As to True/False.  There is a boolean type and its values are True and
False (note the capital letter).  But other values can be considered
True/False.  For instance 0 is considered false, and empty string is
considered false.  Any other number is considered true as is any string
that isn't empty.  Empty sequences are considered false (Tuples, lists)
