Hmmm...
That would give "3" since Python 2.x keeps the calculation as integer (it
won't coerce it to a float).
He could do a=int(a)/100.0 But that puts it into a floating point value,
and rounding sometimes gives surprising and unexpected results.
I am a fan of divmod. How about:
"%i.%02i" % divmod(348,100)
I dunno. Maybe its overkill.
