Creating a Date Object

Great! Now let's learn how to work with dates different from today.

Like today's date, we can create and store dates in variables. To do it, we need to create an object of class date with 3 required arguments: year, month, and day. It can be done the next way:


              12345
            
# Load class from library
from datetime import date

# Create date object
date(year = year, month = month, day = day)

Please note, that there are 3 and only 3 required arguments. Please note, that zero-padded numbers are not allowed as arguments. You can use either positional or keyword arguments. For example, we can create variable course_created and save the date this course was created into it.


              1234567
            
# Load class from library
from datetime import date

# Create date object with positional arguments
date(2021, 11, 1)
# Create date object with keyword arguments
date(day = 1, month = 11, year = 2021)

Завдання

Assign date 11th March 1998 to variable t. Remember, that you need to create an object of date class.
