I have been trying to make an app that have many functions associate to one buttons each. This way, if I have 70 buttons I have 70 different functions. I want to add, the respective value, when I click respective button, to a respective variable label (I am using numericproperty). As the change between this functions is only in this numeric value, I would like to make this in a more inteligent way than I did. Have anybody one suggestion of better way to do it without I have to repeat my code? Very thanks everybody, and part of my code is bellow.
.py
class SegundoScreen(Screen):
def __init__(self, **kwargs):
self.name = 'dois'
super(Screen,self).__init__(**kwargs)
def mucarela(self, *args):
screen4 = self.manager.get_screen('carrinho')
screen4.btn1 = BubbleButton(text="Muçarela", font_size='20dp', size_hint=(1,None), background_normal='1.png', background_down='2.png')
screen4.lb1 = Label(text="25,00", font_size='20dp', size_hint=(1,None))
screen4.ids.lb5.value += 25
screen4.ids.grid.add_widget(screen4.btn1)
screen4.ids.grid.add_widget(screen4.lb1)
def catupiry(self, *args):
screen4 = self.manager.get_screen('carrinho')
screen4.btn2 = BubbleButton(text="Catupiry",font_size='20dp', size_hint=(1,None), background_normal='2.png', background_down='1.png')
screen4.lb2 = Label(text="25,00",font_size='20dp', size_hint=(1,None))
screen4.ids.lb5.value += 25
screen4.ids.grid.add_widget(screen4.btn2)
screen4.ids.grid.add_widget(screen4.lb2)
def peru(self, *args):
screen4 = self.manager.get_screen('carrinho')
screen4.btn2 = BubbleButton(text="Peito de peru",font_size='20dp', size_hint=(1,None), background_normal='1.png', background_down='2.png')
screen4.lb2 = Label(text="95,00",font_size='20dp', size_hint=(1,None))
screen4.ids.lb5.value += 35
screen4.ids.grid.add_widget(screen4.btn2)

and I have more one class form that is just one label numericpropertie whose change the value when respective button has clicked. As the change is only in this label, I am locking for how can I take the price value from the text label, and flavor name from the text button. Very thanks.
for your .kv file I recommend using Classes like
<MyButton#Button>:
markup: True
font_size: '20dp'
size_hint_y: None
then in your code you could use instances of MyButton which could minify your code a little bit.

I'm trying to use this id "self.ids.input_tornillo.text" and put it inside a variable in my main.py but when running this code I got this Error: "NameError: name 'self' is not define". I think the word self just work inside a function. But I don't know if it really necessary create a funcion for this or I can do it in another way. Pls someone can give me a hand? -
main.py
class FirstWindow(Screen):
#Variables Shopping Cart
var1= StringProperty("images/shoppingcart.png")

I was thinking create a function too and make it like this

def list_items(self):
tornillo= self.ids.input_tornillo.text
tornillo1= float(tornillo) * 0.10
tornillo2= str(tornillo1)
but I don't how to call my variable "tornillo2" in my main.kv either
TextInput:

text: ""
halign: "right"

multiline: True
#size_hint: (1, .15)

#text: root.ids.input_tornillo.text*2
text: root.tornillo2
root.tornillo2 is giving me this error...
AttributeError: 'FirstWindow' object has no attribute 'tornillo2'
In the python code, define a property for the variable "tornillo2"
tornillo2 = StringProperty("")
Now you can use it in the kv file as you did it already
(text: root.tornillo2)
I need all the elements of my FirsWindow, put them in a recycleview. I'm thinking to do it from RecycleGridLayout instead of GridLayout, but I don't how to really apply it in the code. It's necesary that the GridLayout or RecycleGridLayout have cols:4, I think it's not necessary upload my py.file but I'm not sure. please I need help on this. thanks in advance.

How can I change the mouse pointer to 'hand' when hovering over a button present in a screen along with a different widget in kivy python?
I tried creating two functions in a python file. But it changes the mouse cursor for the entire page. How can I change the cursor for just the button present on the page?

I am sorry if some parts are in my language hopefully it doesn't matter
When I press the 'Add' button to add another 3 textinputs like those up the 'Add' button and I want to save the input that is put on those textinput boxes but I think I can figure that myself.
I searched but couldn't find something useful. Also this is my first time creating something in this level so sorry if it is inefficient in some ways.

I recommend using a ScrollView to contain the TextInputs. Your add() method can be:
def add(self):
# Add a new PartsTextInputs inside the ScrollView
self.ids.parts_text_inputs.add_widget(Factory.PartsTextInputs())
Then add a rule for the PartsTextInputs in the kv as well as a ScrollView to contain them. Here is what a modified kv would look like:
<PartsTextInputs#BoxLayout>: # this is a rule for building the parts TextInputs

Button:
text: "cam"
size_hint_x: None
size_hint_y: None
height: 45
width: 45
#classmethod
def button_OnPress(self):
print(self.total_area.text)
Your wrote #classmethod so you got a class method, whose first argument is not an instance of the class (usually called self) but rather the class itself (usually called cls).
Your self.total_area is therefore equivalently RootWidget.total_area which is, as the error says, an ObjectProperty.
You need to access the total_area as an attribute of an instance of your class. In this case, remove the #classmethod.
