Python | os.urandom() method

Last Updated : 18 Oct, 2019

OS module in Python provides functions for interacting with the operating system. OS comes under Python’s standard utility modules. This module provides a portable way of using operating system dependent functionality. os.urandom() method is used to generate a string of size random bytes suitable for cryptographic use or we can say this method generates a string containing random characters.

Syntax: os.urandom(size) Parameter: size: It is the size of string random bytes Return Value: This method returns a string which represents random bytes suitable for cryptographic use.

Example #1 :

Python3

# Python program to explain os.urandom() method 
        
# importing os module 
import os 
    
# Declaring size
size = 5

# Using os.urandom() method
result = os.urandom(size) 
    
# Print the random bytes string
# Output will be different everytime
print(result)

Output:

b'\xe2\xaf\xbc:\xdd'
