Question

i have small doubt plz clarify. In python
I know list is mutable,tuple is immutable but elements can change in list, elements can't change in tuple,why

Answer 1

list are dynamic so can add items while tuple are fixed so can't add items.

Answer 2

Tuples are more efficient for storing data that youre not gonna change, for example coordinates of specific places on a map. Lists, on the other hand, are more useful if you do actually want to change the data inside of them. Also, since tuples are immutable, they can be used as dictionary keys.
