1、循环十次退出while循环：

count = 0
while True:
    print("count:",count)
    count = count + 1  #count +=1
    if count ==10:
        break

2、猜年纪：

age_of_oldboy = 56

#guess_age = int(input("guess age:"))

count = 0
while count<3:
    guess_age = int(input("guess age:"))
    if guess_age == age_of_oldboy :
        print("yes, you got it. ")
        break   #跳出循环就不走else
    elif guess_age > age_of_oldboy:
        print("think smaller...")
    else:
        print("think bigger!")
    count+=1
else:
    print("you have tried too many times.. ")

3、达到3次，提示是否继续竞猜，输入n退出：

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
    if count == 3:
        countine_confirm = input("do you want to keep guessing..?")
        if countine_confirm != ‘n‘:
            count = 0
