Study Notes

Python Lists vs. Tuples

Lists are mutable, allowing modifications such as adding, removing, or changing elements, whereas tuples are immutable and cannot be altered after creation.
Lists are defined using square brackets [ ], while tuples are created using parentheses ( ).

Accessing Elements

Both lists and tuples support zero-based indexing, allowing access to elements by their position within the data structure.
Slicing is available in both lists and tuples, enabling the extraction of a subset of elements based on specified indices.

Performance Considerations

Tuples generally consume less memory and can be more efficient than lists, making them favorable for storing fixed collections of items.
Lists offer more built-in methods for manipulation, making them ideal for dynamic data scenarios where frequent changes occur.

Use Cases

Tuples are often used for heterogeneous (different types) collections, such as representing a record.
Lists are suitable for homogeneous (similar types) collections where the order of elements may change, such as a list of student names.
