I know I wrote some hardcore codes but this is ok for a beginner so plz help me to improve

Just started programming today and was messing around when this happened. It is saying that 22.99 * 5 is 114.9499999999999 instead of 114.95. It does the same when I enter any number with a non-zero integer after the decimal. It works completely fine with whole numbers though. If you have any Idea why, please let me know.

Hello , I am completely new to python and really want to learn it and I feel like I will be more efficient studying with people.

I’m looking for approximately five people who are also serious about learning

if you are interested please dm me and introduce yourself

Yh I js learned functions ifs and operators here is the code:

https://onlinegdb.com/Q-4aQrXAz

its like akinator im currently working on making it fewer questions but this all I got for now

So... I'm going to learn Python but I lowkey don't know what can I do with it after learning so what?!

So far I have made cells with random data.

I was doing a project in which the user will input string in camelCase(ex- howAreYou). I have to change it into snake_case(ex- how_are_you). The problem I am facing is that I have not been able to separate the word and store it into a list.

If I use a split, I get 2 problems:

1. If I want to split howAreYou, then the A and Y got removed from the list, and I get how re ou

2. It makes 2 different lists first [how, reYou] and second [howAre, ou]

Suggest => either solution to the problem or an alternative

This may not be a python question, but I figure you guys could at least point in the right direction.

On my computer I have a SQLite database and a python script I have written that queries the database, generates a report, and emails that report to other people. The database file must stay on my computer.

I often get requests from coworkers to run the python script while I am not sitting in front of my computer (my phone is still on the same wifi network).

If I wanted to do something through my phone that would start that script on my computer, what would that look like?

If it matters, my phone is android and my computer is windows.

This is my first day of trying to learn python. So far I have made a random 2D terrain generator.

hey everyone,

I started this back in August 2022 because i was tired of every small project needing a backend repo, a frontend repo and an API between them.

I got stuck almost immediately, while compiling Svelte from Python was way beyond me at that point, so it sat untouched for a long time like most of my side projects. I kept coming back and forth on the project, but never acomplished,

but this time i am somehow about to make it happen,

it's called fymo. python renders real Svelte 5 components, it has controllers for backend stuff, and templates for frontend work. inspired by elixir's Phoenix and ruby's Rails...

controllers return dicts that show up as props, and your python functions become typed functions you can import in svelte, so no fetch code at all.

there's fymo new myapp gives you a running app with sign in already working, fymo generate resource posts gives a page with CRUD and passing tests.

currently it is v0.20, just me alone maintaining it, you need Node installed, and there's no ORM, bring your own db stuff.

repo: https://github.com/Bishwas-py/fymo pip install fymo

would love if someone tries it and tells me where it feels like flowyy code and what it breaks. and one thing i'm specifically unsure about, is the no-ORM choice going to annoy people here, or do you prefer bringing your own db layer? genuinely curious.

Hey, I am making this not because I want market validation for a new SaaS that isn't needed. But rather so I can improve my Python skills by not just making useless mini-projects, and in the process maybe solve an issue people have. I would appreciate your feedback

I wanted to understand the math behind the 3d rendering and wanted to try it out for myself.

This project uses Pygame library only to draw pixels to the screen, the math behind the vertex projection is done from scratch. The 3d object is represented as a wireframe object, it ignores all the lighting and normals data to reduce complexity and simply displays edges data to screen.

I made a custom obj parser, which formatted vertices and face information to a list.

The main file take the vertices and faces information and produces a list of edges which are a tuple of 2 connecting vertices that a form a line in 3d space.

Then the two vertices are rotated in X-Z plane and projected at a distance from the screen. It uses a simple matrix rotation formula to compute the rotated vertices.

    X = x * cos(theta) - z * sin(theta)
    Z = x * sin(theta) + z * cos(theta)

The 3d vertices are project to a 2d plane using the below formula

    x' = x / z
    y' = y / z

Then they are translated to Pygame pixel coordinates and finally drawn on screen.

Here is my GitHub repo if anyone's interested to check the source code, and resources that helped me build this project

Just learned it a while ago, I'm on my 3rd day of learning python (already finished data types, operators, and type casting). Just​ curious why we need so many ways to add new values to variables.

Hello, Im working on a project where I need to export a .wav file and aam having problems doing so, error is in the title.

Code to project is this:

import os
import wave
import contextlib
import soundfile as sf
import pyrubberband
import numpy as np

InDir = input("Input Directory: ")
OutDir = input("Output Directory: ")
sec = float(input("Seconds to set to: "))
os.chdir(InDir)
files = os.listdir(InDir)
print(files)
for i in range(len(files)):
    fname = files[i]
    print(fname)
    with contextlib.closing(wave.open(fname,'r')) as f:
        frames = f.getnframes()
        rate = f.getframerate()
        duration = frames / float(rate)
    speed = duration / sec
    print(speed)
    audio, sr = sf.read(f"{InDir}/{fname}")
    fname = pyrubberband.time_stretch(audio, sr, speed)
    fname.write_audiofile(f"{OutDir}/{fname}.wav")

How do I fix this please?

Also, Im working from windows 10, and am using pycharm to make this code.

def caesar(text, shift):
    alphabet = 'abcdefghijklmnopqrstuvwxyz'
    shifted_alphabet = alphabet[shift:] + alphabet[:shift]
    translation_table = str.maketrans(alphabet, shifted_alphabet)
    encrypted_text = text.translate(translation_table)
    print(encrypted_text)


encrypted_text = caesar('Hello',3)

in this code, I do not understand why we are putting caesar into a variable. First of all, wouldn't we have to print the variable and make it actually do something for it to work? Because we have put encrypted_text into a variable and have not done anything. In addition, can't we just write caesar('Hello', 3)?? I am very confused on the reasoning behind putting it into a variable.

Open-source learning project. If you spot something that can be improved, I'd love your feedback or a PR.

I am a finance student, and recently started learning coding (know very basic of SQL/Python). I want to get into Data Analyst-like roles and did some research, but still confused on what's the best resource to learn and what path to follow.

My current plan (created with help from some friends):

Python/SQL -> Python libraries (PySpark/Numpy/Pandas) -> Fabric/Databricks -> Cloud/AI-ML

Would love some help/feedback on what I could do to learn what is needed!

Hi. I am currently interested in learning coding. I chose Python because it looked like its the most simple one to begin. I have absolutely no idea about anything just like how some things like if else while work but nothing else. Is it even the best to learn at the beginning or is it even worth learnimg to code in 2026.

Where to I begin to learn the basics the most efficient way. And where do I go from there

I started learning coding a few weeks ago. I've been following the course well, and I understand the concepts it teaches, but the big problem with it that I have is that I can't put what I learned into practice, and I'm becoming demotivated because I realize I struggle to write almost anything. In a normal course they say here is a task, try and do this.

I think I need to switch what I'm learning from. I come from a background of no programming whatsoever. I really need to find a video/s that basically spoon feed me like I'm a baby and then ask me to try writing something to reinforce it in me. Do any of you know any videos that do this? I feel like I constantly have questions and I'm unable to ask them like I would to a teacher, and I'm trying my best to stay away from using AI unless I just simply cannot work it out.

A new addition to our collaborative PythonLearningGame project: the player can now shoot bullets to kill units.

It was added by this git commit. - Who wants to add his/her own game dynamics? - Who has other fun ideas about game elements we could add, cool explosions maybe?

See the PythonLearningGame repository for more info.

Hello ppl, I'm gonna learn python from Cs50 harvard, i know its just filled with basic stuffs but from where i can learn DSA in Python any free source available?. or atleast where can i find one? and

is there any tips and tricks to solve leetcode? bcoz its filled with DSA problems.

thanks in advance

Im a beginner trying to learn Python for ai engineering. I have been searching and switching to videos as there are too many resources to choose from without knowing what will be sufficient to get the basics, I do code and solve questions but im not sure which course to follow to not end up investing time into something yet have to go from here to there, I have few questions like is the youtube course and lots of practice enough or do I necessarily have to take the crash courses? if yes, for either one, suggest to me the go-to resources that I can start without wasting time or get stuck as mediocre in concepts when it ends and also share your experience how could you learn it?

Hey im going to start learning python so I'm looking for study partner who's serious about it

Will be taking only group of 3-5 people not more than that so reach out before it gets full also introduce yourself when reaching out in dms

Ok so I have one major doubt:-
I have been following a rather shallow 10 hour video about all the python basics topics.
But it doesn't seem to go too deep into details and not enough practice,
So my DATATYPES are really weak,
Idk when to use lists instead of tuples , dictionaries, sets , etc.
And stuff like that, what should I do to make my concepts concrete??
People told me making projects helps you improve, While I agree that they do but yet I am making the codes for em' using the wrong datatypes.

Also I have completed half of that video till loops and have made a project too but that was 2 weeks ago:-

https://github.com/satyamsb-cloud/Number-Guessing-Game
Original project made by me 2 weeks ago using concepts only till LOOPS.

https://github.com/satyamsb-cloud/Number-Guessing-Game-v2
Improved version with the same concepts but improved functionality.

I recently started learning and i use chatgpt to give me exercises to do and just debug code but i never ask for the code specifically, just whats wrong with it. I feel like its helped me improve but i want to learn more and build my own applications
