How to get the function name as string in Python?

Question

In Python, How do I get the function name as a string without calling the function?

def my_function():
.
.
.


print get_function_name_as_string(my_function) # my_function is not in quotes
output => "my_function"

is this available in python? if not, any idea how to write get_function_name_as_string in python?

Answer 1

my_function.func_name

There are also other fun properties of functions. Type dir(func_name) to list them. func_name.func_code.co_code is the compiled function, stored as a string.

import dis
dis.dis(my_function)

will display the code in almost human readable format. :)

Answer 2

my_function.__name__

Using __name__ is the preferred method as it applies uniformly. Unlike func_name, it works on built-in functions as well:

>>> import time
>>> time.time.func_name
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
AttributeError: 'builtin_function_or_method' object has no attribute 'func_name'
>>> time.time.__name__ 
'time'

Also the double underscores indicate to the reader this is a special attribute. As a bonus, classes and modules have a __name__ attribute too, so you only have remember one special name.
