python import results in nameerror

问题

This seems pretty basic, so I must be missing something obvious. Goal is to import a module from the same directory. I've broken it down about as simple as I can and I'm getting the nameerror.

file import_this.py:

def my_function(number) :
    print number + 2

file import_test.py:

import import_this
my_function(2)

Do I have to specify the directory the import file is in? (It's in the same as the test file). Also, can I test to see what modules are imported?

回答1:

You are accessing the function incorrectly.

Either use the following

import import_this
import_this.my_function(2)

or do,

from import_this import my_function
my_function(2) 

回答2:

Alternatively (apart from @mu's answer above),

>>>import import_this as it

.. and then,

>>> it.my_function(2)
