How to Efficiently Split Strings in Python Using Multiple Operations in One Line

When working with file paths in Python, you might often find yourself needing to extract specific parts of the path, particularly the file name without its extension. This can seem like a simple task, but doing so in an efficient manner—especially in a single line of code—may require some clever use of Python's built-in functionality. In this post, we'll explore how to handle this and provide you with a step-by-step guide to achieving your desired output.

The Problem

Let’s break down the scenario; you have the following file path:

Your goal is to extract just 43et1 from this file path—which means you want to get the filename without its .jpg extension.

Initially, you might attempt the following code:
