Schedule a task and render/ use the result of the task in any given time

[klllmmm]

Not sure if this is what you want

import schedule, time
from datetime import datetime

def my_task():
    custom_time = datetime(2021, 5, 1, 17, 30, 29, 431717)
    now = datetime.now()
    print(f'Custom Time:{custom_time} Current Time: {now} Time Difference: {custom_time-now}')

schedule.every(1).minutes.do(my_task)

while True:
    schedule.run_pending()
    time.sleep(1)

Output:
Custom Time:2021-05-01 17:30:29.431717 Current Time: 2021-05-04 02:06:31.249154 Time Difference: -3 days, 15:23:58.182563
Custom Time:2021-05-01 17:30:29.431717 Current Time: 2021-05-04 02:07:31.312671 Time Difference: -3 days, 15:22:58.119046

Actually, user should be able to run following code when he wants. So it should be independent of the function defined and run with while loop.

print(f'Custom Time:{custom_time} Current Time: {now} Time Difference: {custom_time-now}')
