进程和线程的开启效率

code

from threading import Thread
from multiprocessing import Process
import os
 
 
def work(name):
    print('{} say hello'.format(name))
 
 
if __name__ == '__main__':
    # 在主进程下开启线程
    t=Thread(target=work,args=("thread",))
    t.start()
    print('主线程/主进程')
 
 
    # 在主进程下开启子进程
    t=Process(target=work,args=("progress",))
    t.start()
    print('主线程/主进程')
 

Outputs

macname@MacdeMacBook-Pro py % python3 cccccc.py
thread say hello
主线程/主进程
主线程/主进程
progress say hello
macname@MacdeMacBook-Pro py %
