Since nobody has mentioned about the official reference of SQLite, I think it may be useful to refer to it under this heading:

https://www.sqlite.org/cli.html

You can manipulate your database using the commands described in this link. Besides, if you are using Windows OS and do not know where the command shell is, that is in the SQLite's site:

https://www.sqlite.org/download.html

After downloading it, click sqlite3.exe file to initialize the SQLite command shell. When it is initialized, by default this SQLite session is using an in-memory database, not a file on disk, and so all changes will be lost when the session exits. To use a persistent disk file as the database, enter the ".open ex1.db" command immediately after the terminal window starts up.

The example above causes the database file named "ex1.db" to be opened and used, and created if it does not previously exist. You might want to use a full pathname to ensure that the file is in the directory that you think it is in. Use forward-slashes as the directory separator character. In other words use "c:/work/ex1.db", not "c:\work\ex1.db".

To see all tables in the database you have previously chosen, type the command .tables as it is said in the above link.

If you work in Windows, I think it might be useful to move this sqlite.exe file to same folder with the other Python files. In this way, the Python file writes to and the SQLite shell reads from .db files are in the same path.
