PandasdrillAbout Pandasdrill
Pandasdrill is Python and pandas practice exercises that run in your browser. It is one of the Dravari drill sites, a family of practice tools built on the same idea: the fastest way to learn a skill you use at a keyboard is to do it, on a live tool, with instant checking, until it is a reflex.
How the exercises work
Look at the data: Each exercise shows its tables, so you know the columns and values before you start. Write pandas: Type in the editor and press Run to see your result as a table, with print output and readable errors. Check it: Wrong type, wrong shape, wrong columns, the first value that differs, or code that only fits the sample. Hints and a reference solution follow.
Every exercise is checked automatically against the expected result, not against a fixed answer string, so a correct approach passes even when it is written differently from the reference solution. If a check ever seems unfair there is a report link under it, and reports are read.
Who makes it
Pandasdrill is made and operated by Dravari, LLC, a Delaware limited liability company based in Wilmington, Delaware, USA. The sites are built and maintained by a small team; there is no outside funding and no advertising on the practice pages. Revenue comes from Pro subscriptions, which is what keeps the free exercises free.
