Read multi-fasta into Python and search by nucelotide

Question

[prityreem1]

I want to read a multi fasta file and trying to convert it into array. I want to search on specific SNP in the sequence. Is there any way to read the sequence char by char in python

You should put a little more effort into your question including giving more detail about your question and what you have tried so far. You should also edit the title to be more specific than just 'bioinformatics'.
