To turn an integer (0-6, or whatever) into a string, just use a tuple of
the same size:

tran = ("MONDAY", "TUESDAY", "WEDNESDAY", "THURSDAY", "FRIDAY",
"SATURDAY", "SUNDAY")
i = 1
print tran[i]

(prints "TUESDAY")

Note that I'm not sure of the actual mapping of the integers coming out
of the weekday function, so you might have to rearrange the strings above.
