Want to print Text on the Button, and automatically write(update) the value to a txt file

[Vita]

I am very beginner in making App and kivy

Thank you for your anticipated patience in this stupid question.

This is what I tried to make. 

The user can select only one among the options, 

for examples, I select DOG and TEA and click the save button. 

Then, the result is automatically updated in previously saved file.

 How can I make this Print and save system on this code? Or any tips?

from kivy.uix.tabbedpanel import TabbedPanel, TabbedPanelItem
from kivy.lang import Builder




Builder.load_string("""
<Test>:
    do_default_tab: False
    TabbedPanelItem:
        text: 'page1'
        BoxLayout:
            BoxLayout:
                orientation:"vertical"
                Button:
                    text: 'dog'
                Button:
                    text: 'cat'
            BoxLayout:
                orientation:"vertical"
                Button:
                    text: 'tea'
                Button:
                    text: 'soda'
            Button:
                text: 'save'              


    TabbedPanelItem:
        text: 'page2'
        BoxLayout:                
            TextInput:
       
            Button:
                text: 'button'
""")




class MyApp(TabbedPanel):
    def build(self):
        return Test()


if __name__ == '__main__':
#    MyApp().run()

Choosing between dog/Cat, Tea, and Soda

Use ToggleButtons, these will ‘hold’ the selection.  Use group to make them work like radio buttons, given the user can only choose one of each category.

 

The class MyApp must be derived from App.

 

class MyApp(App):
    def build(self):
        return Test()

 

Here is a little bit to help get you started:

 

 

from kivy.app import App
from kivy.lang import Builder

kv = """
TabbedPanel:

    do_default_tab: False
    TabbedPanelItem:
        text: 'page1'
        BoxLayout:
            BoxLayout:
                orientation:"vertical"

                ToggleButton:
                    text: 'dog'
                    group: 'animal'
                ToggleButton:
                    text: 'cat'
                    group: 'animal'
            BoxLayout:
                orientation:"vertical"
                ToggleButton: 
                    text: 'tea'
                    group: 'drink'
                ToggleButton:
                    text: 'soda'
                    group: 'drink'

            Button:
                text: 'save'               


    TabbedPanelItem:
        text: 'page2'
        BoxLayout:                
            TextInput:

            Button:
                text: 'button'
"""

class MyApp(App):
    def build(self):
        return Builder.load_string(kv)


if __name__ == '__main__':
    MyApp().run()
