Creating Dynamic Lists and Worksheets in Python Using Dictionaries

Managing dynamic data can be challenging, especially when you're trying to create multiple lists and worksheets based on the values of an existing list. In this guide, we will explore a clear solution to creating lists and worksheets dynamically in Python. Whether you're dealing with test cases, results, or screenshot paths, we've got you covered!

The Problem

Imagine you have a list of tasks:

From this list, you need to create several new variables:

Individual lists for each task (like testcases_backup, results_backup, and screenshot_paths_backup),

New worksheets (e.g., worksheet1, worksheet2, etc.) associated with each task.

The goal is to automate this process so that if you add more tasks to your initial list, your code adjusts accordingly. The challenge is figuring out how to implement this effectively in Python.

The Solution

Step 1: Generate the List

First, we'll need a function that generates our main list. You likely already have this, but for completeness, we'll define it:

Step 2: Initialize the Dictionary of Lists

Instead of creating individual lists with standalone names, we can use a dictionary to handle our lists. This approach keeps everything organized and easily accessible.

Step 3: Creating the Lists and Worksheets

Next, we will set up a function to process the elements in our generated list. This function will append test cases, results, and screenshot paths as needed.

Step 4: Putting It All Together

Now, let's see how to combine all these pieces into a cohesive structure. Here is the complete code:

Understanding the Structure

You may wonder how the data is stored. The dictionary maintains lists of lists, allowing you to keep track of all outputs neatly. After adding one test case, your structure looks like this:

This way, as you continue to run tests, your data grows, and you can easily access the test items, results, and screenshot paths through the dictionary.

Conclusion

Using a dictionary to manage dynamic lists and worksheets is a powerful technique in Python. This approach not only helps in keeping your code organized but also makes it adaptable for changes in input data. Whether you're logging results or organizing test cases, this solution streamlines the process.

By automating the creation of lists and worksheets, you can focus on what matters—effectively analyzing your data!
