最明白的循环

count = 0
while True:
    print("count:",count)
    count = count+1
    if count == 1000:
        break

 

#改成for循环，控制三次
#换成for语句：()里面 定义循环的次数

age_of_oldboy = 56

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!")
    # if count == 3:
    #     countine_confirm = input("do you want to keep guessing..?")
    #     if countine_confirm != 'n':
    #         count =0
else:
    print("you have tried too many times..fuck off")

#换成while循环。

age_of_oldboy = 56

count = 0
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
#如果三次都错了的话，就询问是否继续，如果输入n就退出。
    if count == 3:
        countine_confirm = input("do you want to keep guessing..?")
        if countine_confirm != 'n':
            count =0
#else:
#    print("you have tried too many times..fuck off")

 

 

#continue跳出本次循环，继续下一次循环

# for i in range(0,10):
#     if i <3:
#         print("loop ",i)
#     else :
#         continue
#     print("hehe...")
