sqliteHow can I use SQLite to create a Kivy app?

SQLite is a popular open source database engine that can be used to create Kivy apps. It is lightweight, self-contained, and requires no external dependencies. To use SQLite with Kivy, you need to install the sqlite3 module.

The following example code creates a Kivy app that uses SQLite to store data:

import kivy
from kivy.app import App
from kivy.uix.button import Button
import sqlite3

conn = sqlite3.connect('my_database.db')
c = conn.cursor()

c.execute("CREATE TABLE IF NOT EXISTS users (name text, age integer)")

c.execute("INSERT INTO users VALUES ('John', 25)")

c.execute("SELECT * FROM users")
print(c.fetchall())

class MyApp(App):
    def build(self):
        return Button(text='Hello World')

if __name__ == '__main__':
    MyApp().run()

Output example

[('John', 25)]

The code above does the following:

1. Imports the kivy and sqlite3 modules.
2. Connects to an SQLite database called my_database.db.
3. Creates a table called users with two columns: name and age.
4. Inserts a row into the users table.
5. Queries the users table and prints the results.
6. Creates a Kivy app with a single button.
7. Runs the Kivy app.
