我在尝试计算退休年龄的脚本中有错误

Question

我正在尝试计算一个人的年龄，以验证他是否已达到退休年龄。这是python 2.7from datetime import datetimedef getName():  name = input("What is your name?: ")  return namedef getAge():  age = input("How old are you?: ")  return int(age)def ifOrNot():  retirementAge = 65  if(getAge() >= retirementAge):    print("Hello  ",getName(), ", are you in retirment age")  else:    timeToRetirement = retirementAge - getAge()    print("Hello ", getName(), " are you not in retirement age, you need to wait ", timeToRetirement, " more").def main():  ifOrNot()main()“你多大了”这个问题在屏幕上出现了两次。然后显示一次“你叫什么名字”这个问题。然后是这些错误：Traceback (most recent call last):   File "main.py", line 22, in<module>    main()   File "main.py", line 20, in main    ifOrNot()   File "main.py", line 17, in ifOrNot    print("Hola ", getName(), " aun no estas en edad de retiro, te faltan ", timeToRetirement)   File "main.py", line 4, in getName    name = input("What is your name?: ")   File "<string>", line 1, in <module> NameError: name 'Diesan' is not defined我想先问名字，再问年龄，然后计算出能够退休的剩余年限。奇怪的是，我不需要使用datetime，对吧？

Answer 1

def getName():

  name = input("What is your name?: ")

  return name

input()在 python2.7 中尝试评估它作为函数获得的任何内容-raw_input()改为使用获取字符串，该字符串将作为纯字符串返回。

def ifOrNot():

  retirementAge = 65

  if(getAge() >= retirementAge):

    print("Hello  ",getName(), ", are you in retirment age")

  else:

    timeToRetirement = retirementAge - getAge()

    print("Hello ", getName(), " are you not in retirement age, you need to wait ", timeToRetirement, " more").

如果您未到退休年龄，getAge()将在第一个if语句中调用一次，然后在else语句中再次调用。考虑将结果分配给getAge()变量并重用它。此外，您在第二个语句.的末尾有一个迷路。print()

你是对的，你不需要使用datetime.

正确的代码如下：

def getName():

  name = raw_input("What is your name?: ")

  return name

def getAge():

  age = input("How old are you?: ")

  return int(age)

def ifOrNot():

  retirementAge = 65

  myAge = getAge()

  if(myAge >= retirementAge):

    print("Hello  ",getName(), ", are you in retirment age")

  else:

    timeToRetirement = retirementAge - myAge

    print("Hello ", getName(), " are you not in retirement age, you need to wait ", timeToRetirement, " more")

def main():

  ifOrNot()

main()

Answer 2

将答案保存在变量中：

def ifOrNot():

    retirementAge = 65

    name = getName()

    age = getAge()

    if (age >= retirementAge):

        print("Hello  ", name, ", are you in retirment age")

    else:

        timeToRetirement = retirementAge - age

        print("Hello ", getName(), " are you not in retirement age, you need to wait ", timeToRetirement, " more").
