How to NOT write python codes

I found a piece of art in a code today. So I'm sharing it to you.

The guy was trying to check if a variable 'member' is a class from the module 'mod'

He figured that str(member) would return it's class representation, something like that:

>>> str(member)
<class 'polygon.rectangle.square.SimpleSquare'>

He also figured that the object 'mod' had a 'name' attribute:

>>> mod.__file__
'polygon.rectangle.square'

So, to check if the object 'member' is a class from the module 'mod' he did:

>>> if str(member).find(mod.__name__) > 0:
... 

The correct way to do this:

If you want to check if a class is from a givem module, you can use the 'inspect' package:

>>> import inspect
>>> inspect.getmodule(member) is mod
True
