Python KeyError When Trying To Access Dictionary Index 0: Dict[0]

Edit: I've moved this question to a new post: Python: KeyError when Calling Valid Key/Index in Dict I'm successfully receiving some properly formatted JSON data via websocket: whil

Solution 1:

The problem in while True: on first iteration you got a result 15800.0, but on second iteration your dictionary do not contains key = 'price'

Create a guard in while True loop, like in for loop:

while True:
    result = ws.recv()
    result = json.loads(result)
    if result and 'price' in result:
        print(result['price'])
    ...
