Lists & Tuples in Python

List and Tuple in Python:


In Python, both List and Tuple are important data structures used to store multiple values together. There are some significant differences between the two, which determine when to use a list and when to use a tuple.

What is a List?
A list in Python is an ordered, mutable collection used to store different types of data together. A list is written within square brackets `[]`.
Features: Ordered, mutable, allows duplicate items, and can contain heterogeneous data.
Common Operations: Adding items (`append`, `insert`), removing items (`remove`, `pop`), finding length (`len`), and accessing items through indexing and slicing.

What is a Tuple?
A tuple in Python is an ordered, immutable collection used to store data together. A tuple is written within parentheses `()`.
Features: Ordered, immutable, allows duplicate items, and can contain heterogeneous data.
Common Operations: Accessing items through indexing and slicing, finding length (`len`), and searching for items with the `in` operator. Although tuples are immutable, they can be "modified" by converting them to a list, making changes, and converting back to a tuple.
