python get() function gives different values for class str and type str/class int and type int

I am trying to convert a python 2 code to python 3, and just came to know the difference the type() function on both versions. I am basically pulling data from a json file using pandas. I have a variable word = 0x00000010. I wanted to get the value of word from the json file.

so my code goes below

json_data = [Basically this variable have the pulled data from json file]

json_data.get(int(str(word),16), 'none') gives the value that is present in python 2, but in python 3 it is returning nan. I am assuming it has something to do with the type(str(word)) which gives class for python 3

I have seen many questions related to this difference, but nothing actually solved my question.

Json file format :

{
  "color" : "red",
  "sets" :
      {
        "0x00000010":"yellow",
        "0x00000020":"red
      }
}

and the json_data contains the dict in "sets"
