python实现多进程和多线程

创建多进程方法：

import multiprocessing
import time
 
 
def sing():
    for i in range(3):
        print("i am sing ooo~")
        time.sleep(0.5)
 
def dance():
    for i in range(3):
        print("i am dance lll~")
        time.sleep(0.5)
 
if __name__ == '__main__':
    # 2.使用进程类创建进程对象
    # target ：指定进程执行的函数名，不加括号
    sing_process = multiprocessing.Process(target=sing)
    dance_process = multiprocessing.Process(target=dance)
 
    # 3. 使用进程对象启动进程执行指定任务
    sing_process.start()
    dance_process.start()

多线程创建

import threading
import time

def sing():
    for i in range(3):
        print("i am sing ooo~")
        time.sleep(0.5)
 
def dance():
    for i in range(3):
        print("i am dance lll~")
        time.sleep(0.5)

 
if __name__ == '__main__':
    sing_thread = threading.Thread(target=sing)
    dance_thread = threading.Thread(target=dance)
 
    sing_thread.start()
