List and Tuple are exactly same except small differences such as List objects are mutable whereas Tuple objects are immutable. Mutable means changeable while immutable means unchangeable. In both cases insertion order is preserved, duplicate objects are allowed, heterogenous objects are allowed, index and slicing are supported.
List vs Tuple
Here are the basic differences between list and tuple data structure in Python.
| List | Tuple |
| 1. List is a Group of Comma separated Values within Square Brackets and Square Brackets are mandatory. Eg: l = [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: l[1] = 70 |
2. Tuple Objects are Immutable i.e. once we creates Tuple Object we cannot change its content. t[1] = 70 ==> 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 be used as keys for dictionaries because keys should be Hashable and Immutable. | 4. Tuple Objects can be used as Keys for Dictionaries because Keys should be Hashable and Immutable. |
