python - Create List from List of Key-Values -

-

given json structure below, want grab data item, pull 1 of values link out randomly.

using random - familiar grabbing random value list. i'm stuck how make list list. see code below json. 

item0:     0     caption: "caption 0"     link: "www.item0.com"     type: "type0"      1     caption: "caption 1"     link: "www.item1.com"     type: "type1"

python: 

chosen_item = "item0" firebase = firebase.firebaseapplication('https://app.firebaseio.com') result = firebase.get(chosen_item, none)  if result:    in result:      result_link = (i['link'])     print result_link

the if-statement loops through , returns link's in item unicode type. how make list this? ( result_link ) 

chosen_item = "item0" firebase = firebase.firebaseapplication('https://app.firebaseio.com') result = firebase.get(chosen_item, none)  if result:    links = []   in result:      links.append(i['link'])
