一个插件化的简单示例。缺点：动态加载导致没有代码提示

device.py

class Device(Serial, Transport):
    INSTALL_RESULT_PATTERN = r"(Success|Failure|Error)\s?(.*)"
    UNINSTALL_RESULT_PATTERN = r"(Success|Failure.*|.*Unknown package:.*)"

    def __new__(cls, *args, **kwargs):
        # s = importlib.import_module('.__init__', ['plugins'])
        p = Path(__file__).parent.joinpath('plugins/dumpsys.py')

        # s = importlib.util.spec_from_file_location('plugins', submodule_search_locations=[p])
        s = importlib.util.find_spec('.dumpsys', 'src.tmd.common.adb.plugins')
        m = s.loader.load_module(s.name)
        # m = importlib.util.module_from_spec(s)

        print(repr(m))
        print(type(m))
        print(dir(m))
        print(m.__all__)
        c = getattr(m, m.__all__[0])
        print(c)
        cls.__bases__ += (c,)
        print(cls.__bases__)
        return object.__new__(cls)
