python软件语言修改

我想知道如何使用Python更改Kivy语言内部标签的文本.

就像我如何将来自python的用户输入作为kivy中的标签文本.

(顺便说一句,我在实际程序中的格式是正确的,但我把它粘贴到stackoverflow)

如果我想让代码中的标签文本成为python中生成的随机数,我该如何进行呢？

from kivy.graphics import Color, Rectangle

from kivy.properties import ObjectProperty

# Create both screens. Please note the root.manager.current: this is how

# you can control the ScreenManager from kv. Each screen has by default a

# property manager that gives you the instance of the ScreenManager used.
