python多线程

单线程， 按次序循环

#coding=utf-8
import time

def sayHi():
    print("Hello I am Se7eN_HOU")
    time.sleep(1)

if __name__ == "__main__":
    for i in range(5):
        sayHi()

多线程，睡眠时其他线程会上，相当于插队，也可以理解为谁先空闲谁先上，这是无序的执行

#coding=utf-8
import threading
import time

def sayHi():
    print("Hello I am Se7eN_HOU")
    time.sleep(1)

if __name__ == "__main__":
    for i in range(5):
        t = threading.Thread(target = sayHi)
        t.start()
