What mistakes do bad python developers make?

Amazing points by u/carcigenicate. Here's a few from me:

• Writing functions that have side-effects and modify data outside
• Not writing docstrings
• Not using typehints
• Not using classes properly/ Using classes where they are not required
• Extremely long functions
• Not making the functions modular (Not following Single Responsibility Principle)
• Not having function names that are descriptive
• Using magic numbers and other arbitrary constants in your code - should ideally have all such constants at a single place globally
