while 循环优化版本

#for 循环的else 是按顺序执行  break 不走
for i in range(3):
    guess_age = int(input("guess age："))
    if guess_age==age_of_oldboy:
        print("yes,you got it.")
        break
    elif guess_age > age_of_oldboy:
         print("think smaller...")
    else:
         print("think bigger!")
else:
    print("you have tried too many times.. fuck off") 

for循环

for i in range(0,10,2):
    print("loop",i)
程序优化 for 

while count<3:
    guess_age = int(input("guess age："))
    if guess_age==age_of_oldboy:
        print("yes,you got it.")
        break
    elif guess_age > age_of_oldboy:
         print("think smaller...")
    else:
         print("think bigger!")
    count+=1
    if count==3:
        continue_confirm=input("do you want to keep guessing..")
        if continue_confirm !='n':
            count=0
            print(continue_confirm)
# else:
#     print("you have tried too many times.. fuck off")
