How to remove an OSC message from a list?

Question

I have the following patch on Pure Data. When I click on the green button, I connect to the network and send these messages in OSC format to a list. When I click the red button, I disconnect from the network, but the OSC messages remain on the list. How do I remove them too?

This is my Python code responsible for activating the server and putting messages on the list.

# Module that creates user-friendly and uncomplicated command line applications 
import argparse
# Pythonosc library module that does not require the sender and receiver of the message to be directly connected 
from pythonosc import dispatcher
# Pythonosc library module that imports a server capable of receiving messages in OSC format 
from pythonosc import osc_server
from pythonosc.osc_server import BlockingOSCUDPServer

# Creating variable list to receive "hello" messages
hello = []
# Creating variable list to receive "input" messages
entrada = []
# Creating variable list to receive "output" messages
saida = []
    
# Function that attach each message to the variable 
def getHello(address:str):
    # Append message
    hello.append(address)
    # Print hello variable
    #print (hello)
    
# Function that attach each message to the variable 
def getEntrada(address:str):
    # Append message
    entrada.append(address)
    # Print hello variable
    #print (hello)
    
# Function that attach each message to the variable 
def getSaida(address:str):
    # Append message - Adiciona elemento no final da lista
    saida.append(address)
    # Print hello variable
    #print (hello)

  parser.add_argument("--port",
  # arbitrarily chosen number. It can be any free port on the computer.
      type=int, default=60000, help="The port to listen on")   
  # Analyzes the data entered and prints it on the screen, if they are valid    
  args = parser.parse_args()  
  # Dispatcher maps OSC addresses to functions and calls the functions with the messages’ arguments.
  dispatcher = dispatcher.Dispatcher() 
  # Dispatcher associates addresses with functions by storing them in a mapping
  # An address can contains wildcards as defined in the OSC specifications
  # Call the Dispatcher.map method with an address pattern and a     handler callback function
  """ print Pure Data messages on terminal
  """
  # Map the OSC messages to this function and call the functions that put them in lists  
  dispatcher.map("/hello/*", getHello)
  dispatcher.map("/input/*", getEntrada)
  dispatcher.map("/output/*", getSaida)
  
  server = osc_server.ThreadingOSCUDPServer((args.ip, args.port), dispatcher) # Reading IP, port and received message  
  while True: # Starting server loop
      try:
            print("Serving on {}".format(server.server_address)) # While server is active, receive messages
            server.serve_forever()
      except KeyboardInterrupt: # When interrupt key is triggered, end loop 
          #print(messages)
          break    # Ends loop
print("\n")
print(hello) # Print message and terminate script execution
print(entrada)
print(saida)

print("\n")
