Code golf! Put colons in that, with as little code as possible.

# Way too verbose.
import uuid
l=list("%012x"%uuid.getnode())
l[10:10]=l[8:8]=l[6:6]=l[4:4]=l[2:2]=':'
mac = ''.join(l)

# Shorter but not short enough
import uuid
s="%012x"%uuid.getnode()
mac = ':'.join(s[i*2:i*2+2] for i in range(6))

:)
