To Python this looks like:
if percent >= (60 < 70):
which looks like in your case
if 75 >= 1 # 1 => true
To get what you want you need two tests:
elif (percent >= 60) and (percent < 70):
You may not need the parens but they help to make it obvious to
both the reader and to python exactly what you want 'and'ed...
Its all to do with a thing called operator precedence which is
explained on my (now restored) web tutor in the Simple Sequences topic.
And in full detail in the Python documentation.
