blank screen when i execute simple Kivy code

I am new to kivy and using some tutorials but i only get black screen while on the videos developers get their widget on the screen.

import kivy
from kivy.app import App
from kivy.uix.label import Label
from kivy.uix.gridlayout import GridLayout
from kivy.uix.textinput import TextInput


class MyGrid(GridLayout):
    def __int__(self, **kwargs):
        super(MyGrid, self).__int__(**kwargs)
        self.cols = 2
        self.add_widget(Label(text="Name: "))
        self.name = TextInput(multiline=False)
        self.add_widget(self.name)

        self.add_widget(Label(text="last name : "))
        self.lastName = TextInput(multiline=False)
        self.add_widget(self.lastname)

        self.add_widget(Label(text="email: "))
        self.emailName = TextInput(multiline=False)
        self.add_widget(self.emailname)


class MyApp(App):
    def build(self):
        return MyGrid()


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

You have some spelling errors in the code. The first is about the __init__ function that you spelled __int__ You also use a different variable to assign a widget and a similar one (but different) for adding it (e.g. self.lastName = TextInput(multiline=False) and self.add_widget(self.lastname))
This code should work:

from kivy.app import App
from kivy.uix.label import Label
from kivy.uix.gridlayout import GridLayout
from kivy.uix.textinput import TextInput


class MyGrid(GridLayout):
    def __init__(self, **kwargs):
        super(MyGrid, self).__init__(**kwargs)
        self.cols = 2
        self.add_widget(Label(text="Name: "))
        self.name = TextInput(multiline=False)
        self.add_widget(self.name)

        self.add_widget(Label(text="last name : "))
        self.lastName = TextInput(multiline=False)
        self.add_widget(self.lastName)

        self.add_widget(Label(text="email: "))
        self.emailName = TextInput(multiline=False)
        self.add_widget(self.emailName)


class MyApp(App):
    def build(self):
        return MyGrid()


if __name__ == '__main__':
    MyApp().run()
