Hi all, I'm trying to do exercises from:
http://openbookproject.net/thinkcs/python/english2e/ch05.html exercise number 3 (slope function) and when I run it: python ch05.py -v the doctest for the slope function failed, because is expecting a floating point value and not an integer: Failed example: slope(2, 4, 1, 2) Expected: 2.0 Got: 2 This is the function, and how I modified so it would return a floating point value (multiply by 1.0). But this doesn't feel the right way to do things, or is it? def slope(x1, y1, x2, y2): """ >>> slope(5, 3, 4, 2) 1.0 >>> slope(1, 2, 3, 2) 0.0 >>> slope(1, 2, 3, 3) 0.5 >>> slope(2, 4, 1, 2) 2.0 """ result_slope = ((y2 - y1) / (x2 - x1)) * 1.0 return result_slope Another question is, anybody knows if these questions from this online book are answered somewhere? I can't manage to find them? Thank you for your time.
