Question

Learning python for the first time and it’s I’m reading the JSON and decoding it correctly. I can loop through the names with the first for loop so I figured I was getting the value of names correctly. When I try to set that value to a variable I get the following error.

Traceback (most recent call last):
  File "./logger.py", line 70, in <module>
    winnerName = jsonData['players'][winner].get('name')
TypeError: list indices must be integers, not unicode

Python code:

jsonData = json.load(open('file.json'))

## Functions correctly and prints each name out.
for i in range(0,7):
  print jsonData['players'][i].get('name')

gameMatches = jsonData['games'][game]['matches']
for match in gameMatches:
  winnerBool = 1
  winner = -1
  loser = -1
  winnerName = ""
  loserName = ""
  matchCounter = 1

  ## Set the winner first then check to see who lost
  for key, value in sorted(match.iteritems(), reverse=True):
    if winnerBool:
      winner = value
  ## This is where the error keeps pointing
      winnerName = jsonData['players'][winner].get('name')
      winnerBool = 0
    elif winner != value:
      loserName = jsonData['players'][loser].get('name')
      loser = value

  print winnerName
  print loserName

JSON file:

{
   "players":[
      {"name":"Donatello","img":"\/img\/players\/1.jpg","rol":"\/img\/players\/r1.jpg"},
      {"name":"Leonardo","img":"\/img\/players\/2.jpg","rol":"\/img\/players\/r2.jpg"},

Answer 1

Use

winner = int(value)

To convert from "1" (string) to 1 (integer)

EDITED to clarify:

when you do this….

for key, value in sorted(match.iteritems(), reverse=True):
    #...

…your key and value variables will be strings. I am assuming you are iterating over this part of your JSON:

{"matches":[
     {"player1":"0","player2":"2","winner":"0"},
     {"player1":"1","player2":"3","winner":"3"},

Therefore, when you assign…

winner = value

…and try to look up…

winnerName = jsonData['players'][winner].get('name')

…you get a…

TypeError: list indices must be integers, not unicode

…because you are saying:

x = list["4"]

where it should say:

x = list[4]
