Forked to help me with follow http://neuralnetworksanddeeplearning.com/
There are no improvements made to the code. Rather, just reformatting and type hinting to help me follow the code easier.
These scrips are updated ones from the neuralnetworksanddeeplearning.com gitHub repository in order to work with Python 3.5.2
The testing file (test.py) contains all three networks (network.py, network2.py, network3.py) from the book and it is the starting point to run (i.e. train and evaluate) them.
In test.py there are examples of networks configurations with proper comments. I did that to relate with particular chapters from the book.
