I keep getting an infinite loop. Some help or hint would be greatly appreciated. Its a mad lib with loops. The loop has to stop when user inputs 'quit 0'. user_str = input()

stop = "quit 0"

while True:

s = user_str. split()[0]

n = int(user_str. split()[1])

if stop == "quit 0 ":

break

print(" Eating " + str(n) + " " + s + " a day keeps the doctor away.")

user_str = input()
