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

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
