datetime module python3 code example

Example 1: python set a specific datetime

from datetime import datetime

custom_date_time = datetime(2021, 7, 23, 17, 30, 29, 431717)
print(custom_date_time)

# Output:

Example 2: python run things at certain datetimes

import datetime as DT
import time

while True:
    now = DT.datetime.now()
    target = DT.datetime.combine(DT.date.today(), DT.time(hour=8))
    if target < now:
        target += DT.timedelta(days=1)

    time.sleep((target-now).total_seconds())
    # do something
