The expression "safe=True" is an optional keyword argument being passed to "create_tables". By setting it to True, the create table query will include an IF NOT EXISTS clause. This prevents an error from occurring if the table already exists in the database.

This information can be found using the link to Peewee query methods as provided in the "Teacher's Notes" section.
