Elegant Format for a MAC Address in Python 3.2

Question

I am looking for a more elegant solution to formatting a MAC address with colons. I am using Python 3.2. A fancy list comprehension perhaps?

s=\"\"
h=\"0023         


        

Answer 1

Not sure how pretty this is, but it will do what you ask:

':'.join([h[i:i+2] for i,j in enumerate(h) if not (i%2)])

gives:

'00:23:3a:99:0c:21'
