No input with a function

Thanks for quick replies, I really appreciate it. Here is the full code:

BaseHealth = 100
BasePower = 100
BaseLuck = 100
def stats():

    print("Health: " + str(BaseHealth), "Luck: " + str(BaseLuck), "Power: " + str(BasePower))
valid = {'1', '2', '3'}
advantage = ""
while True:
    advantage = input('Do you pick extra health [1], extra luck [2], or extra power [3]: ')
    if advantage not in valid:
        print('Try again...')
    else:
        print("Your stats have been updated. They are as follows:")
        break

if advantage == 1:
    BaseHealth = 150
    stats()

elif advantage == 2:
    BaseLuck = 150
    stats()

elif advantage == 3:
    BasePower = 150
    stats()

Thanks in advance!
