使用检查。Ismethod, dir和getattr

 import inspect
 class ClassWithMethods:
    
    def method1(self):
        print('method1')
    def method2(self):
        print('method2')

obj=ClassWithMethods()

method_names = [attr for attr in dir(obj) if inspect.ismethod(getattr(obj,attr))

print(method_names)

输出:

[[('method1', <bound method ClassWithMethods.method1 of <__main__.ClassWithMethods object at 0x00000266779AF388>>), ('method2', <bound method ClassWithMethods.method2 of <__main__.ClassWithMethods object at 0x00000266779AF388>>)]]

如果你只想列出一个python类的方法

import numpy as np
print(np.random.__all__)

使用检查。Ismethod, dir和getattr

 import inspect
 class ClassWithMethods:
    
    def method1(self):
        print('method1')
    def method2(self):
        print('method2')

obj=ClassWithMethods()

method_names = [attr for attr in dir(obj) if inspect.ismethod(getattr(obj,attr))

print(method_names)

输出:

[[('method1', <bound method ClassWithMethods.method1 of <__main__.ClassWithMethods object at 0x00000266779AF388>>), ('method2', <bound method ClassWithMethods.method2 of <__main__.ClassWithMethods object at 0x00000266779AF388>>)]]

试试属性__dict__。

def find_defining_class(obj, meth_name):
    for ty in type(obj).mro():
        if meth_name in ty.__dict__:
            return ty

So

print find_defining_class(car, 'speedometer') 

Python第210页

methods = [(func, getattr(o, func)) for func in dir(o) if callable(getattr(o, func))]

给出一个相同的列表

methods = inspect.getmembers(o, predicate=inspect.ismethod)

所做的事。
