Up to this point with our SQLite and Python tutorial series, you have been shown how to create a database, a table, how to insert data, and how to read data. In this tutorial, we’re going to talk about how to modify existing data, as well as how to delete data.

It is important to note that there are no undos when it comes to SQL. Once you delete something, or once you modify it, that’s that. Take your time, read over, and re-read your queries before you do them!

    Probably you don't need this anymore, but if someone will see this video and comment, I suppose that the c.fetchall() returns a queue, so every time that you get a row out from this queue, you are deleting it from the memory or something like that. Just google queue in python for more info; i'm not expert in this, but this is interesting to know.

    One line print without pep8 screams:
    print(*c.fetchall(), sep=“n”)

    Great tutorials, as always. Just wondering why at 4:11 three of the 8.0's you selected did not get replaced with 99.0's.

    Maybe appending the database values to the variable DATA would've helped i think so

    Why not send 'c' to populate mars instead of sending our own precious adventurers to their doom?
