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'
