python 多线程

import multiprocessing
import time,threading

def threading_run():
    print(threading.get_ident())#获取线程ID

def run(name):
    time.sleep(2)
    print('hello', name)
    t = threading.Thread(target=threading_run,)#每个进程下创建一个线程
    t.start()

if __name__ == '__main__':
    for i in range(10):#10个线程
        p = multiprocessing.Process(target=run, args=('bob%s'%i,))
        p.start()
    # p.join()

获取进程ID：

from multiprocessing import Process
import os


def info(title):
    print(title)
    print('module name:', __name__)
    print('parent process:', os.getppid())#获取父进程ID
    print('process id:', os.getpid())#获取自己进程ID
    print("

")


def f(name):
    info('33[31;1mcalled from child process function f33[0m')
    print('hello', name)


if __name__ == '__main__':
    info('33[32;1mmain process line33[0m')
    p = Process(target=f, args=('bob',))
    p.start()
    # p.join()
