Import result from another script in python

Question

I have a supporting library

##lib.py
def bagwords(X):
    XXX
    return data

Now in my abc.py I'd like to use lib.py and returned data

##abc.py
import lib
lib.bagwords(X)

I'm wondering in my abc.py, how can I pass variable to lib.py and use return data?

Aside from a second typo (`bagwords` vs `badwords`), it seems that you know how to do this. All the parts are in place. — Arya McCarthy, Apr 25 '17 at 06:04

##abc.py
import lib

data = lib.bagwords(X)

This above will throw an error because X is not defined, but at least it code demonstrates how to get data from the lib.bagwords() function.

OK - from the comment ("No, X is defined in abc.py, my problem is: it'll have error: module lib has no attribute bagwords, i don't know why.") is known that X is defined in abc.py, so there will be no error because of that

One possible reason for the error mentioned in the comment is if there is ANOTHER module named lib in the search path and it is found and loaded first. So how to avoid the error?

Rename lib.py to myLibrary.py and use the code:

##abc.py
import myLibrary

data = myLibrary.bagwords(X)

I have tested that it works, so it should work also for you :) . Happy coding!

are lib.py and abc.py in the same directory then create the following empty python file __ init __.py to allow import from this directory.

Change your abc.py file as follow:

##abc.py
from lib import bagwords
lib.bagwords(X)

PS: please have a look at Python: import module from another directory at the same level in project hierarchy

I tried this, but it said ImportError: cannot import name 'bagwords' – LookIntoEast Apr 25 '17 at 06:20
do you have created the __ init __.py file? If lib.py is in another path you have to use **from /lib import bagwords**. – mepi0011 Apr 25 '17 at 06:27
No! I think this is problem. But how should I create? Just empty file only with name? – LookIntoEast Apr 25 '17 at 06:30
In my test the library is loaded from current directory without any ____init____.py file. – Claudio Apr 25 '17 at 06:36
