我正在使用带有Kivy模块的日历应用程序。我的问题是在print_label（）函数中。看来他无法访问ID：
appointment_label = self.ids [label_id_file_content] TypeError：“ kivy.properties.DictProperty”对象不可下标
有人可以帮我吗？
谢谢

JanuaryWindow.print_label(JanuaryWindow)
这不是调用print_label的正确方法，您需要为类的特定实例而不是类本身调用方法。
例如，如果您有your_instance = JanuaryWindow()，则可以运行your_instance.print_label()。
This blog post描述了一些更通用的方法来传递引用，以访问您关心的实例。

您曾经尝试将self.ids更改为
self.root.ids['']
？
