How to Access the Function Name From Within the Function in Python?

Finding Function Name Within the Function

Programmers often need to know the name of the function they are currently executing, especially when dealing with dynamic programming or introspection tasks. How can you access the function's name from within the function itself?

Utilizing the Inspect Module

The inspect module in Python provides insights into the current stack frame and allows us to determine the function name at runtime.

Solution

<code class="python">import inspect

def foo():
    print(inspect.stack()[0][3])  # prints the name of the current function
    print(inspect.stack()[1][3])  # prints the name of the caller function

foo()</code>

Output

foo
<module_caller_of_foo>

The code uses the inspect.stack() function to retrieve information about the current stack frame. The first element of the stack represents the current frame, and the third element contains the function name.

By understanding this technique, programmers gain better control over their code and can improve its maintainability and flexibility.
