Python module import not working

Question

I am getting an error with the following code:

from os import getcwd
os.getcwd()

Traceback (most recent call last):
File "<pyshell#2>", line 1, in <module>
os.getcwd()
NameError: name 'os' is not defined

Anyone know why importing this way is not working?

Answer 1

There are two possibilities. The first one is to import the module and name the module every time calling the function:

import os
print os.getcwd()

Or you can import the method of the module directly and don't have to name the module when calling it:

from os import getcwd
print getcwd()

Answer 2

from os import getcwd
print getcwd()

When you have only imported getcwd and not os how can this work os.getcwd
