Using Python in UniVerse

I have used Python in UniData to produce , populate and read back xlsx spreadsheets and attached them to emails. There are a couple of python packages you can use to assist with the xlsx side. It’s pretty simple.

You can use shipped python as normal one, example:
```
LD_LIBRARY_PATH=$UVHOME/python/lib PYTHONHOME=$UVHOME/python $UVHOME/python/bin/python3 -m pip install openpyxl
```

It will install openpyxl library from pip for working with excel and it will be available for python inside universe itself. You can setup python in your system however you like.
