[FIXED] How to extract data from json?

Issue

With following code I extract this output but how to extract the all ['_id'] from the output?

def geneinfo(gene):
    url = 'http://mygene.info/v3/query?q='+gene
    r = requests.get(url)
    return r.json()['hits']

geneinfo('cdk2')

The output:

Solution

If data is your output from the question you can do:

out = [d["_id"] for d in data]
print(out)

Prints:

[
    "1017",
    "12566",
    "362817",
    "109992509",
    "115358851",
    "101675892",
    "105531943",
    "ENSLCAG00010025960",
    "ENSLCAG00010026017",
    "ENSLOCG00000004109",
