Python : Cannot find any functions within my own module?

Question

I have created my own module with filename mymodule.py. The file contains:

def testmod():
       print "test module success"

I have placed this file within /Library/Python/2.7/site-packages/mymodule/mymodule.py

I have also added a __init__.py file, these have compiled to generate

__init__.pyc and mymodule.pyc

Then in the python console I import it

import mymodule

which works fine

when I try to use mymodule.testmod() I get the following error:

AttributeError: 'module' object has no attribute 'testmod'

So yeah it seems like it has no functions?

Answer 1

You have a package mymodule, containing a module mymodule. The function is part of the module, not the package.

Import the module:

import mymodule.mymodule

and reference the function on that:

mymodule.mymodule.testmod()

You can use from ... import and import ... as to influence what gets imported exactly:

from mymodule import mymodule

mymodule.testmod()

or

from mymodule import mymodule as nestedmodule

nestedmodule.testmod

or

from mymodule.mymodule import testmod

testmod()

etc.
