Dates for Python

A date in Python is not a data form of its own, but to work with dates as date objects, we can import a module called datetime.
First you have to install it on your computer if you dont't have just simply do "pip install datetime" then you import it.
So, in this example I will be showing you how to Import the datetime module and display the current date

       :
       import datetime
       x = datetime.datetime.now()
       print(x)

Date Output

When we execute the code from the example above the result will be

   :
   2021-01-20 14:01:32.454684

Year, month, day, hour, minute, second, and microseconds are included in the date.The datetime module has several methods for returning the date object information.

Here are a few examples, you will learn more about them later in this chapter:
Example;
Return the year and name of weekday

          :
          import datetime
          x = datetime.datetime.now()
          print(x.year)
          print(x.strftime("%A"))

Date Output

When we execute the code from the example above the result will be

 :
 2021
 Wednesday

Creating Date Objects

You can use the datetime () class constructor of the datetime module to create a date. For creating a date, the datetime() class
includes three parameters: year, month, day.
Example;
Create a date object

           :
           import datetime
           x = datetime.datetime(2021, 1, 20)
           print(x)

Date Output

When we execute the code from the example above the result will be

          :
          2021-01-20 00:00:00

The datetime() class also takes time and time zone parameters (hour, minute, second, microsecond, tzone), but they are optional and have a value of 0, by default (None for timezone).

The strftime() Method

The datetime object has a method by which date objects can be formatted into readable strings. The method is called strftime() and takes one format parameter to define the format of the string
returned.
Example;
Display the name of the month

  :

  import datetime

  x = datetime.datetime(2021, 1, 1)

  print(x.strftime("%B"))

Date Output

When we execute the code from the example above the result will be

  :

 January
