if 'Q1 = yes':

if Q1 == 'yes':

import random

Q1 = input(
    """would you like to put your own words instead 
of heads or tails if so say yes if not say no, 
if you said no i will exit the code?"""
)

if Q1 == "yes": # you need to check equality with `==` between values/variable containing value
    Q2 = input( # Indentation should be consistent across the file as python is sensitive to indent
        """what word(s) or numbers(s) would 
    you like to use in your random 
    word or number picker?(also no 
    spaces in between numbers.)"""
    )
    y = random.choice(list(Q2))
    print(y)
elif Q1 == "no":
    print("bye")
