python多线程并发

测试多线程并发

1.首先定义线程函数

from threading import Thread

class Myprocess(Thread):
    def __init__(self):
        super(Myprocess,self).__init__()

    def run(self):

2.在main函数中进行多线程调用

if __name__=='__main__':
    process_list = []
    for i in range(4):
        p = Myprocess() #实例化进程对象
        p.start()
        process_list.append(p)
        print("->>>>>>>>>>>>>>>",i)
