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

Here's a function I wrote as part of a calendar type of program I wrote (I'm not including the whole program). It adds on the correct ordinal for any number greater than 0. I included a loop to demo the output.

def ordinals(num):
    # st, nums ending in '1' except '11'
    if num[-1] == '1' and num[-2:] != '11':
        return num + 'st'
    # nd, nums ending in '2' except '12'
    elif num[-1] == '2' and num[-2:] != '12':
        return num + 'nd'
    # rd, nums ending in '3' except '13'
    elif num[-1] == '3' and num[-2:] != '13':
        return num + 'rd'
    # th, all other nums
    else:
        return num + 'th'

data = ''

# print the first 366 ordinals (for leap year)
for i in range(1, 367):
    data += ordinals(str(i)) + '\n'

# print results to file
with open('ordinals.txt', 'w') as wf:
   wf.write(data)
