1. Introduction
In Python, lists and tuples are both used to store collections of items. However, they are used in different ways and for different purposes. A list is a mutable collection, which means you can change, add, or remove items after the list is created. Think of it as a shopping list that you can update. On the other hand, a tuple is an immutable collection, meaning once it's created, it cannot be changed. It's like a barcode on a product, unchangeable once printed.
2. Key Points
1. Mutability: Lists are mutable, tuples are immutable.
2. Syntax: Lists are enclosed in square brackets [], tuples in parentheses ().
3. Performance: Tuples have a slightly faster performance compared to lists.
4. Use Case: Lists are used for more complex data collection, and tuples for fixed data structure.
3. Differences
| Characteristic | List | Tuple |
|---|---|---|
| Mutability | Mutable | Immutable |
| Syntax | Square brackets [] | Parentheses () |
| Performance | Slightly slower | Slightly faster |
| Use Case | More complex data collection | Fixed data structure |
4. Example
# Example of a List
my_list = [1, 2, 3]
my_list.append(4) # Adding an element to the list
# Example of a Tuple
my_tuple = (1, 2, 3)
# Tuples are immutable, so you cannot add or remove elements
Output:
For the List: [1, 2, 3, 4] For the Tuple: (1, 2, 3)
Explanation:
1. The list my_list was able to have an element added to it, demonstrating its mutability.
2. The tuple my_tuple remains unchanged, highlighting its immutable nature.
5. When to use?
- Use lists when you need a collection that can change over time, like a dynamic inventory of items.
- Use tuples for data that should remain constant through your program, like the days of the week or coordinates on a map.
