Display the date, like "May 5th", using pythons strftime? [duplicate]

Python: Date Ordinal Output?

In Python time.strftime can produce output like "Thursday May 05" easily enough, but I would like to generate a string like "Thursday May 5th" (notice the additional "th" on the date). What is the best way to do this?

Answer 1

strftime doesn't allow you to format a date with a suffix.

Here's a way to get the correct suffix:

if 4 <= day <= 20 or 24 <= day <= 30:     suffix = "th" else:     suffix = ["st", "nd", "rd"][day % 10 - 1]

Update:

Combining a more compact solution based on Jochen's comment with gsteff's answer:

from datetime import datetime as dt  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))  print custom_strftime('%B {S}, %Y', dt.now()) 

Gives:

May 5th, 2011

Answer 2

This seems to add the appropriate suffix, and remove the ugly leading zeroes in the day number:

#!/usr/bin/python  import time  day_endings = {     1: 'st',     2: 'nd',     3: 'rd',     21: 'st',     22: 'nd',     23: 'rd',     31: 'st' }  def custom_strftime(format, t):     return time.strftime(format, t).replace('{TH}', str(t[2]) + day_endings.get(t[2], 'th'))  print custom_strftime('%B {TH}, %Y', time.localtime())
