Python for循环

import time
from multiprocessing import Process


def f1():
    time.sleep(0.5)
    print(‘xxx‘)

if __name__ == ‘__main__‘:
    p_list = []
    #for循环创建子进程,并且完成主进程等待所有子进程执行结束,才继续执行
    for i in range(10):
        p = Process(target=f1,)
        p.start()
        p_list.append(p)
        p.join()
    # for pp in p_list:
    #     pp.join()

    print(‘主进程结束‘)
