Python How to get function name?

In this tutorial, we are going to learn how to get the function name in Python. Getting the name any function is a straightforward thing. We have two different ways for Python2 and Python3. Let's see both of them.

Python2

Every function in Python2 has a property called func_name that gives you the name of the current function. Let's see an example. Make sure you are using Python2 while executing the following example.

Example

# defining a function
def testing_function():
   """
      This is a simple function for testing
   """
return None
print("Function name is (Python2) '{}'".format(testing_function.func_name))

Output

If you execute the above program, then you will get the following result.

Function name is (Python2)'testing_function'

Python3¶

The function property func_name is deprecated in Python3. We will get the name of the using property __name__ of the function. Let's see an example. Make sure you are using Python3 while running the following code.

Example

# defining a function
def testing_function():
   """
      This is a simple function for testing
   """
return None
print(f"Function name is (Python3) '{testing_function.__name__}'")

Output

If you execute the above program, then you will get the following result.

Function name is (Python3) 'testing_function'
