Random numbers of computers are generated by pseudo random numbers, which are produced by the small m polynomial sequence, in which each small sequence has an initial value, i.e. random seed. (Note: The cycle of a small m polynomial sequence is 6

Real random numbers are generated using physical phenomena such as throwing coins, dice, wheels, noise using electronic components, nuclear fission, and so on. Such a random number generator is called the physical random number generator, although
Random module and pythonrandom Module
The random module in Python is used to generate random numbers. Common functions are used as follows:
Random. randint
Function prototype: random. randint (a, B), which generates a randomIntegerN, where a
