可以同时运行两个无限循环吗? [英] Can two infinite loops be ran at once?

问题描述

我希望能够同时运行两个 True 循环.这可能吗?

I want to be able to have two while Trueloops running at the same time. Would this be possible?

我是Python的新手，所以我不知道如何解决这个问题.

I am extremely new to Python, so I do not know how to get round this problem.

这是我编写的代码:

import time

def infiniteLoop():
    while True:
        print('Loop 1')
        time.sleep(1)

infiniteLoop()

while True:
    print('Loop 2')
    time.sleep(1)

现在，它只打印循环1"

Right now, it just prints a 'Loop 1'

预先感谢

推荐答案

要一次运行两个循环，您要么需要使用两个线程，要么将循环交织在一起.

To run both loops at once, you either need to use two threads or interleave the loops together.

方法1:

import time
def infiniteloop():
    while True:
        print('Loop 1')
        time.sleep(1)
        print('Loop 2')
        time.sleep(1)

infiniteloop()

方法2:

import threading
import time

def infiniteloop1():
    while True:
        print('Loop 1')
        time.sleep(1)

def infiniteloop2():
    while True:
        print('Loop 2')
        time.sleep(1)

thread1 = threading.Thread(target=infiniteloop1)
thread1.start()

thread2 = threading.Thread(target=infiniteloop2)
thread2.start()
