Here's a concise and efficient Python code for a clock with an alarm:

python

Copy code

import datetime

import time

def set_alarm(alarm_time):

while True:

current_time = datetime.datetime.now().strftime("%H:%M:%S")

if current_time == alarm_time:

print("Alarm!")

break

time.sleep(1)

def main():

alarm_time = input("Enter the alarm time in HH:MM:SS format: ")

set_alarm(alarm_time)

if name == "__main__":

main()

Code Description

This code uses the datetime module to get the current time and compare it with the desired alarm time. It uses a while loop to continuously check the time until it matches the alarm time. The time.sleep(1) function is used to pause the execution for 1 second between each check, which helps in conserving CPU resources.

To use the code, simply run the main() function. It prompts the user to enter the alarm time in the HH:MM:SS format, and then it calls the set_alarm() function, which continuously checks the time until it matches the alarm time and prints "Alarm!".

You can customize the code further by adding additional functionality such as playing a sound or displaying a message when the alarm triggers.
