Python | os.urandom() method

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 :

# 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'
