Off topic:extract fasta sequence using fasta header with python 3

Question

[ddowlin]

Hi all,

I have a list of fasta headers and a corresponding multi fasta file.

Using python3 I would like to iterate through my list of ids and extract the matching fasta sequence form my fasta file. I, then, want to write each header and sequence to its own fasta file.

What is the best approach using python3?

Many thanks.
