A context manager: Create a context manager that handles the connection and cursor creation, as well as closing the connection when done. This way, you can use the with statement to manage the connection and cursor in your functions.

import sqlite3

DB_FILE = "your_database_file.db"

class DatabaseConnection:
    def __enter__(self):
        self.conn = sqlite3.connect(DB_FILE)
        self.cursor = self.conn.cursor()
        return self.cursor

    def __exit__(self, exc_type, exc_val, exc_tb):
        self.conn.commit()
        self.cursor.close()
        self.conn.close()

def insert_post_to_db(issue: Issue, lemmy_post_id: int) -> None:
    with DatabaseConnection() as cursor:
        cursor.execute(
            "INSERT INTO posts (issue_url, lemmy_post_id, issue_title, issue_body) VALUES (?, ?, ?, ?)",
            (issue.url, lemmy_post_id, issue.title, issue.formatted_body),
        )
