Installing functools gives me AttributeError 'module' object has no attribute 'compose'

Python2.7 comes with the functools module included.

You can install functools32 if you want to get the lru-cache decorator, which was introduced with Python3.2.

Edit: I actually checked this. I got the same error when I tried to pip-install functools with Python2.7. Simply do import functools and proceed as usual.
