Extract amino acid sequence (with fasta header) from FGENESH tool : Python

Question

Hello,

Could everyone help me about How to extract amino acid (with fasta header) from FGENESH prediction tool?

The Output of FGENESH like this:

But I would like to extract only amino acid with some position such as; I would like to get only amino acid (in position 16356-17500) and amino acid sequence. Like this:

>FGENESH:   2   5 exon (s)  16356  -  17500    15 aa, chain +
MNKRKMKGKNILKTA

Could anyone can suggest me in python script?

Thank you advance,

grep line starting with '>' and print one line After the match

   grep '^>' -A 1--no-group-separator  input.txt
