Simple evaluator X21787
Write a function @evaluator(op, p, q)@ to compute simple boolean
expressions. The function receives as arguments a string @op@ that is
always either ’and’,
’or’ or ’not_or’,
and two booleans
and
.
The function has to return either the value of the
and expression @p and q@, the value of the
or expression @p or q@ or the value of the
not_or expression @not (p or q)@ depending on
the actual value of @op@. Hint: Use the python
boolean operators @and@, @or@ and @not@ to define the function.
