SQL and Python Certifications for Financial Domain

Hello all, a query unrelated to CFA.

I have given the CFA L2 recently. So before I start the preparation for L3 (Or L2 again !!! ), in the meantime I am planning to learn/enhance few technical skillsets. Can someone please suggest good certifications/courses in SQL and Python (with financial application).

I have knowledge of basic SQL. I can write basic queries with inner and outer joins but no experience with macros.
