python how to know current function name (python 현재 실행중인 함수 이름 확인)

 You can use the built-in function inspect.currentframe().f_code.co_name to get the name of the current function in Python.

import inspect 
def my_function():
    
    print(inspect.currentframe().f_code.co_name) 
my_function() # prints "my_function"

This will return the name of the function as a string. You can also use inspect.stack()[1][3] to get the name of the current function.

import inspect 
def my_function():
    
    print(inspect.stack()[1][3])
 my_function() # prints "my_function"

You can use the built-in sys._getframe() function to get the current frame in Python, and then access the f_code attribute to get the name of the current function.
import sys 
def my_function(): 
    print(sys._getframe().f_code.co_name) 
 my_function() # prints "my_function"
This method is not recommended, because sys._getframe() is an implementation detail and might not exist in all implementations of Python and also it's not recommended to use sys._getframe() as it is not a part of the public python api and it's not guaranteed to be present in all python implementations.
You can also use the function.__name__
def my_function(): 
    print(my_function.__name__) 
 my_function() # prints "my_function"
It will give you the name of the function which is calling it.
