## uproot

As opposed to {ref}`rdataframe`, let's go to the other end of the spectrum: ROOT I/O
without using ROOT. The Python [uproot](https://github.com/scikit-hep/uproot4) 
package reads ROOT files using
only Python and numpy. It's particularly handy if you were already a
Python expert before taking this ROOT tutorial, and would rather not
have to touch ROOT again if you can help it.

I've installed uproot in the Python 3 installations available at Nevis.

## coffea

The [coffea](https://coffeateam.github.io/coffea/) package is column-based analysis system specifically designed
for high-energy physics. I think of it as a Python-only equivalent to
{ref}`RDataFrames <rdataframe>`.

Hopefully your use of ROOT data will be more rational.
