Python add user specified days/months/years to today

I am trying to add x number of days or months or years to today’s date, where both x and the frequency are supplied by the user.

I have looked at dateutil.relativedelta but since it doesn’t accept a string as a parameter, where I could have perhaps tried myStr=‘months=+6’ and then used relativedelta(myStr) I’m not sure what to do. Any tips would be appreciated.

Thanks.

You can use relativedelta here, you just need to specify it correctly.

Make sure you specify today's date as a datetime object as well.

from datetime import datetime
from dateutil.relativedelta import relativedelta

def add_calander(dmy, date):
    if dmy == 'D':
        value = int(input('How many days would you like to add?'))

        date = date + relativedelta(days=value)
    if dmy == 'M':
        value = int(input('How many months would you like to add?'))

        date = date + relativedelta(months=value)
    if dmy == 'Y':
        value = int(input('How many years would you like to add?'))

        date = date + relativedelta(years=value)

    return date

today = datetime.now()
dmy = input('Do you want to add days (D), months (M) or years (Y) to todays date?')

print(add_calander(dmy, today))

This allows a user to specify the day, month or year and returns a calculated value based off the calendar year using relativedelta.

Results:

Do you want to add days (D), months (M) or years (Y) to todays date?M
