在你的MyRoot类中，你已经定义了各种方法，但是你还没有在KV FILE中连接它们。

  1. class MyRoot(GridLayout):
  3.     def clear(self, instance):
  4.         self.masahat.text = ''
  5.         self.result_label.text = ''
  6.         self.darsad.text = ''
  8.     def standard(self, instance):
  9.         self.darsad.text = '6'
  11.     def hosein(self, instance):
  12.         self.darsad.text = '21'
  14.     # ... (similar modifications for other methods)
  16.     def calculate(self, instance):
  17.         # Your existing code for the calculate method
  19.     def __init__(self):
  20.         super(MyRoot, self).__init__()
  21.         # Your existing code
  23.         # Bind each button's on_press to its corresponding method
  24.         self.ids.clear_button.bind(on_press=self.clear)
  25.         self.ids.standard.bind(on_press=self.standard)
  26.         self.ids.hosein_momeni.bind(on_press=self.hosein)
  27.         # ... (similar bindings for other buttons)
