Get gene sequence for oragnism using python

Question

[Ahmed]

Hi,

If I have the Genus & Species how can I use them in python code to get a gene sequence. For example:

SpecCode: 64588
Genus: Aapticheilichthys
Species: websteri

How can I use these date to get "Cox1" sequence in python ?

Thanks in advance

You can use this as a base to start!

EFetch: Downloading full records from Entrez

can you explain more if you can ?

EXample of using biopython api to download fasta/genbank files from NCBI You better get one ncbi account and then use the email you login in. Need to choose the database "nucleotides" if you need dna/sequence data. Need a ID for the gene you need data. Need to choose the type of file you need (ig. genbank) etc..
