yes hello everyone so today we will take a look to how to uh use named Tuple in Python

so some Theory button name Tuple namedtuple is a pythonic way of creating classes for the objects so we'll see in a minute how this can be done

so let's use our print hi function it's a template from the pycharm when you create a new project so I'm going to import

collections

collection start name Tuple the namedtuple is a function on the collections

in the collection package, so now you see the name Tuple I can give so let's take a look at its documentation

it says you have to provide a type name which is a string and the field names string

for example, we want to create a type person and we want to give it to

name as it's attribute h another and country

this will create our person class, for instance

now you can use this person close

theater person

what you all have to do is provide this name for example I'm giving my own name it's h which is for now string so I give it five then we provide this country Singapore

this is done so would like to see how does the person comes up when we don't want to print it

yeah you can see that person class object is created once we print it and it has all its properties so

this is the concepts from the python data model how you can create the models data models so this is a data model which holds the data and the model is the person

how you can create data models using Python's framework so this is the power of Python's framework where you say collections dot named Tuple call its function internally it creates a class on the Fly the named person and assign it following attributes when you provide the values it instantiate the object one interesting thing you can do is to try to print type

of the purse

again run it says class in the main person

thank you for now and I hope you enjoyed the video and I hope this was useful for you thank you very much
