How do I delete all records in a table instead of having to iterate
through all the data using Python and deleting by ID?

Or just drop the table and then recreate it (minus the data).

Here is the "standard" way.

I'm very glad you "quoted" the word standard, because
TRUNCATE is not very standard in relational database
theory (and SQL).

For example, ON DELETE triggers aren't invoked, and
auto_increment counters are reset. That can easily ruin
the integrity of a database. So, TRUNCATE is potentially
very dangerous.

I would consider it more a DBA tool than a programming
statement, only to be used by experts. That's also the
place it has in the SQL99 standard and in PostgreSQL.

Though slower, the real standard way is DELETE FROM
tablename;
