how to print the text inputs from the loop in kivy

When you click button then Kivy runs it with extra argument p(widget) so you can assign function to many buttons and you will see which button was clicked.

But it means you have to get this value in function

    def p(self, widget):

Minimal working code.

If you want text only from TextInput then removed Button from return_list.

from kivy.uix.textinput import TextInput
from kivy.app import App
from kivy.uix.button import Button
from kivy.lang.builder import Builder

kv = Builder.load_string('''
ScrollView:
    GridLayout:
        id:inputs
        cols:1
        row_force_default:True
        row_default_height:30
        size_hint_y:None
        height:self.minimum_height
''')

class Accounting(App):
    
    def build(self):
        return kv

    def on_start(self):
        self.return_list = [] #print this list
        
        w = Button(text='print all the text inputs', on_press=self.p)
        self.return_list.append(w)
        self.root.ids.inputs.add_widget(w)
        
        for i in range(5):
            w = TextInput()
            self.return_list.append(w)
            self.root.ids.inputs.add_widget(w)

        return self.return_list

    def p(self, widget):
        print('widget:', widget)
        print('text  :', widget.text)
        
        for item in self.return_list:
            print(item.text)

Accounting().run()
