How to asign one column to another column in cif.Document?

[hlvlad]

Hello,

Given CIF Table, how to asign one column to another column?

auth_seq_col = cif_block.find_values('_atom_site.auth_seq_id')
label_seq_col = cif_block.find_values('_atom_site.label_seq_id')

if auth_seq_col is not None and label_seq_col is not None:
   (?)for i, value in enumerate(auth_seq_col):
              label_seq_col[i] = value

The simplest way is to do it while iterating over cif.Table:

for row in cif_block.find('_atom_site.', ['auth_seq_id', 'label_seq_id']):
    row[1] = row[0]
