Differences between List and Tuple

1) List is a Group of Comma separated Values within Square Brackets and Square Brackets are mandatory.

Eg: i = [10, 20, 30, 40]

1) Tuple is a Group of Comma separated Values within Parenthesis and Parenthesis are optional.

Eg: t = (10, 20, 30, 40)

t = 10, 20, 30, 40

2) List Objects are Mutable i.e. once we creates List Object we can perform any changes in that Object.

Eg: i[1] = 70

2) Tuple Objects are Immutable i.e. once we creates Tuple Object we cannot change its content.

t[1] = 70 è ValueError: tuple object does not support item assignment.

3) If the Content is not fixed and keep on changing then we should go for List.

3) If the content is fixed and never changes then we should go for Tuple.

4) List Objects can not used as Keys for Dictionaries because Keys should be Hashable and Immutable.
