Use namedtuples for more readability

Posted by Afsal on 29-Jul-2022

Hello Pythonistas!

Today we will learn a simple tip that increases your code readability. That is use a namedtuple instead of a tuple/list

Let us consider the example student record with roll number, name, and age. 

Using tuple

student = (1, “Guido Van Rossum”, 50)
roll_number = student[0]
name = student[1]
age = student[2]

Using namedtuple

from collections import namedtuple

Student = namedtuple('Student', ['roll_number', 'name', 'age'])
s = Student(1, 'Guido Van Rossum', '50')


name =
roll_number = s.roll_number
age = s.age
print(f"{name=}, {roll_number=}, {age=}")

## We can access namedtuple using index also

name = s[1]
roll_number = s[0]
age = s[2]
print(f"{name=}, {roll_number=}, {age=}")

## We can make namedtuple to dictionary using _asdict method

s_dict = s._asdict()


Student(roll_number=1, name='Guido Van Rossum', age='50')
name='Guido Van Rossum', roll_number=1, age='50'
name='Guido Van Rossum', roll_number=1, age='50'
{'roll_number': 1, 'name': 'Guido Van Rossum', 'age': '50'}

Advantage of using namedtuple

If we are using list/tuple we know that elements are accessed using index.  So inorder to access the item we must know the currect index. But if we are using the namedtuple we can access element using index and a name. This makes code more readable. We can convert namedtuple object easily to dictionary using method called _asdict
