loop 8
loop 9

2、for循环设定步长

3、for + If 限定次数判断Password

code

# Author:黑猴子

age_of_heihouzi = 18

for i in range(3):
    guess_age = int(input("guess age:") )
    if guess_age == age_of_heihouzi :
        print("yes, you got it. ")
        break
    elif guess_age > age_of_heihouzi:
        print("think smaller...")
    else:
        print("think bigger!")
else:
    print("you have tried too many times..fuck off")

运行
