Python Random Module

While writing code in Python, there is a need sometimes for developers to generate random numbers. Random numbers are very useful in building gambling games to deal a random hand to players, in cryptography and statistical sampling in Python code.

Python provides a very easy way to generate these random numbers by using the random module. These random numbers are very deterministic as they are generated using a seed value. Hence, they are not ideal for use in encryption. For a given seed, they always generate the same random numbers.

# import random module
>>> import random
# define the seed value to be used for generating random numbers
>>> random.seed(3)
# random numbers are always a value between 0 and 1
>>> print(random.random())
0.23796462709189137
>>> print(random.random())
0.5442292252959519
>>> print(random.random())
