extending a named tuple

extending_namedtuple.py

from collections import namedtuple
Bevrage = namedtuple('Bevrage',['name','color','type'])
# defining a class in which named tuple acts as a constructor or #__init__() method
class BeverageContainer(Bevrage): 
    def container_type(self):
        if self.type == 'hot':
            return "Use a Mug"
        else:
            return "A mug is not required"

# defining objects of the named tuple

coffee = BeverageContainer('coffee','light brown','hot')
soda = BeverageContainer('mountain dew','light green','cold')


print(coffee.container_type())
# Output: Use a Mug
print(soda.container_type())
# Output: A mug is not required


# for example you need the attributes for for the named tuples class we have a inbuilt private method _fields

print(Bevrage._fields)

# Output: ('name', 'color', 'type')
