zip transforms multiple lists into a single list of tuples of corresponding elements:

The Central Limit Theorem One reason the normal distribution is so useful is the central limit theorem, which says (in essence) that a random variable defined as the average of a large number of independent and identically distributed random variables is itself approximately normally distributed. In particular, if

Instead, you should use Python’s csv module (or the pandas library).

In order to train a neural network, we’ll need to use calculus, and in order to use calculus, we need smooth functions.
