I am new to python. I am reading about the crypt() function for UNIX passwords. 

import crypt
crypt.crypt("egg","HX")

Here is what I get after running my program

File "...", line 2, in <module> crypt.crypt("egg","HX")
TypeError: 'module' object is not callable

I've read several posts on google and stackOverflow and found that I have to import the library so:

from crypt import *
crypt.crypt("egg","HX")

but now I am getting this error:

Traceback (most recent call last):
File "crypt.py", line 1, in <module>
from crypt import *
File "...", line 2, in <module>
crypt.crypt("egg","HX")
NameError: name 'crypt' is not defined

How can this error be resolved? And what is the difference between 

import smth

and 

from smth import smth1?

Thank you!

    The problem is that you named your program `crypt.py`. So when it does `import crypt` it imports _itself_. – PM 2Ring Mar 30 '17 at 10:48

    The question I linked talks about the `requests` module, but it's the _exact same thing_ that's happening for you with the `crypt` module: you gave your program the same name as the module you're trying to import, and Python finds your program first before it finds the other module with the same name. – PM 2Ring Mar 30 '17 at 10:55
