如何编写循环以重复代码? [英] How do I write a loop to repeat the code?

问题描述

我是Python的初学者，我想重复这段代码.但是我真的不知道如何在没有"goto"的情况下做到这一点.我试图学习循环，但不了解如何应用循环.

I am a very beginner in Python and I want to repeat this code. But I don't really know how to do this without "goto". I tried to learn about loops but did not understand how to apply them.

import requests
addr = input()
vendor = requests.get('http://api.macvendors.com/' + addr).text
print(addr, vendor)

推荐答案

创建一个函数 repeat 并在其中添加代码.然后使用 while True 进行无限调用，或者使用 for range(6)中的i进行6次调用`:

Create a function repeat and add your code in it. Then use while True for infinite call or for i in range(6) for 6 times call`:

import requests
def repeat():
  addr = input()
  vendor = requests.get('http://api.macvendors.com/' + addr).text
  print(addr, vendor)
while True:
  repeat()

请注意，不建议以任何语言使用goto，并且在python中不可用.这会引起很多问题.

Note that goto is not recommended in any language and is not available in python. It causes a lot of problems.
