Convert list to namedtuple in python

Convert list to namedtuple in python

To convert a list to a namedtuple in Python, you can use the _make() method provided by the namedtuple class. Here's how you can do it:

First, you need to define a namedtuple with the desired field names. Then, you can use the _make() method to create a namedtuple instance from a list of values that correspond to the fields.

Here's an example:

from collections import namedtuple # Define a namedtuple with field names Person = namedtuple('Person', ['name', 'age', 'city']) # Create a list of values person_data = ['Alice', 30, 'New York'] # Convert the list to a namedtuple person = Person._make(person_data) # Now, you can access the values using named attributes print(f'Name: {person.name}') print(f'Age: {person.age}') print(f'City: {person.city}')

In this example:

  1. We define a namedtuple called Person with field names 'name', 'age', and 'city'.

  2. We create a list called person_data with values that correspond to the field names.

  3. We use the _make() method to convert the list person_data into a Person namedtuple instance.

  4. Finally, we access the values using named attributes (e.g., person.name, person.age, person.city).

This allows you to convert a list into a namedtuple, providing a more structured way to access the data within the list.
