How do I use named tuples in functions?

Named tuples are a subclass of tuples that allow you to access fields by name instead of position. You can use them in functions to improve code readability.

Can you show me an example of how to define and use a named tuple in a function?

Sure! First, you need to import namedtuple from the collections module. Then, define a named tuple like this:

from collections import namedtuple

Point = namedtuple('Point', ['x', 'y'])

You can then use it in a function:

def print_point(point):
    print(f'Point coordinates: x={point.x}, y={point.y}')

And call it like this:

p = Point(10, 20)
print_point(p)

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

Named tuples provide better readability and self-documenting code since you can access fields by name. They also allow for more meaningful code, making it easier to understand what each value represents.

Are there any limitations to using named tuples?

Yes, named tuples are immutable, meaning you cannot change their values after creation. If you need mutable objects, consider using a regular class instead.
