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. -- Steve “Cheer up,” they said, “things could be worse.” So I cheered up, and sure enough, things got worse. -- https://mail.python.org/mailman/listinfo/python-list
