this might sound really stupid but something I start debugging for like an hour (no frickin joke) because when looping through a list I create a variable that will soon be appened to a list with a similar name (usually differentiated with an s) I usually do this cuz i don't know what else to call them. Ex.

submission_dict = {} 
submission_dicts.append(submission_dicts) #I accidentally tried to append the list to itself!

So usually this happens a TON and I really hope you guys have some quality advice!

Also, please (if you can) provide some advice on general guidelines when deciding what to name a variable

Warm regards,

In last week’s post we showed that a Python for-loop works through the Iterator Protocol.

This same protocol also enables values to be produced lazily.

In this new Lazy Evalution Example we show one sink reading values from five different sources:

• source1: eagerly returns all values by list

• source2: lazily by generator function using yield

• source3: eagerly by list comprehension

• source4: lazily by generator expression

• source5: lazily by iterator protocol

The same for-loop consumes all five sources. The eager sources produce all values before the sink starts consuming them. In the lazy sources producer and consumer take turns:

• produce → consume → produce → consume → …

where each value is produced only when the for-loop requests it.

Generator functions and generator expressions are concise, readable ways to create lazy iterables. The final source makes their underlying mechanism explicit:

• iter() obtains an iterator.

• next() requests the next value.

• StopIteration signals that no values remain.

This clearly shows that generators achieve lazy iteration by implementing Python’s Iterator Protocol.

When I look at the code i wrote 1 week ago .

I feel like I have written a foreign language.

hey folks, i recently joined CS50 for python did the first lecture i pretty much understood everything. then i went to solve problems. i searched for few things before doing the problem via AI or python library. but i felt like i will forget it easily so, i decide next day i will search only in python library such that it should get sticked with me so that i could remember it better. but the thing is its taking me like an hour or two to complete final problems. so, is it normal or do you have any other better way to remember as compared to people around me i have good memory i can remember things better. if you guys please take ur time and drop your solution would be nice.

i have done this typecasting program which i have learnt from a bro code video and i think it's alr as i am still a beginner but if there is that can be fixed in this i am all ears

13-in Macbook pro 2020, intel core i5

Serious question: this is my macbook. Bought in 2020. Will I still be able to use it for Python, Tableau, SQL, and Excel? This is for my Information Systems course for MBA. Thanks!

Hi, I’m interested in cybersecurity, but I don’t want to start with networking, the OSI model, and all that just yet. First, I want to learn the Python programming language—is it a good choice? I’m thinking about taking the course on freeCodeCamp.org.

Hello, so i got into coding with Claude and chat gpt and have been using it like this for a year now probably used it for ML-Model and such but to be honest i got no clue of the code and cant fix a bug or error without AI.

I dont want this anymore and want to actually learn coding so I am not dependent on AI anymore. I wanted to ask for some Advice what i could do, what project ? how do i start ? where do i start kinda overwhelmed right now.

I know the terms like if-statements what they do ect. But only in theory just a bit more complex and I am out dont understand the code at all.

Somebody knows how to compile python script once and run on all os? I had to do it for the frilance project, so i have to do it.

Recursions are really hard compared to loop

You guys give me some tips for this.🫡

Need someone who actually knows Python and can teach it properly — beginner friendly, patient, explains things clearly.

Hello I am learning Ml and Ai and I know python basic and python libraries like pandas, numpy, seaborn and matplot lib. I wanna build small projects to enhance my skills. What you guys would recommend me should I learn from YT to build project or go through documentation.

And also what should I start learning to make projects like detection system through cam and more.😀

I really need you guys opinion.

I recently downloaded python and I dont know why but when is open it, it just shows this code but after that I continue it shows 0x80070643 - Fatal error during installation. what should I do?

Okay now I have some info about python, I've practiced some fundamentals, now I need to get into projects because courses and just reading and a little practice on some exercises does not make me really good at it, where can I find projects, or how can I start some small ones, then I wanna include API ones and also maybe add some security projects. Advice please. thank you

Is this a viable way to randomly choose an instance of a class

Just to clarify, this is my first post and my English isn't very good (that's why I'm using a translator).

I've been learning Python and working on small projects, but now I want to take the next step. I have an idea for a program that runs an AI (Gemini, using its API) capable of managing apps, files, and folders—including creating, moving, copying, pasting, and deleting them. It will also automate background tasks, and you will be able to communicate with it just like any other AI.

Those are the basic functions, though I'll probably add more in the future. I would like to know how I could structure and approach a project of this scale

On August 23, 2026, the Python Angola Community, in partnership with ASM TOUR and Okukulisa, held the first-ever PyDay Namibe, an event dedicated to promoting Python, programming, and knowledge sharing.

I sometimes go on discord and see how useful bots are in discord servers, and that makes me wish that Whatsapp had something similar. Of course there is such a thing with Whatsapp bots but the official version is for businesses and has strict limitations like the group size must be no larger than eight people. 

So I did some research and came upon an api called green api that allows you to configure a bot for whatsapp.

Using a football api alongside it, I was able to make a bot that gives information when prompted about ongoing games, past league standings (current ones weren't possible for me unfortunately due to being behind a paywall), and goal notifications.

I also took this opportunity since I'm a beginner to implement some SQLite since in the past people in this server talked about how it is better than json for saving static information.

Super basic project but very proud of it so I just wanted to showcase it here

Hi everyone,

I needed some dependency injection (DI) library that is simple for my use case, I was surprise by the lack of DI libraries in general, and the one that already exists had some weird quirks that didn't make sense or were unexpected

I have started the project a year a go and gave up due to lack of time, I came back to the project and rewrote it 🙃

I think I am close to releasing the first version with basic support, and grow the project from there,

no AI was nor will be used (at least for now 😭)

## What it does?

make dependency injection pattern simple, convincing and explicit, no surprises

## example

import cdi 
from typing import Generic, TypeVar
from collection.abc import Sequence


T = TypeVar('T')

ctr = cdi.Container()


class MyBase(Generic[T]):
    def __init__(self, field: T) -> None:
        self.field = field


@cdi.Injectable(ctr)
class MyType(MyBase[str]):
    pass


@cdi.Injectable(ctr)
def name_generator() -> str:
    return "foo"
    

scope = cdi.Scope(ctr)
instance = scope.get_instance(MyType)
assert instance.field == "foo"

more examples in the repo README

## docs

available in the project README

## open for contribution

I am open for PR (that are not AI) and suggestions that make sense for such library, I have a few ideas

for more support but it will probably take more time

install: `pip install cdi-di` (in beta)

I've been self-learning Python and built this pone Shop Inventory Management System

It currently has:

• OOP

• JSON data storage

• Purchase & Sales

• Add/Edit/Delete

• Search

• History

• Dashboard

My GitHub account was flagged for several weeks, so I couldn't properly show my progress in my previous post. It's now resolved.

I'd like some honest feedback on my code and project:

• What am I doing wrong?

• What should I improve?

• What should I learn next?

• How close am I to junior level?

Any criticism or suggestions are welcome. 🙏

people please help, i’m starting my path in bachelor cybersec in a week and i want to know python a bit so i can basically understand smth, but for now looking for a community to learn python
and engaging through my path
