A namedtuple is a data structure in Python's standard library located in the collections module. It allows creating tuples with named fields, making it easy to access the fields like object attributes without using indexes. It is useful for defining lightweight data containers without manually writing classes. An example demonstrates how to use namedtuple to define a Point object with x and y fields, create an instance, and access the fields. More examples can be found at the provided link.

namedtuple is a data structure in the Python standard library, located in the collections module. It is a factory function used to create tuples with field names, allowing tuple fields to be accessed like object properties without needing to use indexes.

Using namedtuple makes it easy to define a tuple type with field names without manually writing a class. This is very useful when a lightweight data container is needed, but you still want to access the data like object properties.

Here is a simple example demonstrating how to use namedtuple:

from collections import namedtuple

# Define a namedtuple named Point with two fields: x and y
Point = namedtuple('Point', ['x', 'y'])

# Create a Point object
p1 = Point(1, 2)

# Access fields
print(p1.x)  # Output: 1
print(p1.y)  # Output: 2

In the example above, we defined a namedtuple named Point with two fields x and y. Then, we created a Point object p1 and accessed its values using field names.
