What's the difference between namedtuple and dictionary in Python?

Namedtuples are immutable and provide named fields, while dictionaries are mutable and use key-value pairs.

Can you give me an example of how to use namedtuple?

Sure! Here's a simple example:

from collections import namedtuple

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

What are the advantages of using namedtuple over a dictionary?

Namedtuples provide better readability and self-documenting code, as fields can be accessed by name instead of key.

Are there any performance differences between the two?

Yes, namedtuples can be slightly faster for access due to their fixed structure, while dictionaries are more flexible.
