Help me in solving PYCLOCK03 problem

My issue

It says to use chatgpt but I don’t have chatgpt

My code

import time
import sys

def userChoice(choice):
    if choice == "1":
        digital_clock()
    elif choice == "2":
        seconds = int(input("Enter the number of seconds to countdown: "))
        countdown_timer(seconds)
    else:
        print("Invalid choice!")

def digital_clock():
    """Displays a digital clock."""
    # Update the code below to update the time every second
    # Get the current time
    current_time = time.localtime()
    
    # Format the time as a string
    time_string = time.strftime("%Y-%m-%d %H:%M:%S", current_time)
    
    # Print the current time
    print("Current Time:", time_string)


def countdown_timer():
    """Counts down from a given number of seconds."""

if __name__ == '__main__':
    while True:
        choice = input("Choose an option (1:Digital Clock, 2:Countdown Timer): ")
        userChoice(choice)

If you google chat gpt it will show you an online open AI that you may ask questions and copy and paste code to in order to better ask your questions. Its not anything you have to download it is simply an online tool to use. I have used it to help me visualize pointers, filling a matrix, or even just needing to have a topic further broke down for me. Hope this helps!
