I am working on your online book and projects using Python 3.5. Since I used a different and newer python version, I came across several problems and solved them by making some changes in network.py and mnist_loader files. Now the code is compatible with Python 3.5
The biggest problem is zip variables haven't len() attribute in 3.5. So I converted training_data, test_data to the list variables. I had to make a deep copy of original training and test data because when they are converted to list variables, they can't be reused.
