【问题描述】：
我是一名物理学家，众所周知，我们喜欢我们的鸡尾酒。因此，我正在尝试建立一个自动调酒师。不幸的是，我在 python 中编程的唯一经验就是进行物理模拟，而且我对编码并不精通。
我的问题现在是这样的：我想在 kivy 文件中使用 BartenderApp 类中有一个 python 列表，特别是在 kivy 文件中的 LoadNewIngredients 中，供微调器使用选项来自。我已经寻找了很长一段时间的解决方案，但到目前为止还没有一个有效的解决方案。我知道我应该能够使用 for 循环将微调器和标签放入 python 文件中，但我更希望它更干净一些并将它们保存在 kivy 文件中。
因此，如果有人可以帮助我如何将列表传递给 kivy 文件，将不胜感激！
这是 .py 文件：

self.buttons = []
self.ids.drinks.clear_widgets()
for btn in range(len(drink_list)):
self.buttons.append(Button(text=str(drink_list[btn]['name'])))
self.buttons[btn].bind(on_press = self.pour_drink)
self.ids.drinks.add_widget(self.buttons[btn])

#Define the ScreenManager

#Designate the .kv design file
kv = Builder.load_file('bartenderkv.kv')
class BartenderApp(App):
#I want to use the ingredients list in the kivy file
global ingredients
ingredients = []
for drink in range(len(drink_list)):
ings = list(drink_list[drink]['ingredients'].keys())
for ing in range(len(ings)):
elem = ings[ing]
if elem not in ingredients:
ingredients.append(elem)
def build(self):
return kv

BartenderApp().run()
