[BioPython] parsing the blastoutput and printing the alingment

[Muthuraman, Manickam]

I am new to python 

I am getting error in parsing blastoutput more over the same problem was been addressed by Michiel De Hoon but i could not clear...here is the error what i am getting.

first i got error when i typed b_record=b_parser.parse(blast_out) as michiel suggested i changed to 
b_record=b_parser.parse(blast_out)
Traceback (most recent call last):

from Bio.Blast import NCBIStandalone
from Bio.Blast import NCBIXML
b_parser=NCBIXML.BlastParser()
b_iterator1=NCBIStandalone.Iterator(blast_out,b_parser)
for alignment in b_iterator1.alignments:
    for hsp in alignment.hsps:
        print 'seq:',alignment.title
    
Traceback (most recent call last):
  File "<input>", line 1, in ?
AttributeError: Iterator instance has no attribute 'alignments'


how do i print the title.alignment and so on.....from the blast output file
thanks in advance
