Extra Info printed with Cryptographic Hashing code in Python

Question

So a while back I was working on a Cryptographic Hashing project for a class I am no longer in. The code works almost perfect but Prints out the letter "b" and then the given imput before t printing the hashes.

Example if imput is "I like pizza." Then the output wpuld be " b'I like pizza.'" then the hashes. Here is the code I figured a second set of eyes could give me an Idea of where I messed up. Its a mix of the code my professor provided and my own but it was about a year ago so I don't remember what is his and what is mine. He primarilly provided the hash list and the the code to import it from what I remember.

This is the code listed below:

import hashlib
import random

def main(s):
    hash_list = [ 
                    hashlib.md5(), 
                    hashlib.sha1(), 
                    hashlib.sha224(), 
                    hashlib.sha256(), 
                    hashlib.blake2b()
                ]
    hashing_name = ["md5", "sha1", "sha224", "sha256", "blake2b"]
    
    length_of_salt = 13
    salt = "".join(random.choice('0123456789') for i in range(length_of_salt))
    hexa = hex(int(salt))
    salt = hexa.split('x')[-1]
    salt = hexa.encode('utf-8')
    
    for i in range(5):
        m = hash_list[i]
        m.update(s+salt)
        print("Testing hash algorithm", hashing_name[i], "Hashed Password = ", m.hexdigest()+":"+hexa)
    
if __name__ == "__main__":
    s = input().encode('utf-8')
    print(s)
    main(s)

I was trying to get hashes, which I got, but it prints out extran information first.
