Metin daha sonra değiştirilebilir bir kivy özellik, olabilir ve bir kivy özelliktir çünkü her yerde otomatik olarak güncellenen olacak. İşte .py

from kivy.app import App 
from kivy.uix.widget import Widget 
from kivy.properties import StringProperty 
import random 

class YourWidget(Widget): 
    random_number = StringProperty() 

    def __init__(self, **kwargs): 
     super(YourWidget, self).__init__(**kwargs) 
     self.random_number = str(random.randint(1, 100)) 

    def change_text(self): 
     self.random_number = str(random.randint(1, 100)) 

class YourApp(App): 
    def build(self): 
     return YourWidget() 

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

ve .kv örneği Düğmeyi tıkladığınızda

<YourWidget>: 
    BoxLayout: 
     size: root.size 
     Button: 
      id: button1 
      text: "Change text" 
      on_release: root.change_text() 
     Label: 
      id: label1 
      text: root.random_number
