100 common mistakes in Python - Hackers - Feb 3, 2025
I found this site which seems to be a good resource for people just starting to learn Python. However, there might be some reminders for advanced coders too! Take a look
100 common Python mistakes:

Example:
Code
Confusing append and extend
❌ Do not confuse append with extend. The following code fails because extend is intended for use with lists.
x = [1, 2, 3]
x.extend(4)
print(x) # TypeError
✅ If you want to add a single element, use append.
x = [1, 2, 3]
x.append(4)
print(x) # [1, 2, 3, 4]
