# you have to assign type name and field name like class 
Dog = namedtuple('Dog','age breed name')

# now age , breed and name is a constructor of a class Dog
# its a fast method to create class

sam = Dog(age=2 , breed = 'lab' , name = 'Sammy')

sam.age

# u can get by index aswell like in tupple
sam[0] #referes to age
