How to Get a Function Name as a String?

So, you want to know how to get a function's name as a string? Maybe you're working on some fancy Python code and you need to dynamically retrieve the name of a function. Or perhaps you're just curious and want to know if it's even possible. Well, you're in luck! In this blog post, we'll address this common issue and provide easy solutions for you.

The Problem 🤔

Let's take a closer look at the example you provided:

def foo():
    pass

>>> name_of(foo)
"foo"

In this scenario, name_of is a hypothetical function that we wish existed to give us the name of foo. Unfortunately, Python doesn't have a built-in function to directly get the name of a function. But fear not! We have a few workarounds that can help us achieve this.

Solution 1: __name__ Attribute 😎

One way to get the name of a function is by using the __name__ attribute. This attribute holds the name of the function as a string. Here's how you can use it:

def foo():
    pass

name = foo.__name__
print(name)  # Output: "foo"

By accessing the __name__ attribute of the function, we can obtain its name. It's simple, straightforward, and doesn't require any external libraries.

Solution 2: inspect Module 🕵️‍♀️

If you're looking for a more versatile solution, you can make use of the inspect module. This module provides several functions and classes that help you gather information about live objects, including functions.

First, we need to import the inspect module:

import inspect

Now, let's see how the inspect module can help us:

def foo():
    pass

name = inspect.getframeinfo(foo.__code__).function
print(name)  # Output: "foo"

By using the getframeinfo function from the inspect module, we can retrieve information about the code frame where our function is defined. From this information, we can extract the function's name.

Call-to-Action: Your Turn! 🚀

That's it! Now you know two simple ways to get a function's name as a string in Python. Whether you prefer using the __name__ attribute or the inspect module, you have the tools to tackle this problem.

So, why not try it out yourself? Write a little snippet of code using one of the methods we discussed and see if you can successfully extract a function's name as a string. Don't forget to share your experience in the comments below! We'd love to hear from you.
