Hi all,
I am working on Exercise 46 of Learn Python the Hard Way, and I’m stuck on running nosetests.
The error I get is an AttributeError where it says the module ‘collections’ has no attribute ‘Callable’. Pasting below for your reference.

I’ve been stuck here for a while now, so appreciate any help and guidance on this.
