如何从用户读取多个文本输入

Question

I am creating an app for calculating centroid ,orthocenter, etc. So I needed to take input from the user but I'm having trouble in reading the data entered by them.

I get an error, Error says : screenmanager has no attribute text

Code:

    from kivy.lang import Builder 
    from kivymd.app import MDApp 
    from kivymd.uix.textfield import MDTextField
    from kivymd.uix.label import MDLabel 
    from kivymd.uix.button import MDIconButton
    from kivy.uix.screenmanager import Screen, ScreenManager
    from kivymd.uix.button import  MDRoundFlatButton

    # Builder 
    helper_string = """

    TriangleApp().run()

I tired printing the values in console using show(self, obj) function but it didn't work.

I added id to each MDTextField and tried calling them in show() but it showed a TypeError

I want all the 6 coordinates to be submitted at once on clicking submit button. Any help would be appreciated.

So here is a little code you can input how many inputs you want then just press Ctrl + D and it will store all the data at random. Like to be precise it will make a list name random or whatever you wanna call it.

   import sys
   random = sys.stdin.readlines()
   print(random)

Or you can refer to this site https://www.geeksforgeeks.org/taking-multiple-inputs-from-user-in-python/ it is another way to take inputs.
