Can't find getcwd() function definition in os.py file
Question: I thought that I should be able to see the source code of packages that I
import in Python from the Python Standard Library. When I opened the os.py
file, I didn't see any definition of getcwd(). Why is this so?


Answer: `os` imports system dependent functions with

    
    
    from posix import *
    

or

    
    
    from nt import *
    

where `getcwd` is defined as C function.
