Python basics tutorial sqlite cursor select fetchall method

sure! here is an informative tutorial about python basics focusing on using sqlite cursor, specifically the `select` and `fetchall` methods.

sqlite is a lightweight disk-based database that doesn’t require a separate server process to operate. it allows you to create a database and perform operations like inserting, updating, deleting, and selecting data.

in python, you can interact with sqlite databases using the built-in `sqlite3` module. to execute sql queries in sqlite databases, you need to create a cursor object.

here's a step-by-step guide on how to use the `select` and `fetchall` methods of a sqlite cursor in python:

1. import the `sqlite3` module:

2. connect to a sqlite database:

3. create a cursor object:

4. execute a select query using the `execute` method of the cursor:

5. use the `fetchall` method to retrieve all rows returned by the query:

6. iterate over the rows to process the data:

7. close the cursor and the connection after you are done:

here is a complete example demonstrating the usage of `select` and `fetchall` methods:

this tutorial covers the basics of using sqlite cursor's `select` and `fetchall` methods in python. it's a fundamental concept when working with databases in python and can be expanded upon for more complex operations.
