3. Convert Bytes to String Using the Codecs Module Yet another method to convert bytes to string in Python is using thedecode()function from the built-incodecsmodule. This module provides convenience functions for encoding and decoding.
4. Using codecs.decode() function to convert bytes to string in Python In this example, we will be using codecs.decode() function.This function is used to decode the binary string into normal form.Let us look at the example for understanding the concept in detail. ...
