How to change name of species in FASTA file with BioPython

Question

[Daphnia3000]

Hi I am trying to figure out a basic script to edit the names of the species in my FASTA file. I need the final product of the names to look like this:

>Homo_sapiens (FTO_NP_001073901) 
>Pan_troglodytes (FTO_XP_510968) 
>Nomascus_leucogenys (FTO_XP_003263101) 
>Pongo_abelii (FTO_NP_001126250)

Hello and welcome to biostars Daphnia3000 ,

your post is missing important information. How does your input looks like? What have tried and where did you get stuck?

As finswimmer mentioned, the minimum we need is an example of your input so we know what manipulations are needed to create your desired output.

Like others also said, we need more info to give the exact answer but I will still give it a try. I assume you have BioPython working, you can use something like this:

from Bio import SeqIO
with open("input.fa", "rU") as handle, open("output.fa", "a") as output:
    for record in SeqIO.parse(handle, "fasta"):
        newHeader = "create your new header here, maybe split() will help"
        output.write(">"+newHeader+"\n")
        output.write(str(record.seq)+"\n")
