第一版，缺点只能猜一次。
age_of_archerzon = 22 guess_age = int(input("guess age:")) if guess_age == age_of_archerzon: print("yes,you got it!")
break elif guess_age > age_of_archerzon: print("think it smaller!") else: print("think it bigger!")
第二版，通过运用while循环实现了猜3次后退出。
优化版，将while循环改为for循环，
age_of_archerzon = 22 for i in range(3): guess_age = int(input("guess_age")) if guess_age == age_of_archerzon: print("yes,you got it!") break elif guess_age > age_of_archerzon: print("think it smaller!") else: print("think it bigger!")
