## Connecting to MySQL Database and Loading Data from a CSV File

In this tutorial, we demonstrate how to connect to a MySQL database and load data from a CSV file using Python. This step-by-step guide covers setting up the connection, creating a table, and importing data efficiently.

### Overview:

1. **Setup and Environment Variables**: Learn how to configure your working directory and retrieve database connection properties from environment variables. This ensures a secure and flexible setup for database connections.

2. **Establishing a Database Connection**: Understand how to use the `pymysql` library to connect to your MySQL database. We guide you through setting up connection properties like host, user, password, and database name.

3. **Creating a Temporary Table**: Discover how to drop an existing table and create a new one using SQL queries. This section covers defining the table structure, including columns for `id`, `email`, and `password`.

4. **Executing SQL Queries**: Learn the process of executing SQL queries to drop and create tables in your MySQL database. We explain how to commit these changes to ensure they are saved.

5. **Loading Data from a CSV File**: Watch as we demonstrate how to load data from a CSV file into the newly created table. This includes specifying the file path, field delimiters, and line terminators, and handling the header row appropriately.

6. **Closing the Database Connection**: Finally, we show you the importance of closing the database connection to free up resources and ensure the stability of your database operations.
