True guys, python does not have in-built operator overloading to perform manipulations on date variables, such as C or other programming languages. But, the way around for this, can be done by using in-built library datetime with timedelta and relativedelta methods for week and month respectively. Please check the code snippet below:
from datetime import datetime, date, timedelta
print(date.today() + timedelta(weeks=2))
from dateutil.relativedelta import relativedelta
This is a bit tricky but will suffice your requirement.
