Prova
Ask anything. Every explanation is backed by code that actually runs — no hallucinated statistics, no unverifiable claims.
Meet Prova — the tutor that can't bluff
Hi, I’m Prova. Ask me anything about R or Python data science — I answer from Datanovia’s lessons, with runnable code and a link to the source. Your first answers are on the house. Reading a lesson? Ask me right there and I’ll debug your code on your own data. The runtime is the judge.
