---------------------------------------------------

from datetime import date


def after_month(given_date, month):

    yyyy = int(((given_date.year * 12 + given_date.month) + month)/12)

    mm = int(((given_date.year * 12 + given_date.month) + month)%12)


    if mm == 0:

        yyyy -= 1

        mm = 12

    return given_date.replace(year=yyyy, month=mm)


 print(next_date, end = ' ')

링크에서 처럼 현재를 입력하고 한달후를 출력하고 싶으면 위코드에 무엇을 추가하고 수정해줘야 할까요?
