Kivy programming error

I am new to kivy...

I got some errors in just a hello world program and I am not able to understand it.

Please help me out

The code is

from kivy.app import App

from kivy.uix.label import Label

class test(App):
        def build(self):
                return Label(text="hello world")

if __name__=="__main__":
    test().run()

The error message is

Have you imported kivy to begin with?

import kivy
from kivy.app import App
from kivy.uix.floatlayout import FloatLayout

Your first error is "Ignored (import error)".
You need to install the "python3-pygame".
However, the official repository of Ubuntu does not have "python3-pygame".
For example, please install to do this.

sudo add-apt-repository ppa:thopiekar/pygame
sudo aptitude update
sudo aptitude install python3-pygame
