Add More Detailed Variable Descriptions to Docstrings

While the current docstrings are helpful in understanding the functionality of the code, they lack adequate descriptions for variables used within the code. This omission can make it challenging for users or contributors to fully understand the role each variable plays.

To address this issue, I propose adding detailed descriptions for each variable within the existing docstrings.
This will make it easier to understand not only the function but also the context in which each variable is used, improving the code's readability and maintainability.
