多线程

import threading
import timedef sing():while True:print("sing a song")time.sleep(1)def dance():while True:print("chang tiao rap")time.sleep(1)if __name__ =='__main__':# 此时只能执行一个函数，必须等到该函数执行完才行# sing()# dance()# 改进 同时进行tread01=threading.Thread(target=sing)tread02=threading.Thread(target=dance)tread01.start()tread02.start()

import threading
import timedef sing(msg):while True:print("sing a song"+msg)time.sleep(1)def dance(msg):while True:print("chang tiao rap"+msg)time.sleep(1)if __name__ =='__main__':# sing()# dance()tread01=threading.Thread(target=sing,args=("googd",))# 把字典的值传进去tread02=threading.Thread(target=dance,kwargs={"msg":"good"})tread01.start()tread02.start()

使用Process完成多进程

import multiprocessing
import threading
import timedef sing():while True:print("sing a song")time.sleep(1)def dance(msg):while True:print("chang tiao rap"+msg)time.sleep(1)if __name__ =='__main__':# sing()# dance()# 不变tread01=multiprocessing.Process(target=sing)tread02=multiprocessing.Process(target=dance,kwargs={"msg":"good"})tread01.start()tread02.start()

import multiprocessing
import threading
import timedef sing():print("sing a song")yieldif __name__ =='__main__':g=sing()print(type(sing()))print(type(g))<class 'generator'>
<class 'generator'>
