How to convert a 'day/month' string to date in python and compare it with an Odoo date field?

Question

I have a day/month string, I want to convert that string to date object and compare the last day of that month to another date

Example:
For 08/2021 (august, 2021) I want to compare the last day of that month (31-08-2021) to another date (date field),

For 02/2020 I what to compare 29-02-2020 < another_date (date field)

For 02/2021 I what to compare 28-02-2020 < another_date (date field)

Answer 1

You can use calendar.monthrange to find the last day in the month if you don't want to add dateutil.

import calendar
from datetime import datetime

def get_last_day_date(year_month_str):
     date = datetime.strptime(year_month_str, "%m/%Y")
     last_day = calendar.monthrange(date.year, date.month)[1]
     return datetime(date.year, date.month, last_day)

get_last_day_date("08/2020")
# datetime.datetime(2020, 8, 31, 0, 0)
