Making code easier to use
>>> from Bio import SeqIO
>>> memory_dict = SeqIO.index("in.gb", "genbank")
>>> memory_dict.keys()
[’Z78484.1’, ... ’Z78471.1’]
>>> seq_record = memory_dict["Z78475.1"]
>>> print seq_record.description
P.supardii 5.8S rRNA gene and ITS1 and ITS2 DNA
>>> seq_record.seq
Seq(’CGTAACAAGGTTTCCGTAGGTGAACCTGCGGAAGG...GGT’,
IUPACAmbiguousDNA())
