Why do people use SQLAlchemy instead of MySQLdb? What advantages does it offer?
You don’t use SQLAlchemy instead of MySQLdb—you use SQLAlchemy to access something like MySQLdb, oursql (another MySQL driver that I hear is nicer and has better performance), the sqlite3 module, psycopg2, or whatever other database driver you are using.
An ORM (like SQLAlchemy) helps abstract away the details of the database you are using. This allows you to keep from the miry details of the database system you’re using, avoiding the possibility of errors some times (and introducing the possibility of others), and making porting trivial (at least in theory).
