Why can't I define a variable like "miles_driven" with an underscore in Python 3.4.3 ?

You were always defining "miles_driven", it is just that the display engine
used by IDLE on OS X wasn't capable of displaying the underscore using the
combination of typeface (font), size and line height.

My guess is that you had it set to a very small size and the underscore just
wasn't visible.
