random.getrandbits() in Python (original) (raw)

Last Updated : 14 Jun, 2022

random module is used to generate random numbers in Python. Not actually random, rather this is used to generate pseudo-random numbers. That implies that these randomly generated numbers can be determined.

random.getrandbits()

The getrandbits() method of the random module is used to return an integer with a specified number of bits. The number of bits required in the result is passed as an parameter in the method. Examples :

Input : getrandbits(4) Output : 14 (the binary equivalent of 14 is 1110 which has 4 bits)

Input : getrandbits(16) Output : 60431 (the binary equivalent of 60431 is 1110110000001111 which has 16 bits)

Example 1:

Python3 `

import the random module

import random

a random number with 4 bits

print(random.getrandbits(4))

a random number with 16 bits

print(random.getrandbits(16))

`

Output :

10 49195

Example 2:

Python3 `

import the random module

import random

5 random number with 4 bits

for i in range(4): print(random.getrandbits(4))

`

Output:

10 0 1 14
