If a variable refers to either a function or a class method, how can I find out which one it is and get the class type in case it is a class method especially when the class is still being declared as in the given example.
eg.
def get_info(function_or_method):
print function_or_method
class Foo(object):
def __init__(self):
pass
get_info(__init__)
def bar():
pass
get_info(bar)
Update to question after the first two responses from David and J. F. Sebastian
To reemphasize a point which J.F. Sebastian alluded to, I want to be able to distinguish it when the function is being declared within the class (when the type I am getting is a function and not a bound or unbound method). ie. where the first call to get_info(__init__)
happens I would like to be able to detect that its a method being declared as a part of a class.
This question came up since I am putting a decorator around it and it gets a handle to the init function and I can't actually figure out if a method is being declared within a class or as a stand alone function
You can distinguish between the two by checking the type:
>>> type(bar)
<type 'function'>
>>> type(Foo.__init__)
<type 'instancemethod'>
or
>>> import types
>>> isinstance(bar, types.FunctionType)
True
>>> isinstance(bar, types.UnboundMethodType)
True
which is the way you'd do it in an if
statement.
Also, you can get the class from the im_class
attribute of the method:
>>> Foo.__init__.im_class
__main__.Foo
