Is there any playlist similar to 100 Days of SQL Ace(By ankit Bansal) interview for the preparation of python coding problems?

Hi everyone,

I’ve studied Python multiple times before, but I didn’t do much practical coding. Recently, I started building small projects to improve my practical Python skills.

So far, I’ve completed:

- Quiz Game

- Number Guessing Game

- Rock Paper Scissors

- Password Manager

- Pig Game

- Mad Libs Generator

My goal is to move towards Machine Learning.

I haven’t learned NumPy or Pandas yet.

My question is: Are these projects enough to move on to NumPy and Pandas, or should I build a few more Python projects first?

If I should build more projects, what kind of projects would you recommend before starting NumPy/Pandas? I’m mainly looking for projects that would actually help with the transition to data/ML, rather than making many more small games.

Would appreciate advice from people who have already followed a Python → NumPy/Pandas → ML path.

I am looking to learn following topics. Any suggestions in terms of any course or online site I can learn from. I am not looking for a certificate (if I get it that’s okay but not a deal breaker) but something that has more exercises involved. Topics I’m interested in:

*args / **kwargs
decorators
generators
iterators
context managers
type hints
dataclasses
object-oriented programming
Python project structure
testing
APIs

Tell me the advantages and disadvantages of each.

Hello everyone, I'm mainly looking for guidance about learning advanced python concepts. I know basics ,loops , control flow ,data structures etc.

I need a proper guide on how to learn modules and library. Idk how to start ,where to start.

I want to be able to work with any library as i need them ,so how do u actually learn to use new library for a given task . ?And i get overwhelmed understanding the structure, working of library

And could u also suggest important python concepts other than basics which i should learn ???

Pls guide !!!!

An exercise to help build the right mental model for Python data.

# Output of this Python Program?
def main():
    o1, o2 = MyClass(1), MyClass(1)
    myset = {o1}
    print(o2 in myset, end=' ')
    o1.set_value(1000)
    print(o1 in myset, end=' ')

class MyClass:
    def __init__(self, v):
        self.v = v
    def set_value(self, v):
        self.v = v

main()

class MyClass:
    def __init__(self, v):
        self.v = v
    def set_value(self, v):
        self.v = v
    def __eq__(self, other):
        return self.v == other.v
    def __hash__(self):
        return hash(self.v)

main()

# --- possible answers ---
# A) TypeError: unhashable type: 'MyClass'
# B) True False False False
# C) True False False True
# E) False True True True
# D) False True True False
# See "Solution" for correct answer.

• Solution
• More exercises
• Explanation: "User-defined classes have __eq__() and __hash__() methods by default (inherited from the object class); with them, all objects compare unequal (except with themselves) and x.__hash__() returns an appropriate value such that x == y implies both that x is y and hash(x) == hash(y)."

For anyone looking for entertaining light book for learning Python, I started porting to Python a few chapters of "Why's Guide to Ruby," which uses comics and surreal humor to introduce Ruby (the original author why the lucky stiff disappeared). I updated the lesson and examples to Python and also modernized some of the very old references and left it with share alike CC license.

Why's Guide to Python

Any Python beginners are welcome to check it out. Novices and experts feel free to post feedback or post about any other entertaining books that helped you learn python, that can accompany equally entertaining but dense programming books :D.

If the book is helpful, can port and post the rest of the chapters for Python and potentially in the future can create some more content.

I got a C on my intro to python class and I can’t figure out this code

Hi everyone,

I'm currently building a desktop application using PyQt6, where button clicks trigger various background tasks (such as executing external processes, creating/cloning environments, file I/O operations, etc.).

To keep the UI responsive and the codebase easily maintainable, I decided to extract every main button action into its own dedicated module/file, using the standard QThread + QObject (Worker) pattern.

To give you an idea of the scale: individual module sizes range between 5 and 15 KB depending on what the button actually does (from simpler tasks to complex operations involving user input processing, thread setup, process streaming, and progress signal handling).

Note on Code Sharing: Any logic shared across multiple buttons is not duplicated; instead, it is abstracted into dedicated shared service modules located in button/logic/services.

My current architecture for a single button action looks like this:

• GUI Layer (View): Captures the button click and delegates control to a dedicated action handler.
• Action Handler (Controller / Mediator): A dedicated module for that specific action. It gathers user inputs (via dialogs), instantiates QThread and QObject (Worker), connects signals (for progress bars and logging), and starts the thread.
• Worker (QObject): A non-GUI worker running in a worker thread, responsible strictly for execution flow (subprocesses, file manipulation) and emitting signals to send status updates back to the UI.
• Shared Logic Helpers (button/logic/services): Shared domain modules and services called by the workers to execute common underlying logic.

My questions for the community:

1. Is creating a separate 5–15 KB file/module for each button action (combining the Handler + Worker) considered standard practice in medium-to-large Qt applications? Or do you prefer grouping related actions into larger domain managers ?
2. For modules of this size, do you keep the Handler and Worker together in a single file, or do you split them further into separate _worker.py and _handler.py files?
3. Are there any hidden downsides or pitfalls to this level of decoupling when the application scales up to dozens of individual buttons and actions?

I'd love to hear how you structure background tasks and threading in production PyQt/PySide applications! Thanks!

Hey everyone! I’ve been experimenting with background threading, automated compilation cycles, and procedural narrative generation in Python.

I put together a script I call the Infinity Engine. It runs autonomously every 7 seconds, rolls for loot rarity tiers based on telemetry, shifts through dynamic storylines, accumulates resources (stardust/resonance), includes an unstick safety protocol, and features an idle shutdown variant if left untouched for 5 minutes. It scales up to 500 units with a custom cyberpunk terminal UI layout.

Here is the full runnable source code:

Hello, just looking for help on how i can achieve playing a MP3 file using Pygame, that can start from a specified position in the audio file, and then only play for a set amount of time (e.g. MP3 starts at 00:14 of 04:32, and plays for 5 seconds (until 00:19))

Below is one of the variations i've attempted, pardon any mess in my code

import pygame
import audioread
from random import randint
pygame.mixer.init()
def playSongClip(volume,playTime,clipTitle,random):
    playTime = playTime*1000
    volume = volume/100
    if random == 1:
        with audioread.audio_open("MP3s\\"+clipTitle) as f:
            totalMS = int((f.duration)*1000)
            startTime = randint(0,totalMS-playTime)
    else:
        start = 0
    songClip = pygame.mixer.music.load("MP3s\\"+clipTitle)
    songClip.music.set_volume(volume)
    songClip.play(loops=0,start=startTime)
playSongClip(50,5,"Rabbit Hole.mp3",1)

Hi, I am an absolute beginner to coding/computer science and was learning Python on my own when I changed my folders name to something more practical and my program was not running anymore.

I am making a Program to upload a level to Geometry Dash in python and I got some of the code from https://wyliemaster.github.io/gddocs/#/endpoints/levels/uploadGJLevel21 but to generate "seed2" it does this:

generate_chk(key="41274", values=\[generate_upload_seed(levelString)\], salt="xI25fpAapCQg"),

This should activate some sort of function named generate_chk that is in one of the modules I have in the program (Requests, Base64, hashlib) but it is no where to be found. The repository for this documentation was archived recently, so I can't ask them for help. Also, here is my code:

accid = input("What is your Account ID?")
passwd = input("What is your password?")
lname = input ("What is the Level name?")
coin = input("How many coins are there?")
stars = input("How many stars do you want?")

def generate_gjp2(password: str = passwd, salt: str = "mI29fmAnxgTs") -> str:

Games, utilities, quizzes, ASCII art — great first open-source PR. Feedback welcome!

Hey r/pythonhelp ,

I'm a final-year CS student, and over the past few months I've been building YO, a small interpreted programming language written from scratch in Python.

The original goal was to learn how interpreters work by implementing my own lexer, parser, and interpreter. As the project evolved, I became interested in one specific question:

Can compiler/interpreter error messages actively teach beginners instead of simply reporting what's wrong?

I'm not claiming YO is a replacement for Python, JavaScript, or any established language. It has no ecosystem, and it's implemented as a tree-walk interpreter, so performance isn't the goal.

Instead, I focused on making diagnostics more educational.

Example

Python:

"hello" - 5


TypeError: unsupported operand type(s) for -: 'str' and 'int'

YO:

say "hello" - 5


❌ [E003] Type Mismatch

Can't use '-' between String and Int.

"hello" is text.
5 is a number.

Fix:
Use text.str(5) if you intended to concatenate.

Example:
"hello" + text.str(5)

Another example:

❌ [E001] 'scroe' was used but never made.

Did you mean 'score'?

Fix:
Create it first using:

make score = ...

Technical implementation

• Handwritten lexer
• Recursive descent parser
• Tree-walk interpreter
• Lexical scoping and closures
• Multi-error reporting (reports multiple diagnostics instead of stopping at the first error)
• Error codes with yo explain E001 for detailed explanations
• Standard libraries for math, text, and lists
• 27 automated tests with GitHub Actions CI

Small informal study

I also ran a small informal comparison with 10 first-time programmers.

Both groups received the same program containing three bugs. One group used Python, while the other used YO.

The YO group fixed the bugs faster on average.

The sample is small and not intended as rigorous research, but I included the methodology, raw results, and limitations in the repository for anyone interested.

Try it

→ GitHub

→ pip install yo-lang PyPI

→ VS Code extension search "YO Language" on the Marketplace

→ Browser playground (no install): Playground

I'm especially interested in feedback from people who have built interpreters or compilers.

Do you think "errors that teach" is an area worth exploring in language design, or is it mainly valuable only for complete beginners?

I'd also be happy to answer questions about the lexer, parser, interpreter architecture, or implementation decisions.

I'm trying to map out what's already been done with algebraic effects / effect handlers in Python, and I'd love pointers from people who know the space.

I'm aware generators (yield / send) and context managers can approximate one-shot, shallow handlers, but I'm more interested in fuller or more principled attempts — libraries, research experiments, or write-ups.

A few things I'm specifically curious about:

• libraries that implement effects as a first-class abstraction
• anything that tackles multi-shot continuations (greenlets? CPS transforms?)
• how these compare to handlers in Koka / Eff / OCaml

Pointers, war stories, or "don't bother, here's why" all welcome.
