Check Names pointing to Python Object

How can I get a list of all the names that point to a Python object?

import my_function from example

a = my_function
b = my_function

get_names(my_function)
[a, b]

Edit: The goal is to help find how to monkey patch an object that is loaded in an unknown way.

See below (use globals and make sure you do not return the function itself)

from example import my_function

def get_names(func):
  result = []
  for k,v in globals().items():
    if v == func and k not in str(v).split():
      result.append(k)
  return result



def foo():
  pass

a = my_function
b = my_function
c = foo

print(get_names(my_function))

example.py

def my_function():
  pass

output

['a','b']

Search the global namespace for objects matching via identity, and report the keys (names).

def my_func():
    pass

a = my_func
b = my_func

def get_names(x):
    for k, v in globals().items():
        if v is x:
            yield k

print(list(get_names(my_func))) #prints ['my_func', 'a', 'b']
