python中for循环

Posted 2020-10-30

1、打印0-9 十个数字

for i in range(10):
        print(i)

2、打印偶数：

for i in range(0,10,2):
        print(i)

3、if判断中猜游戏，升级(只能猜三次，超过三次没猜对，提示退出)

_age = 18

for i in range(3):
    guess_age = int(input("guess_age:"))
    if guess_age == _age:
        print("GoodLuck!")
        break
    elif guess_age > _age:
        print("cai da le ")
    else:
        print("cai xiao le ")
else:
    print("chao guo san ci qing tui chu!!!")
