused. I started forgetting things, made indentation mistakes, got errors like ValueError and other errors etc. I didn't do good in test it was 15marks test for 1 hr.

For those who have been through this, how did you get better at applying concepts under pressure instead of just understanding them theoretically? Did you practise more problems, rewrite code from scratch, or follow some other method?

I'm still learning, and I don't want one bad test to discourage me. I just want to figure out how to improve so that next time.

I am looking to purchease Complete Python Developer in 2026: Zero to Mastery course from ZTM... Its very expensive. Is this course updated recently?

As developers, we are constantly learning new things, but sometimes one tool or concept completely changes how we approach our work.

What's something you learned that made you more productive or helped you solve problems in a better way?

It could be a programming language, a tool, or even a simple workflow tip. I’d love to hear your recommendations.

Ran into an annoying performance bottleneck while profiling our CLI and figured the findings might save someone else a few hours of head-scratching.

Our tool validates config manifests against JSON Schema Draft 7. In fresh virtualenvs, cold-start imports were taking over 5 seconds.

Profiling revealed two primary culprits:

1. **jsonschema.Draft7Validator eager compilation:** Instantiating the validator compiles heavy format checkers and regex dependencies (Lark and RFC 3987). If you instantiate this at module level, every single CLI invocation pays that cost even if the user just ran --help or a command that doesn't touch schemas.
   • Fix: Defer instantiation via module-level __getattr__ or initialize it only when validation actually executes.
2. **importlib.metadata.distributions() traversal:** Scanning installed distributions without boundaries linearly inspects every .dist-info directory on sys.path.
   • Fix: Replaced it with scoped directory globbing for our specific package metadata prefix.

Startup dropped from ~5.2s down to ~150ms.

We rolled this out in Skillware 0.6.0 (an open-source project we maintain for deterministic agent tooling: https://github.com/ARPAHLS/skillware).

Are you folks deferring schema compilation in your CLIs, or do you prefer pre-compiling/caching schemas during package build?

okay i've been searching this online for abt like 30 mins now and i've gotten no results or remedies to my problem

in ctk/tk i made a mainloop or whatnot, standard stuff but as soon as i make a ctk.ctktoplevel and do protocol("WM_DELETE_WINDOW",func=whatnot) WITHIN the ctktoplevel, if i close the main GUI that isnt the ctktoplevel, it will trigger the function. why?

This beginner-friendly Python project demonstrates how to build a command-line calculator using input(), float(), conditional statements, and arithmetic operators.

The calculator supports:

• Addition, subtraction, multiplication, and division
• User-selected operations
• Decimal number inputs
• Invalid-choice handling
• Division-by-zero checks

Try implementing the calculator yourself, then extend it with a loop, exponentiation, or modulo operations.

What feature would you add next?

Code. Build. Innovate.

Hi Reddit, I just finished a short novel (2028) about working alongside AI models and wanted a completely offline, zero-dependency publishing workflow. I wrote a small script (tools/build_en.py) that uses only the Python standard library to process Markdown sources into clean HTML and valid EPUB artifacts for e-readers like Kindle. Repo: [https://github.com/peterkokosharov/2028-book](https://github.com/peterkokosharov/2028-book) Feedback on the build script or the text itself is very welcome in GitHub Discussions!

I am a second year CS student and cybersecurity is my specialty call. Python sits on my list as the tool language for that road. Not mastered. Just next. For people who learned Python for security work what did you start with? Automating small tasks or web basics or something else entirely?

I'm learning Python while also trying to build a SaaS product, but i have no previous development experience. Right now, I rely on ChatGPT or Claude for almost 99% of the coding.

Is this a reasonable way to learn as a beginner, or will relying so much on AI slow down my progress in the long run? Will i eventually become capable of coding independently?

I have a college assignment to make a multiplayer tetris game (2 players) using TCP sockets, client and server and all that. The idea is the server doing most of the stuff, chosing new pieces, handling the translation of position of the pieces, with the clients being responsible for most the rendering/display part and getting the inputs(I think so at least, that's what I'm trying to do), but I'm having a hard time with it.

I can't seem to think of a way to have the client call to the server to send a new piece to the clients, and if I don't know how to do even that then I don't know how to do anything else (making the back and forth for controlling the pieces, both for the player of the client and the preview of the game of the player 2, and all the rest), tho I hope if I can understand how to do one thing I would be able to make the others, but I really don't even know how to do this.

I know I need to use threads on this, tho I don't really know how to do it, I'm still fairly green on python too so, if anyone could give some help in any way with this it would be much appreciated.

Hi All,

I am learning Python and would like to know are there any good sites to practise Python concepts ?
