Access Class Name From a Class Method

assuming the simple case where Foo is

class Foo:
    def some_func(self):
        print('hellow world')

I only have access to the variable func where func is :

func = Foo.some_func

I am trying to get the Foo class name from the variable func

func
Out[6]: <function __main__.Foo.some_func>
func.__class__.__name__
Out[7]: 'function'

I am expecting to get Foo is there anyway to do that?

Python 3 solution:

def get_class_name(func):
    return func.__qualname__.split('.')[0]

__qualname__ method actually prints Foo.some_func for func.

Splitting the string by . and taking the first element, it should do the job.

Python 2 & 3 solution:

def get_class_name(func):
    return func.__str__().split('.')[0].split()[-1]

Edit:

In Python 3, func.__str__() prints <function Foo.some_func at 0x10c456b70>.

In Python 2, func.__str__() prints <unbound method Foo.some_func>.
