How to Get a Function Name as a String in Python

Using __name__ Attribute

Using __qualname__ is the preferred method as it applies uniformly. It works on built-in functions as well:

#!/usr/bin/python3

def my_func():
  pass

class A():
  def getName():
    pass

print(my_func.__name__)

print(A.getName.__name__)
# Python 3.3+
print(A.getName.__qualname__)

my_func
getName
A.getName

If you're interested in class methods too, Python 3.3+ has __qualname__ in addition to __name__.

Using inspect Module

The inspect module provides several useful functions to help get information about live objects such as modules, classes, methods, functions, tracebacks, frame objects, and code objects.

See the following example:

#!/usr/bin/python3

# Import module
import inspect

def my_func():
  func_name = inspect.currentframe().f_code.co_name
  print(func_name)
  pass

class A():
  def getName():
    func_name = inspect.currentframe().f_code.co_name
    print(func_name)
    pass

my_func()

A.getName()

my_func
getName

sys._getframe also works instead of inspect.currentframe although the latter avoids accessing a private function.
