Python编程：获取一个类对象的属性和方法

python3.6 下测试

# -*- coding: utf-8 -*-

class Demo(object): name = "demo" def instance_func(self): pass @classmethod def class_func(cls): pass @staticmethod def static_func(): pass


def print_attrs_by_dict(): """打印出属性""" print(Demo.__dict__.keys()) # dict_keys(['__module__', 'name', 'instance_func', # 'class_func', 'static_func', '__dict__', '__weakref__', # '__doc__'])


def print_attrs_by_dir(): """ 过滤所有属性 """ print(dir(Demo)) # ['__class__', '__delattr__', '__dict__', '__dir__', '__doc__', # '__eq__', '__format__', '__ge__', '__getattribute__','__gt__', # '__hash__', '__init__', '__init_subclass__', '__le__', '__lt__', # '__module__', '__ne__', '__new__','__reduce__', '__reduce_ex__', # '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', # '__weakref__', 'class_func', 'instance_func', 'name', 'static_func']


def filter_attrs_by_inspect(): """ 过滤出函数 少了类方法：class_func """ import inspect print([i for i in dir(Demo) if inspect.isfunction(getattr(Demo, i))]) # ['instance_func', 'static_func']


def filter_attrs_by_callable(): """过滤出可调用的函数 """ print([i for i in dir(Demo) if callable(getattr(Demo, i))]) # ['__class__', '__delattr__', '__dir__', '__eq__', '__format__', # '__ge__', '__getattribute__', '__gt__', '__hash__','__init__', # '__init_subclass__', '__le__', '__lt__', '__ne__', '__new__', # '__reduce__', '__reduce_ex__','__repr__', '__setattr__', # '__sizeof__', '__str__', '__subclasshook__', 'class_func', # 'instance_func', 'static_func']


if __name__ == '__main__': print_attrs_by_dict() print_attrs_by_dir() filter_attrs_by_inspect() filter_attrs_by_callable()
