Hi! I'm looking at a crime dataset and I want to create a query that finds the block of each district (there are 22 total) with the highest number of gun-related crimes. I think I have to create a subquery but not really sure how to do this. I tried creating an alias with mycount but that also didn't work.

My most successful attempt is:
    cursor.execute("SELECT block, count(block) AS MYCOUNT FROM crimes WHERE DESCRIPTION::text LIKE %s GROUP BY block ORDER BY count(block) DESC",[gun])
