How to Combine DataFrames in Pandas Efficiently Using concat

When working with multiple Excel files and transforming the data into a single Pandas DataFrame, you may encounter challenges, especially when you need to concatenate column-based data across different DataFrames. If you've found yourself in a conundrum while trying to merge various structured tables, you are not alone. This guide will walk you through a straightforward approach using the concat method to achieve the desired output.

The Problem: Merging DataFrames

Imagine you have two separate DataFrames, each with their unique set of columns. Your goal is to combine these DataFrames in such a way that allows you to maintain a structured dataset for further analysis. Here's what your initial DataFrames look like:

DataFrame 1 (df_1):

Now, your aim is to merge these two DataFrames into a new DataFrame, df_3, that combines the information in a well-structured manner:

Step 1: Create the DataFrames

To accomplish this, the first step is to ensure that your DataFrames are correctly set up, as shown in the previous section.

Step 2: Concatenate the DataFrames
