Answer:
Here is a table comparing tuples and lists in Python:
| Feature | Tuple | List |
|---|---|---|
| Definition | Immutable sequence of elements | Mutable sequence of elements |
| Syntax | Enclosed in parentheses | Enclosed in square brackets |
| Creation | Faster creation time | Slower creation time |
| Accessing | Elements accessed by index | Elements accessed by index |
| Slicing | Supports slicing | Supports slicing |
| Modification | Cannot be modified after creation (immutable) | Can be modified after creation (mutable) |
| Size | Smaller memory footprint | Larger memory footprint |
| Use case | Used for fixed data | Used for dynamic data |
| Examples | (1, 2, 3) |
[1, 2, 3] |
In summary, tuples are immutable, ordered sequences of elements that are typically used for fixed data, while lists are mutable, ordered sequences of elements that are used for dynamic data. Tuples have faster creation time, smaller memory footprint, and are safer for use as dictionary keys, while lists are more versatile and allow for modification after creation.
