Help on package Bio.SeqIO in Bio:

NAME
  Bio.SeqIO - Sequence input/output as SeqRecord objects.

DESCRIPTION
  Bio.SeqIO is also documented at SeqIO_ and by a whole chapter in our tutorial:
  
    - `HTML Tutorial`_
    - `PDF Tutorial`_
  
  .. _SeqIO: http://biopython.org/wiki/SeqIO
  .. _`HTML Tutorial`: http://biopython.org/DIST/docs/tutorial/Tutorial.html
  .. _`PDF Tutorial`: http://biopython.org/DIST/docs/tutorial/Tutorial.pdf
  
  Input
  -----
  The main function is Bio.SeqIO.parse(...) which takes an input file handle
  (or in recent versions of Biopython alternatively a filename as a string),
  and format string.  This returns an iterator giving SeqRecord objects:
  
  >>> from Bio import SeqIO
  >>> for record in SeqIO.parse("Fasta/f002", "fasta"):
  ...     print("%s %i" % (record.id, len(record)))
