- Lists can easily be changed…by adding, removing, or modifying objects.…There is another data type called the tuple…which is similar to a list except for one key difference.…A tuple is immutable which means it cannot be changed.…Just like a list, a tuple contains…a sequence of objects in order…but once you've created a tuple,…you can't change anything about it.…So why would you want to use this tuple thing…which is basically just a more restrictive version…of a list?…The short answer is simplicity.…If I need to store or pass some nugget of information…that's never going to change,…then a tuple is a handy container to do that.…
For example, when I was driving to the store earlier,…I used the GPS function on my cellphone to help me navigate.…When I use the GPS to find out where I am,…it returns the answer as two values,…a latitude and a longitude.…Those two values always go together in that order…so it makes sense for the GPS function…to return them to me as a tuple.…There's no reason I would need to change…those latitude and longitude values later…
