Instructions to use:
- run in MySQL
create database daproj use daproj - run the sql dump provided,
daproj.sql - you can now use the database
We ask the user to input all the information we require to insert a video into our sql database.

Q2 = f"INSERT INTO upload VALUES ({accID}, {vidID})"We ask the user for the videoID of the video whose title they want to change. We then ask the user for the new title and check if its valid.
If it is valid, we update the database.

An indexed list of all comments made by that account, containing that keyword is displayed. The user is asked to enter which comment they would like to delete.
If they enter a valid index, the comment is deleted.
