Python Data Structures
Python Data Structures
Python provides several built-in data structures that help you store and organize data efficiently. Understanding these structures is essential for effective programming in Python.
List
A list is an ordered, mutable collection that can hold elements of different types.
fruits = ["apple", "banana", "cherry"]Tuple
A tuple is like a list, but it’s immutable (cannot be changed after creation).
coordinates = (10.5, 20.4)Set
A set is an unordered collection of unique elements.
unique_numbers = {1, 2, 3, 4}Dictionary
A dictionary stores data in key-value pairs.
person = {"name": "Alice", "age": 30}String
Although primarily used for text, strings are also a sequence data structure in Python.
message = "Hello, World!"Summary Table
| Data Structure | Ordered | Mutable | Duplicates Allowed |
|---|---|---|---|
| List | Yes | Yes | Yes |
| Tuple | Yes | No | Yes |
| Set | No | Yes | No |
| Dictionary | Keys: No Values: N/A |
Yes | Keys: No Values: Yes |
| String | Yes | No | Yes |
