Here's something that might be wrong in Python (tried on v2.7):
class int(str): pass int(3) '3'
It's not wrong as such. It is allowed to define your own class that subclasses a builtin class, and it's allowed to shadow builtin names. So while this is (obviously) bad practice, it's not wrong.
For a simpler example:
Python 3.4.3 (v3.4.3:9b73f1c3e601, Feb 24 2015, 22:44:40) [MSC v.1600 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license" for more information.
str <class 'str'> str = "Hello" str 'Hello'
