How can I parse a class attribute for its name?

Question

I apologize if my terminology is incorrect. I am trying to get the name of the function from an API return. For example, the following is what is returned from an API. How do I get the name, the_function?

my_variable = <Function the_function(str,int,uint)>

The type of the above is:

type(my_variable) = <class 'the_class.utils.datatypes.the_function'>

If I only have access to what I have shown, how to I the text string the_function? Is there an easy way to do it besides turning it into a string and using regex or something similar?

If I do `my_variable.__name__`, I get 'the_function' object has no attribute '__name__' — python_crypto_questions, Jan 04 '19 at 08:46
Did you tried to print its `dir` to see what all are its attributes? — Abdul Niyas P M, Jan 04 '19 at 08:48
@Abdul Niyas P M Ahhh that has the answer. There is a `function_identifier` in the `dir` that gives me what I need. Is this normal? — python_crypto_questions, Jan 04 '19 at 08:52
You can't do `my_variable = `, this is not correct syntax. `` means nothing to python on its own — Aykhan Hagverdili, Jan 04 '19 at 08:52
@python_crypto_questions Yes. Always use [dir](https://docs.python.org/3/library/functions.html#dir) if you have no idea what all are the attributes does the object have. — Abdul Niyas P M, Jan 04 '19 at 09:00

Use __name__ argument:

def yourfunction():
    pass

print(yourfunction.__name__)

Then now you'll get expected output.

If you have access to that function through literally any variable, you can use .__name__:

 >>> def the_function():
...     pass
... 
>>> the_function.__name__
'the_function'
>>> foo = the_function
>>> foo.__name__
'the_function'

@python_crypto_questions What's `variable` in that context? – Aykhan Hagverdili Jan 04 '19 at 08:48
