What are namedtuples and how are they used in data science?

Namedtuples are a subclass of tuples that allow you to access fields by name instead of index. They are useful in data science for creating lightweight, immutable data structures that can enhance code readability.

Can you give me an example of how to create a namedtuple?

Sure! You can create a namedtuple using the collections module. Here's an example:

from collections import namedtuple

# Define a namedtuple called 'Point'
Point = namedtuple('Point', ['x', 'y'])

# Create an instance of Point
p = Point(10, 20)
print(p.x, p.y)  # Output: 10 20

What are the advantages of using namedtuples over regular tuples?

Namedtuples provide better readability and self-documenting code since you can access elements by name. They also allow for more meaningful data structures, making it easier to understand the data you're working with.

Are there any performance considerations when using namedtuples?

Namedtuples are generally lightweight and have a small memory footprint compared to classes. However, if you need mutable data structures, you might want to consider other options like dictionaries.
