#gene_id = [line.strip() for line in open("C:/name/MyDocuments/numbers", 'r')]

gene_id = ["ENSG00000196498", "ENSG00000157764", "ENSG00000139618", "ENSMUSG00000041147"]

for gene in gene_id:
    new_gene = gene
    response = requests.get("http://rest.ensembl.org/lookup/id/{}?content-type=application/json".format(new_gene))
    json_data = response.content.decode("utf-8")
    data = json.loads(json_data)
    print data['id'], data['display_name'], data['species']

I'd do #14
print data.get('id', 'not found'), data.get('display_name', 'not found'), data.get('species', 'not found')
