I would like to receive consensus sequences in turn for each sub-list. I tried this way:

from Bio.Align import AlignInfo
for z, _ in enumerate(pp):
    summary_align = AlignInfo.SummaryInfo(pp[z])
    consensus = summary_align.dumb_consensus()
    print(consensus)

But I get the error:

 File "C:\...", line 93, in <module>
consensus = summary_align.dumb_consensus()

 File "C:\...", line 77, in dumb_consensus
con_len = self.alignment.get_alignment_length()

AttributeError: 'list' object has no attribute 'get_alignment_length'

Thanks for any answer.
