Python | os.urandom() method Last Updated : 18 Oct, 2019 Comments Improve Suggest changes Like Article Like Report 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' Comment More infoAdvertise with us Next Article Python | os.urandom() method R Rajnis09 Follow Improve Article Tags : Python python-os-module Practice Tags : python Similar Reads Python | os.read() method OS module in Python provides functions for interacting with the operating system.
