Converting a String Representation of a List to a Dictionary in Python

In Python programming, you might encounter scenarios where you need to convert data from one structure to another, for example, transforming a string representation of a list into a dictionary. This can be particularly useful when working with configurations, processing JSON data, or integrating with external systems such as FreeRADIUS. This guide explains how you can achieve this conversion with Python.

Understanding the Problem

Assume you have a string that looks like a list of key-value pairs:
