我相信你想要的是这样的:

一个对象的属性列表

内置函数dir()可以完成这项工作。

摘自Python shell的help(dir)输出:

dir(...) dir([object]) -> list of strings If called without an argument, return the names in the current scope. Else, return an alphabetized list of names comprising (some of) the attributes of the given object, and of attributes reachable from it. If the object supplies a method named __dir__, it will be used; otherwise the default dir() logic is used and returns: for a module object: the module's attributes. for a class object: its attributes, and recursively the attributes of its bases. for any other object: its attributes, its class's attributes, and recursively the attributes of its class's base classes.

例如:

$ python
Python 2.7.6 (default, Jun 22 2015, 17:58:13)
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.

>>> a = "I am a string"
>>>
>>> type(a)
<class 'str'>
>>>
>>> dir(a)
['__add__', '__class__', '__contains__', '__delattr__', '__doc__',
'__eq__', '__format__', '__ge__', '__getattribute__', '__getitem__',
'__getnewargs__', '__getslice__', '__gt__', '__hash__', '__init__',
'__le__', '__len__', '__lt__', '__mod__', '__mul__', '__ne__', '__new__',
'__reduce__', '__reduce_ex__', '__repr__', '__rmod__', '__rmul__',
'__setattr__', '__sizeof__', '__str__', '__subclasshook__',
'_formatter_field_name_split', '_formatter_parser', 'capitalize',
'center', 'count', 'decode', 'encode', 'endswith', 'expandtabs', 'find',
'format', 'index', 'isalnum', 'isalpha', 'isdigit', 'islower', 'isspace',
'istitle', 'isupper', 'join', 'ljust', 'lower', 'lstrip', 'partition',
'replace', 'rfind', 'rindex', 'rjust', 'rpartition', 'rsplit', 'rstrip',
'split', 'splitlines', 'startswith', 'strip', 'swapcase', 'title',
'translate', 'upper', 'zfill']

我已经完成了下面的函数(get_object_functions)，它接收一个对象(object_)作为它的参数，并返回一个包含对象类中定义的所有方法(包括静态方法和类方法)的列表(函数):

def get_object_functions(object_):
    functions = [attr_name
                 for attr_name in dir(object_)
                 if str(type(getattr(object_,
                                     attr_name))) in ("<class 'function'>",
                                                      "<class 'method'>")]
    return functions

好吧，它只是检查类的属性类型的字符串表示是否等于“<class 'function'>”或“<class 'method'>”，然后将该属性包含在函数列表中，如果那是True。

Demo

class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age

    def introduce(self):
        print(f'My name is {self.name}')

    @staticmethod
    def say_hi():
        print('hi')

    @classmethod
    def reproduce(cls, name):
        return cls(name, 0)


person = Person('Rafael', 27)
print(get_object_functions(person))

输出

['__init__', 'introduce', 'reproduce', 'say_hi']

可以创建一个getAttrs函数，该函数将返回对象的可调用属性名

def getAttrs(object):
  return filter(lambda m: callable(getattr(object, m)), dir(object))

print getAttrs('Foo bar'.split(' '))

那就回来

['__add__', '__class__', '__contains__', '__delattr__', '__delitem__',
 '__delslice__', '__eq__', '__format__', '__ge__', '__getattribute__', 
 '__getitem__', '__getslice__', '__gt__', '__iadd__', '__imul__', '__init__', 
 '__iter__', '__le__', '__len__', '__lt__', '__mul__', '__ne__', '__new__', 
 '__reduce__', '__reduce_ex__', '__repr__', '__reversed__', '__rmul__', 
 '__setattr__', '__setitem__', '__setslice__', '__sizeof__', '__str__', 
 '__subclasshook__', 'append', 'count', 'extend', 'index', 'insert', 'pop', 
 'remove', 'reverse', 'sort']

如果你特别需要方法，你应该使用inspect.ismethod。

对于方法名:

import inspect
method_names = [attr for attr in dir(self) if inspect.ismethod(getattr(self, attr))]

对于方法本身:

import inspect
methods = [member for member in [getattr(self, attr) for attr in dir(self)] if inspect.ismethod(member)]

有时检查。isroutine也很有用(对于内置，C扩展，没有“binding”编译器指令的Cython)。

没有可靠的方法可以列出所有对象的方法。Dir (object)通常是有用的，但在某些情况下，它可能不会列出所有的方法。根据dir()文档:“使用参数，尝试返回该对象的有效属性列表。”

检查方法是否存在可以通过callable(getattr(object, method))来完成，就像前面提到的那样。

这里有一个很好的一行代码(但也会得到属性):

print(*dir(obj), sep='\n')
