Python Dates and Times in Python (2014) Dates and Times Today and Tomorrow

datetime.time() purpose?

Docs says this:

"Return time object with same hour, minute, second, microsecond and fold. tzinfo is None. See also method timetz()."

So, I do not need to provide arguments when I run datetime.time() in the console. So it gives me datetime.time(0, 0). I expect the console to display "same" hour, minute, etc... but I don't know what "same" means :).

Now when I run (what I think is a similar) function, such as datetime.date(), I need to provide the year, month, and day as arguments.

Could someone elaborate the use of the time function?

In the datetime.time()initialization, the documentation means it returns a datetime.time object with the save values [as the arguments provided]. The default values being zero. So, datetime.time() return a midnight time of "00:00".

A datetime.time object allow comparisons of times be less than, greater than, or equal. It also allows creation of a datetime.datetime object from a datetime.date object using thecombine() method.

>>> import datetime
>>> t = datetime.time()
>>> t
datetime.time(0, 0)
>>> t1 = datetime.time(11, 20)
datetime.time(11, 20)
>>> t2 = datetime.time(13, 45)
>>> t2
datetime.time(13, 45)
>>> t1 > t2
>>> t1 < t2

>>> d = datetime.date(2019, 5, 19)
>>> d
datetime.date(2019, 5, 19)
>>> datetime.datetime.combine(d, t)
datetime.datetime(2019, 5, 19, 0, 0)

# a quick way to get a datetime object from a date object:
>>> new_dt = datetime.datetime.combined(d, datetime.time()) 
>>> new_dt
datetime.datetime(2019, 5, 19, 0, 0)
