线程的使用

# 1. 导入threading模块
import threading
import time


# 跳舞任务函数
def dance():
    for i in range(4):
        print("跳舞中...")
        time.sleep(0.2)


# 唱歌任务函数
def sing():
    for i in range(3):
        print("唱歌中...")
        time.sleep(0.2)

if __name__ == '__main__':

    # 2. 创建子线程对象
    # group: 表示线程组，目前只能使用None
    # target: 表示执行的任务名(函数名或者方发名),不能加小括号
    dance_thread = threading.Thread(target=dance)
    print(dance_thread, dance_thread.name)

    sing_thread = threading.Thread(target=sing, name="sing_thread2")
    print(sing_thread, sing_thread.name)

    # 3. 启动线程执行对应的任务
    dance_thread.start()
    sing_thread.start()

执行结果:

<Thread(Thread-1, initial)> Thread-1
<Thread(sing_thread2, initial)> sing_thread2
