Date Ordinal Output?

Question

I\'m wondering if there is a quick and easy way to output ordinals given a number in python.

For example, given the number 1, I\'d like to output

Answer 1

Except for 1st, 2nd, and 3rd, I think they all just add th... 4th, 5th, 6th, 11th, 21st ... oh, oops ;-)

I think this might work:

def ordinal(num):
     ldig = num % 10
     l2dig = (num // 10) % 10
     if l2dig == 1:
         suffix = 'th'
     elif ldig == 1:
         suffix = 'st'
     elif ldig == 2:
         suffix = 'nd'
     elif ldig == 3:
         suffix = 'rd'
     else: 
         suffix = 'th'
     return '%d%s' % (num, suffix)
