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

Your code is easily converted to a comprehension form:

':'.join(h[i:i+2] for i in range(0,12,2))
