Just a bit confused

this:

1 = int(input("Savanah")
2 = int(input("ThinMints")
3 = int(input("Tagalongs")

is taboo.
You are essentially trying to override the numbers 1, 2 and 3
do this like:

choice = 0
while choice not in [1, 2, 3]:
    print('Please choose one of:')
    print("    1. Savanah")
    print("    2. ThinMints")
    print("    3. Tagalongs")
    choice = int(input())
print('You have chosen option: {}',format(choice))
