Datetime module import doubt

Question

when we write

from datetime import date

it only includes date variable from datetime variable

to import time we again type

import datetime

my question is why can't we import datetime module for both date and time?

Answer 1

from datetime import date
from datetime import time

Answer 2

the second statement
from datetime import time
doesn't work

can't we just
import datetime
module for all date & time related purposes

Answer 3

yes, you can. the difference is how you will be able to call your function in the code :
date for the former, and
datetime.date for the latter.
you can also :
import datetime as dt
then the call will be shorter:
dt.date
