Just a curiosity not a real problem, I want to pass from a string like
xxaabbddee
to
xx:aa:bb:dd:ee

At the moment I have this ugly inliner
interleaved = ':'.join(orig[x:x+2] for x in range(0, len(orig), 2))

map(int, biglist)
is better than:
[int(x) for x in biglist]
at least for me.
Efficiency is pro
