(Python) How can I print the function name of a partial function

I am running a process where I add failed functions to a list to be retried later. I use partial for this. Now I want to print what function is being retried.

Example Code:

retry_queue = []

def foo():
    """ Try and run function_a """

    result = function_a()

    if !result:
        retry_queue.append(partial(function_a, args)

    return retry_queue


# run the foo function
foo()

# retry all the failed functions
for function in retry_queue:
    print("Now running function: %s", function)
    function()


Wanted output:

>>> Now running function: function_a
   

How can I change my code to produce the wanted result?

I tried printing the example code, but that just gave a pointer to an object of the function.

You can access the original function with the func attribute. See the docs for more information.

In case you pass regular functions, you should write a wrapper that extracts the name of partial objects or "normal" functions.

from functools import partial
from typing import Callable, Any

def callable_name(any_callable: Callable[..., Any]) -> str:
    if isinstance(any_callable, partial):
        return any_callable.func.__name__

    try:
        return any_callable.__name__
    except AttributeError:
        return str(any_callable)

Now callable_name(print) and callable_name(partial(print, "Hello,")) both return 'print'.

If you have to support other callables besides partial and functions, you can add cases to handle that.
