1. Preprocessing Data: Part I

First, let's get acquainted with the data we will be working with. Throughout this section, we will perform the initial set of actions to prepare the data for further analysis.

Loading the Data

Columns Overview

Removing Characters: Method 1

Removing Characters: Method 2

Checking Columns

Replacing Characters

2. Preprocessing Data: Part II

In the second section, we will continue with the preparatory tasks started in the first section and ensure the data is ready for further exploration.

Analyzing Columns

Removing and Replacing

Processing Dates

Wrong Convertation?

Proper Converting

3. Analyzing Data

After preparing the data, we will move on to some exploratory analysis. Throughout this section, we will answer several questions and uncover interesting insights.

Superficial Analysis

4. Visualizing Data

In the last section, we will use visualization tools to either confirm or reject the hypotheses we made in the previous section. We will also create visualizations of key indicators for the entire dataset.

First Look at the Data

The Most Profitable Store

Since we want to find the most profitable stores based on the given data, we need to group the observations in the df dataframe by the 'Store' column values and calculate the total (sum) of the 'Weekly_Sales' column for each group. Finally, we need to sort the resulting values in descending order.

Task

Group the observations in the df dataframe by the 'Store' column values.
Select the 'Weekly_Sales' column.
Calculate the total (sum) for each group.
Sort the resulting values in descending order (not ascending).
