Need help with defining messages and player guesses in a lottery

[Kanashi]

Hello, I'm experimenting with the definition function and have stumbled upon a problem which I do not know how to make it work.
I'm making a very simple lottery, the lottery_draws code works perfectly, however I'm trying to gain a better understanding of how the def functions work aswell as creating a guess system, depending on how many guesses you got right out of 5, it will print

I'm struggling with how to code the "Player guesses"
And when I print "message" nothing appears (I wrote this when message1 and message" only contained "text here" (so it didn't have "text here" + lottery_draws)

import random

### Lottery Draws List ###
lottery_draws = []

### Actual Random Lottery Draws ###
for i in range(0, 5):
    number = random.randint(1, 20)
    while number in lottery_draws:
        number = random.randint(1, 20)
    lottery_draws.append(number)

### Player Guesses ###

print('Take a 5 guesses, between 1-20')
guesses = input('')
    if guesses in lottery_draws:
        return("Congratulations, you got X guesses right")
    elif guesses in lottery_draws: # Is equal to "1"
        return("Congratulations, you got 1 guess right")
    else:
        return("Too bad, you didn't get a single guess right")

### The Finale ###
def message():
    message1 = "Today's lottery draws are: " + lottery_draws
    message2 = # "\nYou got X guesses right."
    return(message1 + message2)
