python - 当我定义中断代码时，为什么我的 while 循环失败了？

Question

我是 Python 的新手，正在探索一个简单的副项目以了解函数和循环的工作原理。

我这里有这段代码

age = 0

def ageInMonths (age):
    months =  int(age) * 12
    return print('You are ' + str(months) + ' months old!')

def ageInDays(age):
     days = int(age)*365
     return print('You are ' + str(days) + ' days old!')

def ageInHrs(age):
    hrs = int(age)* 8765.81
    return print('You are ' + str(hrs) + ' hours old!')

    def ageinMin(age):
       minutes = int(age)* 525948.8
       return print('You are ' + str(minutes) + ' minutes old!')

    def ageinSec(age):
       sec= int(age)* 31556926
       return print('You are ' + str(sec) + ' seconds old!')


def agePrint(age):
    age=age
    ageInMonths(age)
    ageInDays(age)
    ageInHrs(age)
    ageinMin(age)
    ageinSec(age)
      print('Done')
    return 

while age != 99:

    print( 'Please enter your age?')

    age = input()
    if age == 99:
     break


    print('You are ' + age + ' years old!')


    agePrint(age)

每次我输入 99 时，while 循环都不会中断。关于我哪里出错的任何建议..

您忘记将输入转换为int:

age = int(input())

如果您没有明确地这样做，age 将是一个字符串，并且自然地 '99' != 99。
