How to get the last day of the month?

Question

Is there a way using Python\'s standard library to easily determine (i.e. one function call) the last day of a given month?

If the standard library doesn\'t support

Answer 1

The easiest & most reliable way I've found so Far is as:

from datetime import datetime
import calendar
days_in_month = calendar.monthrange(2020, 12)[1]
end_dt = datetime(2020, 12, days_in_month)
