Module import fails unless in current directory - Python3

Question

I have written a small Facebook OAUTH function that I want to use as a module whenever I need to generate a token to post to my FB feed or page. The problem is unless I'm in the directory that fb_auth is in I can't call the module.

Here's my code:

#!/usr/bin/env python3

''' Facebook authorization module'''

import requests
import os

def get_token(app_id, app_secret):
    payload = {'grant_type': 'client_credentials', 'client_id': app_id, 'client_secret': app_secret}
    response = requests.post('https://graph.facebook.com/oauth/access_token?', params=payload)
    result = eval(response.text)
    token = result['access_token']
    return token


if __name__ == '__main__':

    get_token()

So when i'm in the working directory (/home/scripts/python/fb_auth/)the module will import and function as it's supposed to:

>>> from fb_auth import get_token
>>> import os
>>> home = os.environ['HOME']
>>> work = home + '/scripts/python/'
>>> keys = work + 'apikeys'
>>> with open (keys, 'r') as f:
...    keys = eval(f.read())
... 
>>> app_id = keys['fb_keys']['riverwarn']['app_id']
>>> app_secret = keys['fb_keys']['riverwarn']['app_secret']
>>> get_token(app_id, app_secret)
'194XXXXXXXXXXXXXXXXXXXXXXXXXXXY_OM'

However, if I'm not in the working directory (/home/scripts/python/) I get nothing:

>>> import fb_auth
>>> fb_auth.get_token(app_id, app_secret)

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: module 'fb_auth' has no attribute 'get_token'

>>> from fb_auth import get_token

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: cannot import name 'get_token'

Do I need to put this in the main Python modules folder to make this work correctly?

It wouldn't find it because it doesn't appear in the sys.path. You can add it to the sys.path by installing it. See full documentation here: https://docs.python.org/2/install/#how-installation-works
