Tuple and List are two data structures in Python that can store data. Both data structures store data in a specific order of any type (e.g. integers or strings).
|A tuple consists of immutable objects. (Objects which cannot change after creation)||A list consists of mutable objects. (Objects which can be changed after creation)|
|Tuple has a small memory.||List has a large memory.|
|Tuple is stored in a single block of memory.||List is stored in two blocks of memory (One is fixed sized and the other is variable sized for storing data)|
|Creating a tuple is faster than creating a list.||Creating a list is slower because two memory blocks need to be accessed.|
|An element in a tuple cannot be removed or replaced.||An element in a list can be removed or replaced.|
|A tuple has data stored in () brackets. For example, (1,2,3)||A list has data stored in  brackets. For example, [1,2,3]|
A tuple should be used whenever the user is aware of what is inserted in the tuple. Suppose that a college stores the information of its students in a data structure; in order for this information to remain immutable it should be stored in a tuple.
Since lists provide users with easier accessibility, they should be used whenever similar types of objects need to be stored. For instance, if a grocery needs to store all the dairy products in one field, it should use a list.
This program stores data in a tuple and in a list; it then displays the size of both data structures.
tuple_A = ('Name = John Cleverly','Grade = Grade 2','ID = 123', 'Section = B') list_B = ['Milk','Butter', 'Dessert', 'Ice cream'] print'Tuple data is : ', tuple_A print'List data is : ', list_B print'size of a tuple is : ',tuple_A.__sizeof__() print'size of a list is : ',list_B.__sizeof__()
Despite the fact that there are more characters stored in the tuple, the list is bigger.
