Hi Jumana,


Please read:

    http://biopython.org/DIST/docs/tutorial/Tutorial.html#sec2

and let us know if there's anything there that you do not understand.

In particular, Biopython is a library that is written in Python,
developed by bioinformaticists, and has been heavily used and tested.
Unless you are doing something highly unusual and customized, you
should invest some time into using this library.  Reusing the work of
other people is very important to learn: it can lead to less wasted
effort.  I'm trying to head you away from wasting time writing a FASTA
parser.
