Question

If I have some json data represented in a dictionary type, what’s the pythonic way of finding all ‘type’ nodes that match a particular value from the ‘results’ list of items?

"results" : [
   {
      "address_components" : [
         ... child elements ...
      ],
      "verified" : "some data here",
      "geometry" : {
         ... child elements ...
      },
      "types" : [ "type_one" ]
   },

   {
      "address_components" : [
         ... child elements ...
      ],
      "verified" : "some data here",
      "geometry" : {
         ... child elements ...
      },
      "types" : [ "type_two" ] // filter all items that match this item's value
   },
   ... more elements ...
]

Answer 1

You can use a list comprehension:

foundItems = [elem for elem in results if 'type_two' in elem['types']]

Of course you’ll probably use a variable instead of hard-coding 'type_two' like that.

This will allow other values in the types list alongside the one you are looking for. You can use if elem['types'] == ['type_two'] instead to look for that specific value only.
