How to Add Data from an Array to PrettyTable via Columns in Python

If you're working with Python and have encountered the PrettyTable library, you might be wondering how to display your array data in a structured table format. In this guide, we're going to address a common challenge: adding data from an array to a PrettyTable using the add_row function. Let's dive into the issue and explore the solution step by step.

The Problem

Imagine you have an array filled with numbers, and you want to display them neatly in a table format. Here's a simple example of such an array:

This indicates that there's an issue with the way the columns are being added. Don't worry; we're here to help you solve this problem effectively!

The Solution

Instead of using add_column, we will use the method add_row which is more suitable for our needs. Here’s how to do it step by step:

Step 1: Prepare Your Data

To have "Number" as a label and the elements of the array as data, you need to format your data properly. This can be done by organizing the information in a list where the first item is the header (like "number") followed by its values. Here's how we can do that:

Conclusion

Using PrettyTable to visualize data from an array in Python is a straightforward process once you know the correct methods to use. Instead of struggling with add_column, apply the add_row function to organize your data into a table efficiently. With a few lines of code, you can present your arrays in a neat and professional manner.

Now it’s your turn! Use the steps outlined in this guide to tackle your own data representation projects with PrettyTable. Happy coding!
