How do you define a day in python?
Python DatetimeA date in Python is not a data type of its own, but we can import a module named Show
ExampleImport the datetime module and display the current date: import datetime x = datetime.datetime.now() Try it Yourself » Date OutputWhen we execute the code from the example above the result will be: The date contains year, month, day, hour, minute, second, and microsecond. The Here are a few examples, you will learn more about them later in this chapter: ExampleReturn the year and name of weekday: import datetime x = datetime.datetime.now() print(x.year) Try it Yourself » Creating Date ObjectsTo create a date, we can use the The ExampleCreate a date object: import datetime x = datetime.datetime(2020, 5, 17) print(x) Try it Yourself » The The strftime() MethodThe The method is called
ExampleDisplay the name of the month: import datetime x = datetime.datetime(2018, 6, 1) print(x.strftime("%B")) Try it Yourself » A reference of all the legal format codes:
Python has a module named datetime to work with dates and times. Let's create a few simple programs related to date and time before we dig deeper. Example 1: Get Current Date and Time
When you run the program, the output will be something like: 2018-12-19 09:26:03.478039 Here, we have imported datetime module using One of
the classes defined in the Example 2: Get Current Date
When you run the program, the output will be something like: 2018-12-19 In this program, we have used What's inside datetime? We can use dir() function to get a list containing all attributes of a module.
When you run the program, the output will be: ['MAXYEAR', 'MINYEAR', '__builtins__', '__cached__', '__doc__', '__file__', '__loader__', '__name__', '__package__', '__spec__', '_divide_and_round', 'date', 'datetime', 'datetime_CAPI', 'time', 'timedelta', 'timezone', 'tzinfo'] Commonly used classes in the datetime module are:
datetime.date ClassYou can instantiate Example 3: Date object to represent a date
When you run the program, the output will be: 2019-04-13 If you are wondering, The variable a is a We can only import
Example 4: Get current dateYou can create a
Example 5: Get date from a timestampWe can also create
When you run the program, the output will be: Date = 2012-01-11 Example 6: Print today's year, month and dayWe can get year, month, day, day of the week etc. from the date object easily. Here's how:
datetime.timeA time object instantiated from the Example 7: Time object to represent time
When you run the program, the output will be: a = 00:00:00 b = 11:34:56 c = 11:34:56 d = 11:34:56.234566 Example 8: Print hour, minute, second and microsecondOnce you create a
When you run the example, the output will be: hour = 11 minute = 34 second = 56 microsecond = 0 Notice that we
haven't passed microsecond argument. Hence, its default value datetime.datetimeThe Example 9: Python datetime object
When you run the program, the output will be: 2018-11-28 00:00:00 2017-11-28 23:55:59.342380 The
first three arguments year, month and day in the Example 10: Print year, month, hour, minute and timestamp
When you run the program, the output will be: year = 2017 month = 11 day = 28 hour = 23 minute = 55 timestamp = 1511913359.34238 datetime.timedeltaA Example 11: Difference between two dates and times
When you run the program, the output will be: t3 = 201 days, 0:00:00 t6 = -333 days, 1:14:20 type of t3 = Notice, both t3 and t6 are of Example 12: Difference between two timedelta objects
When you run the program, the output will be: t3 = 14 days, 13:55:39 Here, we have created two
Example 13: Printing negative timedelta object
When you run the program, the output will be: t3 = -1 day, 23:59:39 t3 = 0:00:21 Example 14: Time duration in secondsYou can get the total number of seconds in a timedelta object using
When you run the program, the output will be: total seconds = 435633.233423 You can also find sum of two dates and times
using Python format datetimeThe way date and time is represented may be different in different places, organizations etc. It's more common to use Python has Python strftime() - datetime object to stringThe Example 15: Format date using strftime()
When you run the program, the output will be something like: time: 04:34:52 s1: 12/26/2018, 04:34:52 s2: 26/12/2018, 04:34:52 Here, In the above program, t, s1 and s2 are strings.
To learn more about Python strptime() - string to datetimeThe Example 16: strptime()
When you run the program, the output will be: date_string = 21 June, 2018 date_object = 2018-06-21 00:00:00 The
By the way, Visit Python strptime() to learn more. Handling timezone in PythonSuppose, you are working on a project and need to display date and time based on their timezone. Rather than trying to handle timezone yourself, we suggest you to use a third-party pytZ module.
When you run the program, the output will be something like: Local time: 2018-12-20 13:10:44.260462 America/New_York time: 2018-12-20 13:10:44.260462 Europe/London time: 2018-12-20 13:10:44.260462 Here, datetime_NY and datetime_London are datetime objects containing the current date and time of their respective timezone. How does Python show day?Use the strftime() method of a datetime module to get the day's name in English in Python. It uses some standard directives to represent a datetime in a string format. The %A directive returns the full name of the weekday. Like, Monday, Tuesday.
How do you define today in Python?How to Get the Current Date and Time in Python. Command line / terminal window access. ... . Options for datetime formating. ... . Use strftime() to display Time and Date. ... . Save and close the file. ... . To display the time in a 12-hour format, edit the file to: import time print (time.strftime("%I:%M:%S")). How do you add a day in Python?Use the timedelta() class from the datetime module to add days to a date, e.g. result_1 = date_1 + timedelta(days=3) .
How do you use days in Python?Python has a built-in datetime module that assists us in resolving a number of date-related issues. We just input the two dates with the date type and subtract them to discover the difference between the two dates, which gives us the number of days between the two dates.
