Build a Live Countdown Timer for Events in Python
A Python script that displays a real-time countdown to a target date and time, updating every second in the console.
import datetime
import time
def countdown(event_name, target_datetime):
"""Displays a live countdown to a target datetime."""
while True:
now = datetime.datetime.now()
remaining = target_datetime - now
if remaining.total_seconds() <= 0:
print(f"\n🚀 {event_name} is happening…Schedule Daily Task in Python
Use the schedule library to queue a daily task at a fixed time, then simulate a loop that checks for pending jobs.
import schedule
import time
from datetime import datetime
def daily_task():
print(f"Task executed at {datetime.now().strftime('%Y-%m-%d %H:%M:%S')}")
schedule.every().day.at("10:30").do(daily_task)
if __name__ == "__main__":
for _ in range(3):
schedule.run_pending()
time.sleep(1)Browse by section
