有没有办法在kivy中生成多个按钮？

from kivy.app import App
from kivy.uix.button import Button
from kivy.uix.gridlayout import GridLayout

class MyLayout(GridLayout):
    def __init__(self, **kwargs):
        super(MyLayout, self).__init__(**kwargs)
        self.cols = 2  # 设置布局为2列

        # 使用循环创建多个按钮
        for i in range(5):
            button = Button(text=f"Button {i+1}")
            self.add_widget(button)  # 将按钮添加到布局中

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

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