What are named tuples in Python and can you give me some examples?

Named tuples are a subclass of Python's built-in tuple data type. They allow you to create tuple-like objects that have named fields, making your code more readable. For example, you can define a named tuple for a point in 2D space like this:

from collections import namedtuple
Point = namedtuple('Point', ['x', 'y'])
point = Point(10, 20)
print(point.x, point.y)  # Output: 10 20

Can you show me another example?

Sure! Here's an example of a named tuple for a car:

Car = namedtuple('Car', ['make', 'model', 'year'])
my_car = Car(make='Toyota', model='Corolla', year=2020)
print(my_car.make, my_car.model, my_car.year)  # Output: Toyota Corolla 2020

What are the benefits of using named tuples over regular tuples?

Named tuples provide better readability and self-documenting code since you can access fields by name instead of index. This reduces errors and makes your code easier to understand.

Are named tuples mutable?

No, named tuples are immutable, just like regular tuples. Once you create a named tuple, you cannot change its values.
