访问 kivy 文件中的 python 列表
Access python list in kivy file
我是一名物理学家，众所周知，我们喜欢我们的鸡尾酒。因此，我正在尝试构建一个自动调酒师。不幸的是，我在 python 编程的唯一经验是进行物理模拟，而且我对编码并不那么精通。
我的问题现在是这样的：class BartenderApp 中有一个 python 列表，我想在 kivy 文件中使用它，特别是在kivy 文件中的 LoadNewIngredients，供微调器从中选择。我已经寻找了很长一段时间的解决方案，none 到目前为止已经奏效了。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！

尝试向您的应用添加一个 ListProperty (https://kivy.org/doc/stable/api-kivy.properties.html) class。像这样：
class BartenderApp(App):
ingredients = ListProperty()
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 self.ingredients:
self.ingredients.append(elem)
列表 属性 可在 Python 和 KV 文件中访问。更重要的是，它们可以绑定到回调，以便您可以创建自己的事件！
您现在可以在 KV 文件中引用 app.ingredients 并且当 app.ingredients 更改时，列表定义的任何对象都会自动更新。例如，如果您的 KV 文件中有以下标签：
Label:
text: app.ingredients[0]
当您更改列表时，文本会自动更新。不过要小心，如果您引用的索引中没有对象，您可能会遇到索引错误。
请告诉我您的进展情况以及它是否解决了您的问题。
我终于设法解决了它，也许不是最好的解决方案，但它有效。
在 class LoadNewIngredients 中，我编写了一个函数来检查可用的成分和 returns 包含成分的列表。然后使用 root.function_name().
在 kivy 应用程序中引用此函数

当您更改列表时，文本会自动更新。不过要小心，如果您引用的索引中没有对象，您可能会遇到索引错误。
请告诉我您的进展情况以及它是否解决了您的问题。
我终于设法解决了它，也许不是最好的解决方案，但它有效。
在 class LoadNewIngredients 中，我编写了一个函数来检查可用的成分和 returns 包含成分的列表。然后使用 root.function_name().
在 kivy 应用程序中引用此函数.py 文件：
#Everything needed for kivy
from kivy.app import App
from kivy.uix.widget import Widget
from kivy.lang import Builder
from kivy.uix.screenmanager import ScreenManager, Screen
from kivy.core.window import Window
from kivy.uix.button import Button
from kivy.clock import mainthread
from functools import partial
#Import drink list
from drinks import drink_list, drink_options
class drink:
def __init__(self,name,ingredients,amount):
self.name = name
self.ingredients = ingredients
self.amount = amount
#Define the different screens
class MainMenu(Screen):
pass
class UseLastIngredients(Screen):
pass
class DrinkMenu(Screen):
#Mainthread will pause shortly to give script time, the rest adds the buttons
@mainthread
def on_enter(self):
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])
def pour_drink(self, button):
print(button.text)
class LoadNewIngredients(Screen):
def spinner_clicked(self, ident, value):
if ident == 1:
pass
if ident == 2:
pass
if ident == 3:
pass
if ident == 4:
pass
if ident == 5:
pass
if ident == 6:
pass
if ident == 7:
pass
if ident == 8:
pass
#I want to use the ingredients list in the kivy file
def get_ingredients(self,*args,**kwargs):
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)
return ingredients
#Define the ScreenManager
class MenuManager(ScreenManager):
pass
#Designate the .kv design file
kv = Builder.load_file('bartenderkv.kv')
class BartenderApp(App):
def build(self):
return kv
if __name__ == '__main__':
BartenderApp().run()
这里是 .kv 文件：

#on all the different menu windows
