Minor change to Biopython SeqIO example

[peterjc]

In Scientific_python/Skimage_biopython.ipynb rather than:

from Bio import SeqIO
for item in SeqIO.FastaIO.FastaIterator(open('data/sweet_taste_receptor.txt', 'r')):
    print(item)

our documentation would use:

from Bio import SeqIO
for item in SeqIO.parse('data/sweet_taste_receptor.txt', 'fasta'):
    print(item)

(I'd actually use double quotes - your examples are inconsistent on this point)

Key points: Emphasises file-format neutral API (makes switching file format later much easier, closer to the usage you followed for AlignIO) and also will take care of closing the file handle internally.

Hi Peter,

Thanks for your suggestion. Just using the parse function in SeqIO is more general and thus more didactic.

I also made the quotation consistent throughout the examples.

Cheers,

Michiel
