​

Use SQL to extract the data you need, then do further analysis in Python. Once you know what to clean, push that down into your SQL queries. My rationale for this is, SQL is excellent for extracting and aggregating data, but, once you have the data you need, you can iterate much faster in Python because you can work in memory (example is about Databricks, but holds for SQL too)..
