Code example of randbytes() in Python

Code explanation

  • Line 1: We import the random module.
  • Line 3: We define the number of bytes that are generated i.e no_of_bytes.
  • Line 5: We generate random bytes using the method randbytes passing the value for n as no_of_bytes.
  • Line 7: We print the generated random bytes.
