[Tutor] Details regarding namedtuple

[Gursimran Maken]

Hi All,

I would like to understand the use of first argument i.e. typename in
namedtuple collection.
collections.namedtuple (typename, field_names)

Example 1:
from collections import namedtuple
person = namedtuple ('person', 'age gender')
Sam = person(age=12, gender='M')
Sam.age

Example 2:
from collections import namedtuple
person = namedtuple ('xyz', 'age gender')
Sam = person(age=12, gender='M')
Sam.age
Pam = xyz(age=22, gender='F')
Pam.age

In example 1, both typename and variable name are same i.e. "person", and
we we print Sam.age we get output as 12.

In example 2, both typename and variable name are different i.e. "person"
and "xyz" respectively, and we we print Sam.age we get output as 12 but
when we type below statement we get an error, why?
Pam = xyz(age=22, gender='F')

Thanks in advance,
Gursimran.
