多线程多进程用的方式
# Demo Describe:多线程写法
from threading import Thread # 线程
from multiprocessing import Process # 进程
# start--------1,多线程调用的方式一----------------------
def fun1():
for i in range(100):
print('fun()1,', i)
def fun2():
# 创建线程
t = Thread(target=fun1)
# 开启多线程状态,由CPU决定执行具体时间
t.start()
for i in range(100, 200):
print('fun()2,', i)
# fun2()
# end--------1,多线程调用的方式一----------------------
# start--------2,多线程调用的方式二----------------------
class MyThread(Thread):
def run(self):
for i in range(100):
print('子线程运行,', i)
# if __name__ == '__main__':
# t = MyThread()
# t.start()
# for i in range(100):
# print('main,',i)
# end--------2,多线程调用的方式二----------------------
# start--------3,多进程调用的方式一----------------------
