Key Features of namedtuple
- Named Fields: Access elements by name instead of index.
- Immutability: Like tuples,
namedtuple
objects cannot be modified after creation. - Memory Efficiency: Uses less memory than a regular class or dictionary.
- Convenience: Provides useful methods like
_asdict()
and_replace()
.
How to Create a namedtuple
To create a namedtuple
, use the namedtuple
function from the collections
module. It takes two arguments:
- The name of the new type (as a string).
- A list of field names (as strings) or a single string with field names separated by spaces or commas.
from collections import namedtuple
# Define a namedtuple type
Person = namedtuple('Person', ['name'…
