What is SQLite?
SQLite is a popular, lightweight, and self-contained relational database management system. It is widely used due to its simplicity, efficiency, and easy integration. Unlike client-server database management systems, SQLite is serverless and operates directly from the database files, making it easy to set up and use, especially in embedded systems and small-scale applications.
Why use SQLite with Python?
SQLite is employed with Python for its user-friendly integration, catering to small to medium-scale applications requiring local data storage. Its seamless compatibility and minimal setup complement Python’s simplicity, allowing developers to efficiently manage databases.
Is SQLite good for Python?
SQLite is well-suited for use with Python. It integrates seamlessly with Python due to its simplicity and efficiency, making it an excellent choice for applications that require a local database. With Python’s built-in support for SQLite and the availability of the SQLITE3 module, developers can easily create, manipulate, and manage SQLite databases, enhancing data storage and retrieval capabilities within Python applications.
Tutorial Python – Using SQLite database
Establish a connection to the database.
If the file database file does not exist, the connect function will create it.
Create a cursor object.
Create a table in the database using the cursor.
This creates a table in the connected SQLite database. It defines the table’s structure with five columns: ID as the primary key set to auto-increment, NAME, SPECIAL_MOVE, SS_LEVEL and EYE_COLOR.
Insert data in the table.
There are multiple ways to insert data in the table.
Save changes to the table.
Retrieve the information stored within the table.
Display the information retrieved as a tuple.
Here is the command output.
Display the information retrieved as a formatted string.
Here is the command output.
Optionally, return the data in dictionary format, which will allow accessing the values using the keys.
Here is the command output.
Close the connection to the database.
Here is the complete Python script.
Conclusion
Optimize data management in Python with SQLite. Simplify data storage, retrieval, and manipulation, enabling efficient workflow and data-driven insights. Enhance your data handling capabilities effortlessly.
