Hello!

I have a Python/Larch related question. I have been developing some python script via jupyter and incorporating Larch as a module. I was able to read an athena prj file with the following code

import larch as lc

athena_prj = lc.io.read_athena(prjfilename)

Python stores this object as a 'Group' object with each spectrum being an instance. I would like to go through more processing with all spectra.

Example:

for spectrum in athena_prj:

lc.xafs.find_e0(spectrum.energy, spectrum.mu, group = spectrum)

This does not work since the 'Group' object is not iterable. I tried to look up some other built-in functionality with python, but couldn't find an efficient way other than manually typing out each spectrum (athena_prj.spectrum1, athena_prj.spectrum2, .... etc). Is there any built-in functionality in larch that can iterate this 'Group' object?

Any help would be appreciated. Thank you for your time!
