Loading Message in Command Line

Question

I want to create a "animated" Loading Message for the Command Line, where the dots increment by one until there are 4 dots and the it starts from the beginning. The Problem is, that is goes up to 4 dots and then only displays them the whole time. This is my Code:

def loading(self):
    global connected
    
    x = 1
    dots = '.'
    while not connected:
        while x <= 4:
            dots = dots + '.'
            print(f"\r[-] Waiting for Incoming Connections{dots}", end='\r')
            x += 1
            time.sleep(0.2)
        dots = '.'
        x = 1
    print(connected)

This Code should be run until a "Client" connects to an open Socket on the Server.

This is another Part of my Code:

class Server(cmd.Cmd):
intro = "Welcome"
prompt = f'{bcolors.OKBLUE}$SHELL >{bcolors.ENDC} '

def __init__(self) -> None:
    super(Server, self).__init__()
    self.HOST = ''
    self.PORT = 9011
    self.SOCKET = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    self.SOCKET.bind((self.HOST, self.PORT))
    self.logger = None
    self.wait_for_connection()
    
def wait_for_connection(self):
    global connected
    loading_bar = threading.Thread(target=self.loading, args=[])
    loading_bar.start()
        
    self.SOCKET.listen(1)
    conn, addr = self.SOCKET.accept()
    self.ACTIVE_SOCKET = conn
    connected = True

So in simple Terms:

• Starting the Python Server part, then the "Loading" Should be displayed
• When Client connects, then stop the "Loading" and display Shell Prompt

At the Moment with the specified Soulution the Loading is indeed stoped, but Prompt isnt displayed correctly
