[BioPython] blast for more than one sequence

[Muthuraman, Manickam]

hai all

I have tried to blast through the internet, i can suceed with one sequence but i need to blast more than one sequences through internet.

for example
m_cold.fasta has 5 sequences but the code which is been stated in book can do only for the first sequence and rest it does not

file_for_blast=open('m_cold.fasta','r')
f_iterator=Fasta.Iterator(file_for_blast)
#does the above line loop through the file and get each sequence for blasting, if so let me know how

i also tried another way but i do not want to confuse you by sending the whole script.
