I use ftplib in the standard libraries.

from ftplib import FTP

def grab_geneontology():
     """Function to download gene ontology file."""
     ftp = FTP('ftp.geneontology.org')
     ftp.login()
     ftp.cwd('/pub/go/ontology')
     ftp.retrbinary('retr gene_ontology.obo', 
open('gdata/gene_ontology', 'wb').write)
     ftp.quit()

if __name__ == '__main__': grab_geneontology()
