python多线程实现多任务_python多线程实现多任务 mul

1.简单的线程

同时运行下面的sing和dance函数

import time
import threading
 
def sing():
    for i in range(2):
        print("唱歌...")
        time.sleep(1)
 
 
def dance():
    for i in range(2):
        print("跳舞...")
        time.sleep(1)
 
if __name__ == '__main__':
    sing_process = threading.Thread(target=sing)
    dance_process = threading.Thread(target=dance)
 
    sing_process.start()
    dance_process.start()

结果如下：

二 、带有参数的线程

import time
import threading
 
def sing(num):
    for i in range(num):
        print("唱歌...")
        time.sleep(1)
 
 
def dance(num):
    for i in range(num):
        print("跳舞...")
        time.sleep(1)
 
if __name__ == '__main__':
    sing_process = threading.Thread(target=sing,args=(2,))
    dance_process = threading.Thread(target=dance,kwargs={"num":2})
 
    sing_process.start()
    dance_process.start()

一样的结果
