Importing from directory gives ImportError

Question

I have the following directory structure, in Ubuntu:

/Test/Foo
/Test/Foo/foo.py

If I am in /Test , and I run python from the command line, followed by from Foo import foo , I get the following error: ImportError: No module named Foo .

But this is very confusing, since according to here , one of the directories used to search when importing is the directory from which the script was invoked. If I print out sys.path though, it does not include /Test , it just includes other standard Python directories.

Any idea what is going on?

Answer 1

If I'm getting you right, what you are trying to achieve here is the Foo to be a package and foo be a module.

Since Foo is not made into a package (You don't have __init__.py in the directory), it is not recognized as a package and thus not imported.

When you move into /Test/Foo , then you are simply importing the module foo , which will work.

What you possibly need to do here is to create an __init__.py file inside /Test/Foo and then import the module from the package.

Or you can try relative imports. Something like from .Foo import foo .

If you just need a function try this (python 2.7):
sys.path.insert() inserts the directory specified in the path python uses to find files.
commify.py is a file in subdirectory xyz that contains a function commify(value)

import os
import sys
sys.path.insert(0, os.getcwd() + r'\xyz')
from commify import commify

print commify(12345678)

output: 12,345,678
