if (random.rand() < 0.5) { print('true') } else { print('false') }

The function add takes two arguments a and b and returns the sum of a and b.

## Print Statements

  All print statements have been removed from the code.
  Instead, a new function has been added called print_dict. 
  This function takes in a dictionary as a parameter and nicely prints the contents.
  When the code is run, it will create a dictionary of the variables and print it out.
  All print statements have been replaced with a call to print_dict.

## Random Number Generation

  All random numbers generated must come from a seeded source.
  The seed is passed in as a parameter to the neural network.
  In order to create a random number, we do the following:

    def generate_random_num(seed):
      return hash(seed) % 10000

  This code will generate a random number between 0 and 10000.
  We then call this function whenever we need to generate a random number.

## Sigmoid Function

  The sigmoid function has been changed to the following:

    def sigmoid(x):
      return 1.0 / (1.0 + pow
