python的动态加载机制？？

if __name__ == '__main__':

    import sys
    from PyQt5.QtWidgets import QApplication
    app = QApplication(sys.argv)  

#####################################################   

    print('main')
    import sys
    sys.path.append("../")

    module_name = "view"   #模块名
    class_name = "HomeView" #类名
    method = "show"          #方法名
    module = __import__(module_name) # import module
    print ("#module:",module  )
    print('dir', dir(module))
    cl = getattr(module,class_name)
    print("#class:",cl  )

    obj = cl() # new class
    print("#obj:",obj  )
    mtd = getattr(obj,method)
    print("#method:",mtd  )
    mtd() # call def  

#####################################################
    sys.exit(app.exec_())

需要在__init__.py文件中引出才行....囧
