How do you extract only the date from a python datetime?

You can use date and time methods of the datetime class to do so:

>>> from datetime import datetime
>>> d = datetime.now()
>>> only_date, only_time = d.date(), d.time()
>>> only_date
datetime.date(2015, 11, 20)
>>> only_time
datetime.time(20, 39, 13, 105773)

Here is the datetime documentation.

Applied to your example, it can give something like this:

>>> milestone["only_date"] = [d.date() for d in milestone["datetime"]]
>>> milestone["only_time"] = [d.time() for d in milestone["datetime"]]

How to remove time portion of date in C# in DateTime object only?

Use the Date property:

var dateAndTime = DateTime.Now;
var date = dateAndTime.Date;

The date variable will contain the date, the time part will be 00:00:00.

Extract time from datetime and determine if time (not date) falls within range?

This line:

str_time = datetime.strptime(Datetime, "%m/%j/%y %H:%M")

returns a datetime object as per the docs.

You can test this yourself by running the following command interactively in the interpreter:

>>> import datetime
>>> datetime.datetime.strptime('12/31/13 00:12', "%m/%j/%y %H:%M")
datetime.datetime(2013, 1, 31, 0, 12)
>>>

The time portion of the returned datetime can then be accessed using the .time() method.

>>> datetime.datetime.strptime('12/31/13 00:12', "%m/%j/%y %H:%M").time()
datetime.time(0, 12)
>>>

The datetime.time() result can then be used in your time comparisons.

Python datetime get only days from datetime object

This is a nice example for date comparison.

import datetime

str_date = "2019-03-18"

print(datetime.datetime.today().date())

object_date = datetime.datetime.strptime(str_date, '%Y-%m-%d')
if datetime.datetime.today().date() >= object_date.date():
    print(True)
else:
    print(False)

print((object_date.date() - datetime.datetime.today().date()).days)

Getting only time of a datetime object

You can use the ToString method with the appropriate formatting string:

var time = date.ToString("H:mm");
