可以调用`multiprocessing.Process`类来创建一个进程。 ```python """ @Date 2021/4/5 """ import time import multiprocessing def demo1(): while True: print("--1--") time.sleep(1) def demo2(): while True: print("--2--") time.sleep(1) def main(): p1 = multiprocessing.Process(target=demo1) p2 = multiprocessing.Process(target=demo2) p1.start() p2.start() if __name__ == '__main__': main() ```
