退出循环 python 3

Question

我是 python 的新手，我得到了这段代码，我希望它允许在输入时随时输入单词 "exit"。一旦完成，它就会关闭脚本。

任何帮助将不胜感激。

import sys

while True:

    def inputs():   
        first=input("Enter your first name: ")
        last=input("Enter your last name: ")
        gender=input("Enter your gender: ")
        form=input("Enter your form: ")

        file = open("signup.txt", "a")
        #Records the user's details in the file
        file.write("\nFirst name: "+first+", Last name: "+last+", Gender: "+gender+", Form: "+form)
        #Closes the file
        file.close()

        if input(inputs) == "exit":
            sys.exit()

    inputs()

Answer 1

你可以封装输入函数在"exit"字处退出:

import sys

def exitInput(prompt):
  pInput = input(prompt)
  return pInput if pInput != "exit" else sys.exit()

def inputs():
  first = exitInput("Enter your first name: ")
  last = exitInput("Enter your last name: ")
  gender = exitInput("Enter your gender: ")
  form = exitInput("Enter your form: ")
  file = open("signup.txt", "a")
  file.write("\nFirst name: "+first+", Last name: "+last+", Gender: "+gender+", Form: "+form)
  file.close()

inputs()

Answer 2

每次输入后都可以检查是否退出。如果是 exit 则终止程序。作为您的代码，您可以在每次输入后输入下面给出的代码

if input(inputs) == "exit":
        sys.exit()
