[Month Day Suffix, Year] February 12th,2020

Description:

Many times we need to handle date in python as per requirements.

There are predefined python's string format directives. They are as follows:

Code	Meaning	Example
`%a`	Weekday as locale’s abbreviated name.	`Mon`
`%A`	Weekday as locale’s full name.	`Monday`
`%w`	Weekday as a decimal number, where 0 is Sunday and 6 is Saturday.	`1`
`%d`	Day of the month as a zero-padded decimal number.	`30`
`%-d`	Day of the month as a decimal number. (Platform specific)	`30`
`%b`	Month as locale’s abbreviated name.	`Sep`
`%B`	Month as locale’s full name.	`September`
`%m`	Month as a zero-padded decimal number.	`09`
`%-m`	Month as a decimal number. (Platform specific)	`9`
`%y`	The year without century as a zero-padded decimal number.	`13`
`%Y`	Year with century as a decimal number.	`2013`
`%H`	Hour (24-hour clock) as a zero-padded decimal number.	`07`
`%-H`	Hour (24-hour clock) as a decimal number. (Platform specific)	`7`
`%I`	Hour (12-hour clock) as a zero-padded decimal number.	`07`
`%-I`	Hour (12-hour clock) as a decimal number. (Platform specific)	`7`
`%p`	Locale’s equivalent of either AM or PM.	`AM`
`%M`	Minute as a zero-padded decimal number.	`06`
`%-M`	Minute as a decimal number. (Platform specific)	`6`
`%S`	Second as a zero-padded decimal number.	`05`
`%-S`	Second as a decimal number. (Platform specific)	`5`
`%f`	Microsecond as a decimal number, zero-padded on the left.	`000000`
`%z`	UTC offset in the form +HHMM or -HHMM (empty string if the object is naive).
`%Z`	Time zone name (empty string if the object is naive).
`%j`	Day of the year as a zero-padded decimal number.	`273`
`%-j`	Day of the year as a decimal number. (Platform specific)	`273`
`%U`	Week number of the year (Sunday as the first day of the week) as a zero-padded decimal number. All days in a new year preceding the first Sunday are considered to be in week 0.	`39`
`%W`	Week number of the year (Monday as the first day of the week) as a decimal number. All days in a new year preceding the first Monday are considered to be in week 0.	`39`
`%c`	Locale’s appropriate date and time representation.	`Mon Sep 30 07:06:05 2013`
`%x`	Locale’s appropriate date representation.	`09/30/13`
`%X`	Locale’s appropriate time representation.	`07:06:05`
`%%`	A literal '%' character.	`%`

We use the above directives to format out date in the required format.

Example as follows :





# -*- coding: utf-8 -*-

from datetime import datetime as dt

from datetime import date

def suffix(d):
     return 'th' if 11<=d<=13 else {1:'st',2:'nd',3:'rd'}.get(d%10, 'th')

def custom_strftime(format, t):
     return t.strftime(format).replace('{S}', str(t.day) + suffix(t.day))

#Your Code Here
print(custom_strftime('%B {S}, %Y', dt.now()))

In this example, we used datetime to handle dates in python. Firstly I've imported the required package. Then created a function to get the suffix for the day named as a suffix with one parameter d.

here, I added

'th' if 11<=d<=13 else {1:'st',2:'nd',3:'rd'}.get(d%10, 'th')

to get suffix for the day. {1:'st',2:'nd',3:'rd'} is type of dictionary which stoted the 'st','nd','rd' . and get is the dictionary function to get element from dictionary.

Syntax : dictionary.get(key, value)

here,

*key(Required.):

The key of the item you want to return the value from

*value(Optional.)

Value to return if the specified key does not exist.

Default value None

Example with suffix function :

1)suffix(1)

Output: 'st'

2)suffix(2)
Output: 'nd'

3)suffix(3)
Output: 'rd'

4)suffix(4)
Output: 'th'

custom_strftime(format, t) is another function to format the date .we pass date with parameter t. and format is the string format to format the date given by param t.
Here,
'{s}' is the dummy char sequence which we replace with day and suffix
as '{s}' =>> 1st

The format for formatting date is '%B {S}, %Y' Where %B prints Current Month as "February", {S} is the replacement string which is replaced with day with the suffix as 1st and %Y prints the Year of the current date.

Example:

print(custom_strftime('%B {S}, %Y', dt.now()))

Output as ==>> February 17th, 2020
