why is the error piwintypes in python

You probably mean ValueError instead of "piwintypes" error. The ValueError occurs when a function receives an argument of the correct type, but with an inappropriate value. To handle this error in Python, you can use a try-except block like this:

main.py
try:
    # Your code that may raise a ValueError
except ValueError as e:
    print("An error occurred:", e)
108 chars
5 lines

Make sure to replace the comment with the code that could potentially raise a ValueError.
