Understand how to work with databases in Python from "summary" of Python For Dummies by Stef Maruch,Aahz Maruch
To work with databases in Python, you need to use a database interface module. Several such modules are available, including the Python standard module called DB-API. You can use DB-API to communicate with relational databases that support SQL (Structured Query Language). To use DB-API, you first import it, as you would with any other module in Python. Next, you establish a connection to the database by calling the `connect()` method of the module, passing it the necessary connection parameters, such as the database name, user name, password, and host. Once the connection is established, you create a cursor object by calling the `cursor()` method on the connection object. The cursor object is used to execute SQL statements and retrieve results from the database. To execute SQL statements, you call the `execute()` method on the cursor object, passing it the SQL statement as a string. You can also pass p...
