Python Check if two list of jsons are equal

I have two list of JSON objects:

[{u'amount': 12000, u'address': u'mqdofsXHpePPGBFXuwwypAqCcXi48Xhb2f'},
 {u'amount': 1000, u'address': u'mkVuZV2kVtMzddQabFDanFi6DTwWYtgiCn'}]

[{"amount": 12000, "address": "mqdofsXHpePPGBFXuwwypAqCcXi48Xhb2f"},
 {"amount": 1000, "address": "mkVuZV2kVtMzddQabFDanFi6DTwWYtgiCn"}]

They might come in different orders, or one might be a subset of the other or just different addresses, I need a function to just say True if both include the same addresses/amounts or False if they are different.

I guess the problem is one has unicode keys/values but the other ones are strings.

I've spent too much time on this simple issue that have no clue what else to do.

so in the end this is what I wrote, might not be the most efficient way but it works!

def json_equal(json1,json2):

   number_of_items = len(json1)
   for item in json1:
       for item2 in json2:
           if item["address"] == item2["address"]:
               if item["amount"] == item2["amount"]:
                   number_of_items -= 1
                   break
           else:
               continue
   if number_of_items == 0:
       return True
   else:
       return False

The trick here is to use a data structure that ignores the order in which elements appear when performing an equality comparison - say, a set. Try this, which uses set comprehensions for extracting the addresses and amounts from each list:

{(d['address'], d['amount']) for d in lst1} == {(d['address'], d['amount']) for d in lst2}
