Thanks to whoever in this sub suggested CS50 Harvard YouTube & Automate the boring stuff book!

I'm 2 weeks in and feel like I'm in "good" place so far!

I'm also using AI to create similar problem sets to CS50's so I can practice more to ensure full understanding of the lecture!

new to python, Im making a calculator but when i try to make the code be able to handle a word without crashing it just doesnt work, it just goes and ask for the operator without restarting the loop, tried ai to fix it and explain it to me but didnt do nothing.

num1 = None
num2 = None
result = None


while num1 == None or num2 == None:
    try:
        num1 = float(input("Enter first number: "))
    
    except ValueError:
        print("must enter a valid number")
        num1 = None
        continue


    try:
        num2 = float(input("enter second number"))


    except ValueError:
        print("must enter a valid number")
        num2 = None
        continue
    operator = input("Enter operation (+, -, *, /)")


    if operator == "+":
        result = (num1 + num2)


    elif operator == "-":
        result = (num1 - num2)


    elif operator == "*":
        result = (num1 * num2)


    elif operator == "/" and num2 == 0:
        result = ("cant divide by zero")


    elif operator == "/" and num2 != 0:
        result = (num1 / num2)


    else:
        result = ("Invalid operator")


    if result == float or int:
        print(result)
        num1 = None
        num2 = Nonenum1 = None
num2 = None
result = None


while num1 == None or num2 == None:
    try:
        num1 = float(input("Enter first number: "))
    
    except ValueError:
        print("must enter a valid number")
        num1 = None
        continue

i tried install python in vista and it mid freeze in the instalation and i even use the repair tool in the installer but i keeped having the error "The Procedure entry point GetActiveProcessor could not be located in the dinamic link library KERNEL32.dll" and then a Python has stoped working, something weird here is why is it calling kernel32.dll? and i do not expet support since this is a outdated version but in windows 7 starter (same pc) it worked fine, i dont know if this is else becuse im using an modified version of vista (Vienna) or is else something to do with 3.8.10 in vista

import requests


# Add ?format=j1 to get a proper JSON response
url = "https://wttr.in"
response = requests.get(url)
data = response.json()


# This structure matches the j1 JSON format returned by wttr.in
current_temp = data['current_condition'][0]['temp_C']
print(
f
"Current temperature: {current_temp}°C")

I keep getting this exact SAME error whenever I work with public API's. I save the new codes in the files.

Hey everyone!

I’m looking for a coding buddy who’s also taking 100 Days of Code: The Complete Python Pro Bootcamp by Dr. Angela Yu on Udemy.

I’m just starting with Day 1 and would love to connect with someone taking the same course so we can learn together throughout this 100-day journey.

The goal is to keep each other motivated and accountable, share our progress, discuss what we’ve learned, help each other when we get stuck, and celebrate our little wins along the way.

It would be great to have someone who’s also a beginner, but anyone taking the same course is welcome! No pressure to be an expert — we’re here to learn and improve together.

If you’re taking the same course, feel free to comment or send me a message. Let’s keep each other motivated and complete these 100 days together!

Happy coding!

In order to validate (using pytest) a python module which is not in my path or relative folders, I want to hack the import path.

I'm wondering what alternatives there are to doing a PYTHONPATH hack. I could use https://docs.pytest.org/en/7.1.x/reference/reference.html#confval-pythonpath, but that applies to the entire session as I understand it. And I only want to change one suite, so I am writing a quick fixture that will roughly look like (hard-coded for simplicity) @pytest.fixture(scope="function") def modules_path(): old_path = sys.path extra_path= os.path.abspath("c:/otherpath/other") # replace constant with a func sys.path.insert(0, extra_path) yield extra_path sys.path = old_path I've always felt there was a better way to do import path hacks that nobody had ever told me about. Or is this @fixture approach not as evil as I assumed it was, and was merely biased by painful memories whenever I did use it. Alternatives?

I want to learn python but all of the online tutorials just tell me how to make a certain game but i want to learn how it works so if anyone can help me with this please let me know

Hey everyone! I'm planning to learn Data Structures and Algorithms using Python.

Is it worth learning DSA with Python for placements, coding interviews, and future software engineering jobs? Or is it better to learn DSA using C++ or Java?

For those who have experience, which language would you recommend and why?

What are the best Windows laptops I can get for AI development, machine learning, and video editing? I’m looking for a laptop that can handle demanding tasks smoothly and is suitable for long-term use. Please recommend the best options based on performance, specifications, . I’d really appreciate your help!

It should include both code input and algorithm analysis.

Hey guys, i wanna learn Python from scratch. I dont have any prior knowledge about any coding language. Please tell me from where should i learn. Mainly for Computational modelling, SciPy,NumPy etc

For context: i started the pcep test while forgetting that it was still connected to a 2nd monitor and my cursor flew into the 2nd screen which got me flagged for cheating. What would be the best course of action right now for me?

I am a post-bacc student currently in a Python for Web API online course. We just wrapped up our calculator application unit, where we learned how to build comprehensive dynamic tests using OOP design patterns. However, I finished the unit a lot more lost than when I started. Building parameterized tests still puzzles me, especially whenever I'm building the majority of a test from scratch rather than fixing minor errors in the code. Even when I do use AI to help me work through my assignments, none of it really sticks. Most of the time, I feel like I'm copying and pasting code whenever mine is incorrect and not really learning.

What are resources that you all would recommend for learning how to build application tests and files with OOP concepts? Any online resources with interactive, hands-on lessons would be greatly appreciated.

Recently, I got back into Python, so I decided to review some concepts I had forgotten by solving one Project Euler problem per day.

However, when I got to Problem 3 (Largest Prime Factor), I decided to use a library to check whether a number is prime. Since I had uninstalled Python when I stopped studying it, I had to install Python 3.15.

When I first tried to install the library, the terminal said that it didn't recognize pip. I managed to get it working by using python -m pip, and the installation seemed to work. However, when I ran my code, Python still couldn't recognize the library.

The next day, while solving Problem 4 (Largest Palindrome Product), I decided to use NumPy and np.arange() instead of range(), but the same thing happened: the installation appeared to work, but when I ran my code, Python couldn't find the library.

I tried uninstalling and reinstalling Python, but the problem persisted.

In these particular cases, I could still solve the problems without those libraries, but eventually, I'll need packages like pandas, Tkinter, and others, so I'd like to figure out what's going wrong.

If anyone knows how to fix this, I'd really appreciate the help!

Thanks in advance!

I saw this link online on social media with a reminder to update dependencies but I don’t really understand it, how I am affected, and how I can address this.

A compromised key for a certificate authority can be used to issue certificates to enable MITM attacks.

I'm a first-year IT student based in Australia, learning how to make small Python tools useful to someone else, not just running on my own machine.

For a simple CSV-processing script on Windows, how would you handle packaging and dependencies for a non-technical user? An executable, a launcher, or something else?

Also curious what instructions and error messages you include so the person isn't stuck the first time a file is missing or formatted differently. I'm asking about the handover side rather than a specific code error.

It's one i've been thinking about for a while and i'd love to know all of your opinions about it! https://www.codewars.com/kata/6ad8699fccb2dbf6de41f760/python

now if this isn't the right place for dumb stupid stupid dumb tech favours shove me off to another r/

basically I was thinking "what if I could play tf2 with Wii remotes because tf2 has razer hydra support, so if you just translated the Wii remote inputs into razer ones then it would work in tf2"

I've already got a program called gunmote that can translate Wiimote inputs to mouse+keyboard so I thought you could just translate the m+k inputs to hydra inputs

btw the reason I'm not using steam input is because tf2 has this weird aiming for the hydra https://youtu.be/MYAjBFhzgIU that's suspiciously similar to the Wii era aim style

so um ye

Doing horribly in beginners Python and want to know how important it is or is Java better to start off with

Hace no mucho decidí por mi cuenta aprender python de manera autodidacta y con cursos al menos con certificación o con instituciones que son reconocidas para ir a la universidad ya preparado. -Cualquiera puede buscar un curso y puede buscar una institucion que de videos para aprender como es el caso del MIT o Harvard que dan cursos gratis o videos enseñando solamente que no muchos averiguan- y mi pregunta es. Sirven esos cursos? Alguna recomendación? Y por último pero no menos importante... Porque dicen mucha gente que la programación o algo que tenga que ver con tecnología es para gente introvertida o "Virgen"? Entiendo que tu trabajo no será estar con muchas personas o tan siquiera con personas y estarás en una computadora. Y te puedo decir yo que soy la persona más -al menos a mi pensar- expresiva o sociable que hay al menos en mi grupo de amigos. Eso y que pues no me parezco en nada a lo que plantean o dicen las personas. Me han dicho que hasta parezco que estudio/practico otra cosa que eso.
