In Python, both lists and tuples are used to store collections of items, but they have some key differences.
Lists:
– Lists are mutable, meaning you can add, remove, or modify elements after the list is created.
– They are created using square brackets ([]).
– Lists can store elements of different data types.
– Elements in a list are ordered and can be accessed using indices.
– You can use methods like `append()`, `remove()`, `sort()`, and `extend()` to modify lists in-place.
– Lists are typically used when you need a collection that can be modified.
Example:
“`python
fruits = [‘apple’, ‘banana’, ‘orange’]
“`
Tuples:
– Tuples are immutable, meaning you cannot modify their elements once the tuple is created.
– They are created using parentheses ().
– Tuples can store elements of different data types.
– Elements in a tuple are ordered and can be accessed using indices, just like in lists.
– Tuples are commonly used for grouping related pieces of data that should not be changed.
– Tuples are more memory-efficient than lists.
– Some operations, like iteration, on tuples can be faster than on lists.
Example:
“`python
point = (3, 7)
“`
To summarize, the main difference between lists and tuples is that lists are mutable, while tuples are immutable. If you need to store a collection of items that should not be changed, or if you want to ensure the integrity of the data, tuples are a good choice. On the other hand, if you need a collection that can be modified or you want to perform operations like appending or removing elements, lists are more suitable.
You can’t edit or change or modify the elements in the tuple but you can change or modify the elements in list.
