Maybe not, but it's still worth being aware of. Even if today your
strings will never include apostrophes, it's still important to
understand the risks of SQL injection and properly escape them before
inserting them into an SQL statement. Just docket the information in
the back of your mind "Don't use pickle with untrusted data" and move
on. :)
