I love Python/am good at it but I don’t understand SQL

Hi, I need to get better at SQL. I’ve been doing Leetcode for 1.5+ months now and barely any progress.

I love python and am great at it. I don’t understand why SQL is difficult for me to get a grasp on.

Any good Youtube channels/websites/resources to understand/get better at SQL?

I want to switch jobs later this year and need to get better at SQL asap. Thanks!
