Parsing Genbank Files

The record that was parsed using SeqIO above is a Python object. Its features attribute is a list of BioPython SeqFeature objects. Each feature contains a list of "qualifiers", which contain information such as the locus tag, gene (if available), db_xrefs, etc. To see the qualifiers for a CDS feature in the Genbank record, we can run this code:
