I want to access 'md_bg_color' from 'tut_1.kv' and change it's value from 'tut_1.py'

I am facing problems in using kvlang with the python code because I am very new to kivy and kivymd, and I am learning kivy on my own.

I need your help and guidance in learning KIVY.

I want to access 'md_bg_color' from 'tut_1.kv' and change it's value from 'tut_1.py'.

tut_1.py

from kivymd.app import MDApp
from kivy.lang.builder import Builder
from random import randint


class tut_1(MDApp):
    def build(self):
        return Builder.load_file('/home/kali/Documents/Kivy/kivymd Tutorial/kv_lang/tut_1.kv')


tut_1().run()

tut_1.kv

MDScreen:
    id: can
    radius: [90, 90, 90, 90]
    md_bg_color: (1,0,0,.3)

THANK YOU VERY MUCH FOR GIVING YOUR VALUABLE TIME TO HELP ME.

The md_bg_color is just a property of the MDScreen. The MDScreen is the root of your MDApp because is is the return of your build() method. So, from any method of your tut_1 class, you can modify md_bg_color like this:

self.root.md_bg_color = (0,1,0,1)

If you are accessing it from outside the tut_1 class, you can use:

MDApp.get_running_app().root.md_bg_color = (0,1,0,1)
