'''
Tuples are immutable,means not changable
Tuples have no append or extend method.
Elements in Tuples cannot be removed from a tuple.
You can only find elements in a tuple, since this doesn not change the tuple.
You can also use the in operator to check if an element exists in the tuple.
Tuples are faster than lists. If you have a constant set of values, use a tuple instead of a list.
It makes your code safer if you 'write-protect' data that does not need to be changed.
