Question

Google App engine documentation states that it is possible to upload and use third party libraries provided they written in pure Python.

What are the steps I need to take to do this?

Answer 1

What I did is created a file called fix_path.py in my root directory that looks like this:

import os
import sys
import jinja2   
# path to lib direcotory
sys.path.insert(0, os.path.join(os.path.dirname(__file__), 'lib'))

Then I created a lib directory, and drop the module in there.

For example, I use WTForms. My file structure looks like this.

• lib
  • wtforms
• fix_path.py
• somefile.py

when I am ready to call it from my somefile script

import fix_path # has to be first.
import wtforms

here is this example in my github source. checkout fix_path.py for setup and views.py for usage.
