Load screed, index the database, and return a dictionary-like object:
>>> import screed >>> db = screed.read_fasta_sequences('../screed/tests/test.fa')
Get the list of sequence names, sort alphabetically, and look at the first one:
>>> names = db.keys() >>> names.sort() >>> names[0] u'ENSMICT00000000730'
Retrieve that record:
>>> r = db[names[0]] >>> print r.keys() [u'description', u'id', u'name', u'sequence']
Print out the internal ID number and the name:
>>> print r.id 13 >>> print r.name ENSMICT00000000730
