I know that there are plenty of similar questions on stack overflow. But the common answer doesn't seem to be working for me.
I have a file structure like this
proj/
lib/
__init__.py
aa.py
bb.py
test/
__init__.py
aa_test.py
I figured that if I include the code in my test.py
import lib.aa
or
from lib import aa
I would be able to reference the modules in the lib/
directory. But that did not work.
So I tried to add to path, and it adds it correctly:
os.environ["PATH"] += ":%s" % os.path.abspath(os.path.join("..",""))
print os.environ["PATH"]
but even now when I try the import statements above... I keep getting the error
ImportError: No module named aa
or
ImportError: Importing from non-package <Something...>
Is there something obvious I am missing?
Is there a way to check if I have configured my __init__.py
files correctly, or to see my package hierarchy?
You need to update your sys.path
, which is where python looks for modules, as opposed to your system's path in the current environment, which is what os.environ["PATH"]
is referring to.
Example:
import os, sys
sys.path.insert(0, os.path.abspath(".."))
import aa
After doing this, you can use your functions in aa
like this: aa.myfunc()
There's some more information in the accepted answer for python: import a module from a directory
