代码如下：

def get_platform():
    import platform
    sys_platform = platform.platform().lower()
    if "windows" in sys_platform:
        print("Windows")
    elif "macos" in sys_platform:
        print("Mac os")
    elif "linux" in sys_platform:
        print("Linux")
    else:
        print("其他系统")


if __name__ == "__main__":
    get_platform()
