Can't Import Python Module From A Subdirectory With A Simple Import Statement

So I want to import a module from a python package that is a subdirectory of the one where the main script is located. This is the directory structure: maindir \ - main.py - mo

Solution 1:

It does import the module, it just doesn't make its name directly accessible. When you do import foo.bar, the name that is imported is foo, and bar is only accessible as an attribute of that. You use that form of import if that is what you want; that's what it's for. If you don't want that, use a different form of the import statement.

If you want to be able to type module instead of modules.module, either do import modules.module as module, as you found, or do from modules import module.

Solution 2:

When you import you still need to use the full package syntax to use the function foo.

The below should work

import modules.module
modules.module.foo() 

A better way to do this is

from modules importmodulemodule.foo()

A third less elegant way (but exactly the same as the above) is:

import modules.module as modulemodule.foo()
