In Python, how can you get the name of a member function's class? (5 answers)

Closed 8 years ago.

In pyton code I've got a bound method of some object. Knowing only this bound method I would like to know what is the class of that object. Is it possible?

Here is sample code:

>>> class x:
...     def method(self):
...             pass
...
>>> x
<class __main__.x at 0xb737d1ac> 
>>> x_instance = x()
>>> x_instance
<__main__.x instance at 0xb737c7cc>
>>> boundmethod = x_instance.method
>>> boundmethod
<bound method x.method of <__main__.x instance at 0xb737c7cc>>
>>> str(boundmethod)
'<bound method x.method of <__main__.x instance at 0xb737c7cc>>'

Let's assume I know only boundmethod. How to determine that the class is x?

Answer 1

If you want the name of it:

boundmethod.im_class.__name__

Or in python 3:

boundmethod.__self__.__class__.__name__
