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' Paul
