我对猕猴桃不熟悉，对蟒蛇不太了解。我试着运行这段代码，但它现在显示了一个错误，请帮助运行这段代码，这是我的代码

import kivy
from kivy.app import App
from kivy.uix.label import Label
from kivy.uix.anchorlayout import AnchorLayout
from kivy.uix.button import Button
from kivy.uix.widget import Widget

class MyApp (App):
    def build(self):
        MyAnchor = AnchorLayout
        bttn1 = Button (
            text = "Hello World",
            size = (100, 100),
            pos = (50,50)
        )
        MyAnchor.add_widget(bttn1)

if __name__ =='__main__':
    MyApp().run()# Here is they are complaining

这是输出：

只是几个简单的错误。你的台词：

MyAnchor = AnchorLayout

不创建MyAnchor的实例，它只是将MyAnchor设置为对AnchorLayout的引用。

而且您的build()方法不返回任何内容。

下面是您的代码的更正版本：

from kivy.app import App
from kivy.uix.anchorlayout import AnchorLayout
from kivy.uix.button import Button

class MyApp (App):
    def build(self):
        MyAnchor = AnchorLayout()  # added ()
        bttn1 = Button (
            text = "Hello World",
            size = (100, 100),
            pos = (50,50)
        )
        MyAnchor.add_widget(bttn1)
        return MyAnchor  # added return

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