Connect to the MySQL database using the `connect` method.4. Create a cursor object using the `cursor` method.5. Execute a query using the `execute` method.6. Fetch the data using the `fetchall` method.7. Iterate over the fetched data and print it.8. Close the cursor and connection using the `close` method.

Here's an example of how to read data from a MySQL database:

```pythonimport mysql.connector
