I've tried without while loop in get_guess() function and it worked fine. I just don't see the point that we put while loop in side this function.
def get_guess(bad_guesses, good_guesses):
while True:
# take guess
guess = input("Guess a letter: ").lower()
if len(guess) != 1:
print("You can only guess a single letter!")
elif guess in bad_guesses or guess in good_guesses:
print("You've already guess that letter!")
elif not guess.isalpha():
print("You can only guess letters!")
else:
return guess

loop is to keep printing why an input was not accepted then re-ask for an input. Without the while
loop, an unaccepted input would print the message then return None
from the function call.
Post back if you have more questions. Good Luck!!
