Calculate multiple result from inputs and replace in label KIVY

Question

An app for getting width, length, and price and calculating results

In this I have 3 entries and one button that will click on that information to be calculated instead of labels

E.g :
1 –> Input1 , Input2 , Input3 all is in float
2 –> Press Button to Calculate i have multiple answers and multiple labels
How can set result in labels ?

From kivy documentation:

text

Text of the label.

Creation of a simple hello world:

widget = Label(text='Hello world')

If you want to create the widget with an unicode string, use:

widget = Label(text=u'My unicode string')

text is a StringProperty and defaults to ‘’.

If you want to change the text of a specific label, simply retrieve by using its id, and then set the desired text:

self.ids.id_of_label_you_want_to_change.text = "Text you want to set"
