I have a sqlite3 database name TEXT, favorite_friend TEXT, age INT, profession TEXT. Write me a python program that prints out the favorite friend of the youngest person who isn't anyone's favorite friend. The database is called people.db and the table is called people.

Certainly! Below is a Python program that connects to a SQLite database (`people.db`), queries the `people` table to find the favorite friend of the youngest person who isn't anyone's favorite friend, and then prints the result. ### Explanation: 1. **Connect to the Database:** - Use the `sqlite3` library to establish a connection to `people.db`. 2. **Create a Cursor:** - A cursor allows you to execute SQL commands and fetch results. 3. **Define and Execute the SQL Query:** - The query selects the `favorite_friend` from the `people` table where the person's `name` is not present in any `favorite_friend` field of the table. This ensures that the person is not anyone's favorite friend. - It orders the results by `age` in ascending order to get the youngest person first. - `LIMIT 1` ensures that only the youngest qualifying person is considered. 4. **Fetch and Print the Result:** - Retrieve the result from the executed query. - Check if a result exists and print the favorite friend accordingly. - Handle cases where no such person exists. 5. **Close the Connection:** - Always ensure that the database connection is properly closed after operations are completed. ### Python Code:

Certainly! Below is a Python program that connects to a SQLite3 database named `people.db`, queries the `people` table to find the favorite friend of the youngest person who isn't listed as anyone's favorite friend, and then prints the result. ### Step-by-Step Explanation: 1. **Import Required Modules:** - `sqlite3`: To interact with the SQLite database. - `sys`: To handle unexpected errors gracefully. 2. **Connect to the Database:** - Establish a connection to `people.db`. - Create a cursor object to execute SQL queries. 3. **Define and Execute the SQL Query:** - **Objective:** Find the favorite friend of the youngest person whose name does not appear in any `favorite_friend` field. - **Approach:** - Use a subquery to retrieve all names that are listed as someone's favorite friend. - Select persons whose `name` is **not** in the above list. - Order the results by `age` in ascending order to get the youngest first. - Limit the result to **1** to get the single youngest person. - **SQL Query:**
