python - 新手在 Python 中遇到简单的 "while"重复

Question

程序的重点是询问用户的姓名(首字母自动大写)。

然后它会询问年龄和性别。如果 age 超过 130 或为负数，则会抛出错误

程序应该打印出所有信息，但我无法弄清楚 while 循环条件。谁能帮我弄清楚 while 循环条件？

-edit- 虽然 Pastebin 的链接被删除了，但我认为那里有重要的信息。所以，我仍然会给你链接: http://pastebin.com/UBbXDGSt

name = input("What's your name? ").capitalize()
age = int(input("How old are you "))
gender = input("From what gender are you? ").capitalize()

while #I guess I should write something behind the "while" function. But what?
    if age >= 130:
        print("It's impossible that you're that old. Please try again!")
    elif age <= 0:
        print('''It should be logical that ages are written in positive numbers! Well, try again! =)''')

age = int(input("How old are you? "))   

print("Your name is ",name, ". You are ", age, "years old." "\nYou are ", gender, ".")

Answer 1

如果有有效输入，您可以设置一个关闭/打开的标志。这将解决您的 while 循环

的问题

 name = input("What's your name? ").capitalize()
 gender = input("From what gender are you? ").capitalize()
 ok = False #flag
 while not ok:
    age = int(input("How old are you "))
    if age >= 130:
       print("It's impossible that you're that old. Please try again!")
    elif age <= 0:
       print('''It should be logical that ages are written in positive numbers! Well, try again! =)''')
    else:
       ok = True
 print("Your name is ",name, ". You are ", age, "years old." "\nYou are ", gender, ".")
