如果输入错误,我怎样才能再次询问相同的输入？

Question

players = input("How many players?")
if players == "1":
    p1 +=1
elif players == "2":
    p2 +=1
else:
    print("Invalid Input")
    players = input("How many players?")

当输入无效输入时,如何让else重复？

Answer 1

break输入时使用无限循环并输出:

while True:
    players = input("How many players?")
    if players == "1":
        p1 += 1
        break
    elif players == "2":
        p2 += 1
        break
    else:
        print("Sorry, please pick 1 or 2. Let's try again")
