python - Alternative to using global variables in WebSockets

Question

I'm new to python and coding in general, but it seems to me like the use of global variables is generally speaking a result of bad code design, especially when it comes to speed/performance. However I can't seem to figure out a way to avoid using global variables with WebSockets. I've looked into using classes and definitions as alternatives but I haven't been able to get them to work with WebSockets.

Using the example below, without setting action_1_performed as global, print('Action 1 performed') will repeat as the WebSocket data will continuously trigger this action so long as it conforms to action_1.

Any help would be much appreciated by this novice coder!

import websockets

action_1_performed = False

def on_message(websocket, message): 
  global action_1_performed

  data = json.loads(message)[0]
  action_1 = (calculation using data)
  action_2 = (calculation using data)

  if not action_1_performed and action_1:
    action_1_performed = True
    print('Action 1')

  if action_1_performed and action_2:
    action_1_performed = False
    print('Action 2')

websocket = websocket.WebSocketApp('URL', on_message = on_message)
websocket.run_forever()
