KeyError python dictionary trying to set new value-CodePudding

I have a json file of players and I want to update their stats, but for some reason this raises an error

Here's my code:

players = _load('players.json') #this is a load function I use

players[user]['coins'] = 1

And here is the error:

File "main.py", line 56, in index
    players[user]['coins'] = 1
KeyError: 'player1'

I've used this method of updating stats for a while now, doesn't work for some reason

CodePudding user response：

The key error is being thrown since the players dict does not have a key in it for the variable user.

Check that user exists in players prior to doing the call:

players = {}
user = 'player1'

if user not in players:
    players[user] = {}

players[user]['coins'] = 1
