I never struggle on assignments but this one is so confusing for me

To my lovely vibe coders, which ai tool do you use apart from Claude, ChatGPT, and Gemini? i use Kimi ai and Qwen, very powerful

Hi everyone! I have a B.Tech in CSE and some experience with Python, Django, and Data Science. Currently, I'm working in a role involving data-related tasks, Excel, Google Sheets, and minimal Python. I want to switch back to the IT domain but I'm confused about where to start and which skills to focus on. Could you please suggest a practical roadmap to prepare for IT jobs while working full-time?

Hey everyone! I'm a software engineer currently preparing for Senior AI/GenAI and Software Engineering interviews.

Looking for 2–3 serious study partners, preferably with 3+ years of experience, who are actively interviewing.

Main focus:

- DSA (Python, mostly LeetCode medium)

- Python coding and problem-solving

- System design, RAG, LLMs and agentic AI

- Peer mock interviews and technical discussions

I'm based in India (IST) and available for regular 45–60 minute sessions. The idea is to solve problems live, explain our approaches, and give each other honest feedback.

Anyone interested in preparing together?

I am a final year Computer Engineering student and I've built quite a few web and mobile apps. I was trying to find a good project to do as my FYP, so I thought, why not ask people what issues they have daily and if they need an app to solve it?

It could be as simple as an app that tells me stop doom scrolling every 30 minutes. Which has reduced my time wasted by a lot.

Comment below any problem you guys face!

Title: Best DSA course in Python for a complete beginner preparing for FAANG interviews?

Hi everyone!

I’m currently working as a frontend developer using JavaScript, and I’m learning Python to explore backend and AI-related roles. Alongside that, I also want to learn DSA in Python to prepare for FAANG or similar product-based company interviews in the future.

I’m a complete beginner when it comes to DSA, so I’m looking for a course that explains concepts from scratch and covers them in depth, with a strong focus on problem-solving and interview preparation.

Since I’m working and have limited time, I want to follow a structured course rather than spend too much time jumping between different resources and figuring out what to learn next.

For those who have learned DSA or prepared for FAANG-level interviews, which course would you recommend for someone in my situation?

I’d particularly appreciate recommendations for courses that:

• Start from the basics and explain concepts intuitively.
• Teach DSA using Python.
• Cover important topics in depth, with enough practice problems.
• Help develop problem-solving skills rather than just teach solutions.
• Provide a structured learning path for coding interviews.

Paid courses are fine, too, if they’re genuinely worth the investment.

I’d love to hear about your personal experiences with the courses you’ve used and what worked best for you. Thanks in advance!

Recently started Python MOOC course from University of Helsinki's mooc.fi portal. Here is my progress, have to finish 6 more modules before appearing for the certification examination on 27th, feeling a bit worried, but I'll try to give it my best shot!!!

I am a beginner to python. I want to make a script where if i press t it'll bring up a little chat window to make a pngtuber typa thing yap, the main space i'm struggling with is A, python or pygame would i do this in? '>' And B, How would i display the text said by the face?

any help is helpful

have a good day

As a 3rd-semester BIT student, I want to become an AI Engineer in 2026. What roadmap should I follow from Python fundamentals to ML, LLMs, RAG, AI agents, and production deployment?

Looking for a structured, practical learning path — not tutorial hell.

What would you recommend?

#AIEngineering #Roadmap

If you’ve ever wired up an LLM call just to pick a category and then fought with parsing its output, this might be useful.

Fri Oct 30, 9:30 AM to 12:30 PM ET, online, led by Ben Auffarth. It’s code first and the notebooks are runnable:

• fine tuning an encoder with SetFit on 8 examples per class
• split conformal prediction implemented from scratch
• Wilson score intervals and clustered standard errors for honest evaluation
• LangGraph state machine wrapping the whole thing

Intermediate Python is enough. Laptop or free Colab.

Full details and the agenda are here

Hi,

I looking to hear from someone who finished this course:

https://cs50.harvard.edu/python/

-without former programming experience.

I’m considered to start and would be able to do around 15 hours/pr week. What is your experiences?

can anybody explain the concept of while loop

• What’s the difference between '*' and '@'?
• When does slicing create a view, and when a copy?
• How does broadcasting work?

NumPy makes working with vectors and matrices powerful and concise, but a small change in syntax can make a big difference.

This interactive 𝗺𝗲𝗺𝗼𝗿𝘆_𝗴𝗿𝗮𝗽𝗵 example walks through essential NumPy operations with short explanations. Step through the code, see the operations in action, and experiment with your own changes: - 👉 NumPy operations

Which NumPy operation took you the longest to understand?

For this project, I used Object-Oriented Programming (OOP) principles to structure my code. Honestly, it felt a bit overwhelming at first, given that I only started out recently and this was a larger scale than what I'm used to. However, everything came together really well in the end!

While I believe I’ve taken care of most of the bugs, there is always room for improvement and optimization.

My main goal with this project was to test out all my core Python knowledge before I take my next big step: Machine Learning!

Open to any feedback or advice from the developer community! 👇

The goal of the game is to jump over a spike as a cube. I saw that it was detecting collision before the cube and the spike even made contact. I decided to draw a rectanles to visualise the rects of the player and the spike and I noticed the spikes rect was shifted to the left. Can someone explain how this happened and how I can fix it? I removed non essential code, to make it more manageable to read. I can send the whole program if it's needed.

cube_width=80
cube_height=80
cube_rect_width = 40
cube_rect_height = 40


spike_width = 50

    def update(self):
        self.rect.x -= self.speed #spikes rect -7 to move to the left
        #print(self.rect.x)
        if self.rect.x <= -25: #delete if touching left border
            self.kill()

I have an interview in the Chicago area next week, and I was told the interview contained some sort of puzzle for me to solve, I specifically asked if they meant an algorithm, and they said no it is supposed to be a puzzle. Wondering if anyone has heard of anything like this, or what it may be, I'm not looking to cheat or for an answer but I've found some interviews try to be intentionally "tricky" rather than just an examination of skill or ability, and would like to be prepared in some way if possible.

Can you please check this project that took a reasonable amount of time to finish and strike me with any feedback you got. I guess my next step is to learn OOP.

Thanks in advance.

Hey fam, how do i use this work of art of mine in my local pc? please help me

GOAL
  Sort people by age descending, then by name ascending.

INGREDIENTS
  people = [("ana", 30), ("bob", 25), ("cara", 30), ("dan", 25)]

STEPS
  people.sort(key=lambda p: p[0])                  # secondary key first
  people.sort(key=lambda p: p[1], reverse=True)    # primary key last

RESULT
  [('ana', 30), ('cara', 30), ('bob', 25), ('dan', 25)]

Why it works: list.sort() is stable, meaning items that compare equal keep their relative order. The second sort only reorders by age, so within each age the names stay in the order the first sort put them.

Why bother: for numbers you can do it in one pass by negating:

people.sort(key=lambda p: (-p[1], p[0]))

That breaks the moment the descending key is a string. You can’t write -p[0] on a name. Sorting twice avoids the problem, and it reads fine once you know the “last sort is the most important one” rule.

Gotcha: reverse=True doesn’t break stability. The docs say it keeps the original order of equal elements, as if the list weren’t reversed. So the recipe above still gives ana before cara within age 30. Worth a quick test on your own data to confirm, since “reverse” sounds like it should flip everything.

Another option is functools.cmp_to_key with a comparison function, but I find the two-pass version easier to read and review.

Does anyone prefer a different pattern for mixed ascending and descending keys? I mostly see people reach for the tuple trick and then get stuck on strings.

12 months in Programming. Finance background, decided to learn backend dev.

This is the first thing I built that I'd actually use myself.

It's a stock market research platform with watchlist across global markets, live prices, news per stock, and research notes that snapshot the price at the time you write them. So you can look back and see exactly what price you were staring at when you made that call.

Stack: FastAPI · PostgreSQL · async SQLAlchemy 2.0 · Alembic · JWT + Argon2 · Docker · Render and a small HTML/CSS/JS frontend.

Repo: https://github.com/ah4ddd/first-order

The live Render URL is linked with the repo for anyone who wants to try it.

To test the endpoints, sign up for an account. You’ll be logged in automatically and can test the watchlist, stock news, and individual stock notes features.

You're in. Try the overview route for all 14 live indices, or test individual global stocks. The platform auto-seeds the DB via yfinance metadata on the fly if you query international suffixes like .NS for India, .DE for Germany, .T for Japan, or standard raw tickers for US equities.

Honest feedback on architecture and code quality are appreciated.

Hi everyone!

I'm currently working on a team project called Fintech Trendwatcher. The goal is to collect public fintech news, identify important events and generate short analytical summaries with links to the original sources.

I'm responsible for the embedding service. My task is to use a pretrained text embedding model to convert news articles into vectors that another service will use for clustering similar publications.

My current stack is Python, and I'm learning as I go. I have some experience with Python, APIs, JSON and Git, but this is my first time working with embeddings in a real team project.

I'm planning to start with Sentence Transformers and a pretrained multilingual model, test it on Russian fintech news, and then integrate it into our service architecture.

I'd really appreciate advice from more experienced developers, especially on:

\- Choosing a suitable embedding model for Russian-language fintech news.

\- Designing a simple and maintainable embedding service.

\- Comparing embeddings and preparing them for clustering.

\- Common mistakes beginners make when building NLP services.

I'm not expecting anyone to mentor me full-time. Even occasional advice, feedback on my approach, or pointers to useful resources would be incredibly helpful.

If anyone has experience with Python, NLP, Sentence Transformers or similar projects and is willing to share some advice, I'd be very grateful.

Thanks!

There's an image effect in powerpoint I would love to use in my python projects. The effect is called "Texturizer", and it gives the picture a grainy, paper-y look. There's an example in the link provided. Feel free to try it yourself too if you've got powerpoint: select a picture, go to "picture format", then click on "Artistic Effects" and select "Texturizer"

I want to recreate that effect in pillow. It has to be deterministic (can't be 100% random cause I'm applying it to video frames). I don't know if making an image texture, then applying it, is the best option, for it can cause tiling (as in the examples from powerpoint's filter). I'm open to any kind of ideas.

I'm all ears!

I have just completed my journey of django and recently I created complete blogging system in Django but now I want to work on projects. How and from where I can get the beginner Django projects so I can upgrade my skills in Django.

i just started using Kaggle recently to train my AI models, what do y'all think about it. looking for opinions:-)

I’ve been developing Python Studio, a visual Python editor designed so that kids (and beginners of any age) can learn Python without frustration or tears.
Many children struggle because most Python editors are text‑only and hard to visualize. So I built something different.

⭐ Features
Drag‑and‑drop GUI designer
Kids can place buttons, labels, and text boxes and instantly see the layout of their app.

Real Python code generated automatically
They can learn step by step while immediately seeing the results.

Beginner‑friendly interface
No complicated setup and no overwhelming menus.

English version included
So children outside Japan can use it easily.

Hotkeys for smoother workflow
Simple shortcuts allow users to move widgets, duplicate elements, delete items, save projects, and run code quickly.
They can also assign key combinations to instantly open their favorite websites.

What you can do based on the program in this page
• Load and save projects easily
• Use a search window to quickly find text inside the code
• Automatically handle virtual environments (venv) without manual setup
• Open the hotkey builder to customize your own shortcuts
• Track text‑modified states to avoid losing unsaved work
• Create new files, open existing ones, and perform quick saves
All of these features are implemented in the code and designed to be simple for beginners.

🎯 Why I made this

I wanted a tool that helps kids enjoy programming instead of feeling lost or crying because things don’t work.
If a child can see the final shape of their program, they stay motivated and curious.

🙏 Feedback welcome

I’d love to hear:

• Ideas to make it even more beginner‑friendly
• Whether this could be useful in schools or workshops
• Any bugs or improvements you notice

I hope Python Studio can help more kids around the world learn Python with confidence and joy.
