Converting CSV to XML with pandas Groupby in Python: A Step-by-Step Guide

Converting data from one format to another is a common task in programming, especially when dealing with CSV and XML files. If you're a novice Python developer and are facing the challenge of converting a CSV file to XML, you're in the right place. This guide will walk you through the steps needed to achieve this transformation using the pandas library and ElementTree module in Python.

Understanding the Problem

You have a CSV file that contains coupon codes along with associated amounts, and you want to convert this data into an XML format. Here's what your sample CSV data looks like:

Solution Overview

To convert the CSV data to XML, we'll use pandas for handling the data and the ElementTree in Python to create the XML structure. Here's a breakdown of the tasks we'll perform:

Read the CSV file and load the data.

Group the data by the Code (or coupon ID).

Construct the XML elements using the grouped data.

Write the constructed XML to a file.

Step-by-Step Implementation

Step 1: Read the CSV File

To start, we'll first import the necessary modules and read the CSV file.

Step 2: Load and Group the Data

We'll use a defaultdict to store the amounts associated with each coupon code. This way, we can efficiently group them.
