# Note that in Python, everything is an object
# and it's the address of the object that is passed
# in to functions. So if you change the object in
# a function, you're also changing the original in the
# main code.
temp = thing[swapin]
thing[swapin] = thing[swapout]
thing[swapout] = temp
peeps = ["Lisa","Sharon","Graham","Chris","Sarah"]
roles = ["Boss","Brekkies","Tutor","Eve","Deep Clean"]
