python connection commit

in this tutorial, you'll learn about establishing a connection to a database using python, executing sql queries, and committing changes to the database. we'll be using python's built-in sqlite3 module as an example, but the principles discussed here apply to other database management systems as well.
before you begin, make sure you have python installed on your system. you can download it from python's official website. additionally, ensure you have a basic understanding of sql (structured query language) and databases.
since we're using the built-in sqlite3 module, there's no need to install anything separately.
first, let's establish a connection to the sqlite database. if the database doesn't exist, sqlite will create one for us.
a cursor object allows us to execute sql queries against the database.
now, you can execute sql queries using the cursor object. let's create a table named employees.
next, let's insert some data into the employees table.
transactions are a series of operations that should be treated as a single unit of work. if any operation fails, the entire transaction should be rolled back.
finally, close the connection to the database when you're done working with it.
that's it! you've learned how to establish a connection to a sqlite database, execute sql queries, commit changes, perform transactions, and close the connection using python. these principles can be applied to other database management systems as well, with appropriate modifications.
