Python last index (not per number)

I'm trying to read the TradesHistory from krakenn but it doesn't work with the index. It only works if I enter the right trade. How can I step through each individual trade individually?

With the following command I get all the trades. It works.

print(resp.json()['result']['trades'])

If I wanted to access the first index now, it doesn't work.

print(resp.json()['result']['trades'][0]['ordertxid'])

Only after entering the correct trade id can I access the following index.

print(resp.json()['result']['trades']['12345-abcde-ZYXWE']['ordertxid'])

What am I doing wrong? How can I access the correct index without first knowing the ID?

{
   "error":[
      
   ],
   "result":{
      "count":2,
      "trades":{
         "12345-abcde-ZYXWE":{},
         "ZYXWE-12345-abcde":{
            "ordertxid":"xyz",
         }
      }
   }
}

various Python index commands with different JSON formats

In order to go over all the trades, you can loop over the trades that were made and extract their information.

You can use a for loop like this:

trades = resp.json()['result']['trades']
for trade in trades: # accessing each trades
    if trades[trade] == {}:
        print('trade {} is empty.'.format(trade))
        continue
    print('{}\'s trade information:'.format(trade))
    for value in trades[trade]: # accessing each value inside the trade dictionary
        print(value, ':', trades[trade][value])
