4. Datetime
The datetime module works with dates and times. Import the classes you need:
date(year, month, day)creates a date.datetime(year, month, day, hour=0, minute=0, second=0)creates a date with a time. The time parameters are optional and default to0.- Read the parts with attributes:
.year,.month,.day,.hour,.minute,.second. strftime(format)turns a date into text. Useful codes:%Yyear with century,%mmonth01–12,%dday01–31,%H,%M,%Sfor time.timedelta(days=..., hours=..., minutes=...)is a duration. Add it to a date to move forward; subtract it to move backward.date.today()anddatetime.now()read the current date and time. They are useful in real programs, but not in these exercises: the result changes on every run, so we build fixed dates instead.
Coming from JavaScript? Python months are 1-based: date(2026, 10, 27) is October 27. In JS, new Date(2026, 9, 27) is also October because JS months are 0-based.
