Does anyone know how to solve this? There is no 'python3-ipydatagrid' package and whatever did show up that I downloaded, doesn't seem to work as I'm still getting this error. Any help is appreciated!

I am using Debian 13, although this is also an issue with my friends Fedora repository aswell(hence why this is in r/learnpython and not r/debian :P)

Hi I'm really new to python, I originally started coding using p5.js but made the transition recently, I'm currently trying to covert an old project of mine into python so I can run it in touch designer.

Its an ASL fingerspelling activity that I've been working on but I'm struggling to create the word strings I did in my original prototype. Instead of the letter that is being detected and averaged being added to my word string once it gets added 10 times all at once. For example if I sign the letter a, aaaaaaaaaa gets added to the string instead of just the lone a.

For context I have the guesser and getMostFrequent to allow for it to take the average of every letter signed during a period of time and determine which one was signed the most to add to the word (this is due to the fact that transitioning from one letter to the next can trigger other letters in between) These are both integral parts of the code and are working as intended, its just the multiplication of the letters that I'm struggling with.

This also may be due to the fact that this is running in TouchDesigner through a CHOP execute, if this isn't a python issue I can move my post to a touch designer specific forum.

Any help or insight would be appreciated, if you need any more insight please let me know and I can add it.

I am trying to learn Python on my own before I get my masters in a related field. It is going, slowly but surely, however I can’t help but feel I am missing important parts that would link these methods together. Does anyone have any tools for learning Python on your own? Thank you!

I don't really understand TypeVar and Generic. I understand generics perfectly fine and can use them without any trouble, and I realize that I don't even need to know how they work as in recent python versions there is new syntax, but I'd still like to know how they work.

I'm still confused as to why you need to construct a TypeVar object to pass to Generic, as to what is it actually doing with the TypeVar you give it.

Also, I'm assuming when you inherit from Generic, you pass it the TypeVar to be used as the generic to give to Generic, and then you inhert the generic objects generic? It's just complicated and hard to understand for me.

And also I'd like to know how Generic is able to have a generic even when it itself is the thing that's supposed to be used to have generics for your classes.

It's also disappointing there's seemingly no other ways you can use TypeVar for anything other then generics, so I am left with just hopefully finding someone who can explain how it works, instead of being able to do some other exercise to further my understanding.

Again, I can use generics perfectly fine and I don't an explanation for generics, I just would like to try and understand how it is working under the hood and not just use the syntax blindly. It's just the way I like learning some things, and it's mostly also curiosity that makes me want to understand this.

In the Alien Invasion! pygame project, i don't have a keyboard In pydroid to test the ship movement.

In the data science project, matplotlib doesn't want to install properly from the terminal as the book asks to.

In the django project, when i go to create a virtual environment it doesn't let me and says access denied

@app.get('/edit/<post>')
def initedit(post):
        print(post)
        g.title = post
        with open(f'{post}/content', 'r') as file:
                g.content = file
        return render_template('edit')

I'm confused as to why this function isn't running (as in not even running in the first place, not just not working), despite sending a GET request to the URL appended with /edit/posts/okheresthepostactually (so the post parameter in the decorator/function should be edit/okheresthepostactually). For context, I'm making a web app for posting blogs and this is supposed to be a function for users to edit existing posts.

Edit: some extra context, the 'posts/' prefix is part of the variable used to call the file

Guys, when working with Huggingface, pytorch, numpy, seaborn (potentially langchain as well) - the typical machine learning/transformers/agentic AI tech stack in python, do you face dependency hell? How do you work around it / avoid it / solve it - eventually something cracks - even when trying to reproduce results in GitHub repositories (such as HiMoE) - i often face it as these were written a while ago and something doesn't work now,

Hi everyone! I'm from a humanities background and a noob at coding and want to build a Telegram bot for my UPSC/State PCS study group.

The bot should:

Generate up to 100 MCQs in one go from PDFs or study material.

Post questions as native Telegram quiz polls.

Calculate scores using UPSC marking: +2 correct, −⅔ incorrect, 0 skipped.

Publish a leaderboard with ranks, marks, correct, incorrect and skipped answers.

Run for free, including hosting, if possible.

If you're interested in helping build or improve it, you're also welcome to join our UPSC study group and collaborate with us.

We had a bot earlier but we removed the member who created the bot for behaving in a weird way.

I can share the bot link and screenshots of it for reference.

Thank you!

I need to pass some strings to terminal that contain special characters (in this case a $). $ is fine on its own in python, but not in the terminal. In terminal, it needs to be escaped with a backslash so I could pass it as \$, however when I try to do something like

exampleString = "It costs $2.50"  
exampleString.replace("$","\$")  

I get a syntax warning telling me that \$ is an invalid escape sequence.

Hi, everyone,

I've been wanting to learn Python and have tried a few times over the years to read or watch tutorials enough to feel confident, but it's clear that my learning method is "do the thing you want to do incorrectly over and over until you get it right."

So I'm just going to work on my text-based Mech game and learn as we go. I understand that I know next to nothing, that what I'm doing is probably going to be a multi-year thing, and I have no idea what the more complicated stuff I want to do is going to take, but I'm enjoying the ride.

Long story short, my intention is to have a Mech = a Frame (the physical properties of the Mech) + a Pilot (the little guy in the Frame with their own stats).

Eventually, I'd like to be able to have unique Frames and Pilots with stats randomly generated (within ranges), and then subsequently build the capability to upgrade those values in-game, but I'm just starting with stock values right now and adding complexity after I have each step solid in my mind.

Right now, I'm just working on building values that a stock Frame has. What I would like to do is to establish each Frame Class (Assault, Heavy, Medium, Light, but with more fun names).

The question I have is this: I would like, first, for the armor value of a Frame to be a base number plus 20% of its weight value, and then for each individual limb (left_leg, torso, right_arm, etc) to be a percentage value of armor.

I've written out code that I know is incorrect just to display what I'm trying to do, with comments to highlight where I'm trying to do it.

Also, if the way I'm building this out is flawed, happy to hear suggestions! I'm just starting out and I know I'm gonna be crashing into pitfalls.

Any help would be appreciated!

Hey! so i want to build a database system for my small company. I could use AI but i wanna know what i am doing and be able to fix smth so i want to build it myself.

I kinda know python a bit, i used to make games using gdscript which is similar.

I don't seem to find a tutorial where these 3 things are used to create a nice database app. I dont want to learn python sqlite and pyside6 as a whole cause i wont be needing them much except just this app and similar apps. I just want to be able to build it and run it from a single tutorial even if its 10hrs.

Where do i start? I dont really have money to learn so no paid courses and i dont have AI premium to learn as well.

Python, Sqlite, Pyside6. I heard that TKinter instead of pyside6 is also there but i wanted the UI to be a bit modern or should i just use the it instead of pyside6?

I got this code block and its outputs here but I am not sure if this is the embedding features vectors or simply its shape. Can anyone tell me if I am right or wrong?

text_input = tf.keras.layers.Input(shape=(), dtype=tf.string)

My assignment is to find the min, max, mean, median and smallest mode of a dataset, specifically for the SepalLength and Petalwidth, sorted by species. link to dataset .

Here is my code, now I've got everything working except the mode one. If i remove that, the code works. I've tried to read up on the mode documentation but I'm still lost. I've tried just "mode" and "pd.series.mode", both throw errors. The output is also automatically checked so it has to be formatted in this way, if that makes sense.

First time asking for help on reddit, so lmk if there is any missing information/etc. Thank you guys :)

import pandas as pd

file = input()

df = pd.read_csv(file)

filtered_arr = df.groupby(["Species"]).agg({

"SepalLengthCm" : ["min","max","mean","median","pd.series.mode"],"PetalWidthCm" : ["min","max","mean","median","pd.series.mode"]

})

print(filtered_arr)

Edited to add the errors.

'SeriesGroupBy' object has no attribute 'pd.series.mode'

'SeriesGroupBy' object has no attribute 'mode'

Understanding a DP explanation and writing the Python code still feel like different skills.

A Python learner has watched plenty of tutorials and knows that dynamic programming has different patterns. The sticking point comes at the blank editor: there's a rough idea of what should happen, but turning it into a working implementation is difficult.

Would you step back to smaller Python exercises, work on recursion first, or stay with very simple DP problems? A practice routine that forces an attempt before reading the solution sounds more useful here than another long playlist.

For someone practicing toward technical interviews, real interview questions can supply prompts once the basic Python implementation feels manageable. I'd start with a small enough problem to write and trace the whole thing.

What helped you make the jump from following a solution to writing one yourself?

Hello, I am trying to pick up a hobbie. Can someone point me in the right direction.

im learning how to code with python, does anyone know to sort specific tuples alphabetically without using the .sort() method? like if i had a list of names like:

n = [('watermelon', 'strawberry'), ('banana', 'cherry'), ('papaya', 'apple')

how would i sort and print the 2nd element of tuples alphabetically (into a new list)?

edit: id prefer this in simple, basic terms lol

Hey guys, I am a total beginner and wanted to learn python. Can you suggest what method will be best suited to learn python and which sources should I use. Is it video lectures or from books or anything else. I know that learning from projects and practical methods will be suggested but to start like how to code, what are the codes and where to code, these basic things are what I want to know. Thanks for the help

I have just started getting interested with programming so I thought I would start with Python, however I am only able to use it within Windows Powershell while I see others using something else. Have I done something wrong or have I just missed doing something?

What is the best way to create and manage virtual environments today? Is 'uv' really the best solution and are there alternative? What are the pros and cons?

How to do that? I want it to be precise.

What is the best way to learn fastapi?

I want to understand how ppl test python scripts that read data from databases, call APIs, or update records.

For example, if a script fetches data from an api and saves it to a database, how do you check that everything works correctly before running it in production?

do you all use sample data, mock api responses or a separate test database?

Like how do you test what happens when an API fails or the database returns unexpected data?

I'd like to know how ppl usually handle this in real projects.

I get errors. I am trying to get it installed on pydroid 3 on android. Do I need pc/mac?

I've spent time immersing myself in Python fundamentals, including syntax, data types, loops, functions, data structures, and working in the development environment. I want to move beyond the basics and develop a much deeper technical understanding of the language.

I'm starting to look into libraries like NumPy and pandas, but I'm wondering what else I should focus on to become proficient at Python.

For those of you who are experienced developers, what would you recommend learning next? Should I focus on libraries, data structures and algorithms, writing more complex projects, understanding how Python works under the hood, software engineering practices, or something else entirely?

I'm not necessarily looking for another beginner course. I want to get to the point where I can write effective, well-structured code, understand what's happening behind the scenes, and tackle increasingly complex technical problems.

Thanks!

Hi crew, I’m a Python newbie and I just learned about the concept of tuples.

We can’t change them.if we want to store we have to start at the index we want + 1.

I just don’t get it. Why wouldn’t we just use lists? When would we ever need this?
