python多进程案例

# 进程的创建步骤
import time
def sing():
    for i in range(3):
        print("唱歌")
        time.sleep(0.5)
def dance():
    for i in range(3):
        print("跳舞")
        time.sleep(0.5)
# 导入进程包
# 1.导入进程包
import multiprocessing
if __name__ == '__main__':
    # 2.通过进程类创建进程对象,有三个参数：target任务名；name进场名一般不设置；group进程组，目前只能使用None
    sing_process = multiprocessing.Process(target=sing)
    dance_process = multiprocessing.Process(target=dance)
    # 3.启动进程执行任务
    sing_process.start()
    dance_process.start()
