The hacker sneaked in an update query while entering the reviewer_id. For updating records, MySQL uses the UPDATE statement: The code passes the update query to cursor.execute(), and .commit() brings the required changes to the reviewers table. Implementations are for learning purposes only. Youll often have this data stored in some other file, or the data will be generated by a different script and will need to be added to the MySQL database. The blog will then explain the steps that you should follow if you wish to start from scratch and become efficient in Data Analytics using Python.
