创建函数/类的线程

# 创建类的线程
import threading
import time


class MyThread(threading.Thread):
    def run(self):
        for i in range(3):
            time.sleep(1)
            msg = "我是[线程]" + self.name + '@' + str(i)
            print(msg)


if __name__ == "__main__":
    t = MyThread()
    t.start()  # run会被自动调用，可在run中调用其他自定义类方法

# 创建函数的线程
import  threading
import time


def func1():
    for i in range(5):
        time.sleep(1)
        print("func1---%d" % i)


def func2():
    for i in range(10):
        time.sleep(1)
        print("func2---%d" % i)


def main():
    t1 = threading.Thread(target=func1)
    t2 = threading.Thread(target=func2)
    
    while True:
        # 查看当前有多少线程
        print(threading.enumerate())
        time.sleep(1)


if __name__ == "__main__":
    main()
