What can I do if I want to export attributes in Group in batch to excel?

[zhangnaichi2020]

I used Larch to calculate multiple attributes (e.g. convolution, deconvolution ...) of many materials (e.g. CrOH3, Cr_Foil, CrCl3_6H2O, Cr_illite ....) and add them to the Group of each material.
Take CrOH3 as an example, dir(CrOH3) returned ['energy', 'mu', 'flat', 'convolution', 'deconvolution', 'noise'], what can I do if I want to export these attributes to excel in batch?

I have tried locals() in python like:

names = locals()
species = ['CrOH3', 'Cr_Foil', 'CrCl3_6H2O', 'Cr_illite']
attrs = ['energy', 'mu', 'flat', 'convolution', 'deconvolution', 'noise']
df = pd.DataFrame()
for i in species:
    for attr in attrs:
        df['{}.{}'.format(i, attr)] = names[i].names[attr]

or

for i in species:
    for attr in attrs:
        df['{}.{}'.format(i, attr)] = names['{}.{}'.format(i, attr)]

but all failed.
Thank you in advance for your help and I am looking forward to your reply~
