How to write and save to text file from TextInput using kivy

I would like to get the text entered in the TextInput widget to save it to a text file. Please show me an example of how to get the values ​​entered in the TextInput widget to save it in a text file.

from kivy.app import App
from kivy.lang import Builder
from kivy.uix.screenmanager import ScreenManager, Screen
from kivy.uix.label import Label
from kivy.uix.textinput import TextInput
import os

This method was an attempt to save to a text file, but it did not work

def save(self,nam):
    fob = open('c:/test.txt','w')
    write =    fob.write(str(name))


Builder.load_string('''
<MenuScreen>:
    BoxLayout:
        Button:
            text: 'Add New Staff'
            on_press: root.manager.current = 'add_staff'
        Button:
            text: 'View Staff Profile'
        Button:
            text: 'Salary report'

<Add_new_staff>:
    nam: str(name_input)
    job: job_input
    GridLayout:
        cols: 2 
        Label:
            text: 'Name'
        TextInput:
            id: name_input
            multiline: False
        Label:
            text: 'Job'
        TextInput:
            id: job_input
        Label:
            text: 'Salary'
        TextInput:
        Label:
            text: 'Date of Joining'
        TextInput:
        Button:
            text: 'Back to menu'
            on_press: root.manager.current = 'menu'
        Button:
            text: 'Save'
            on_press: app.save(self,nam)
''')


class MenuScreen(Screen):
    pass

class Add_new_staff(Screen):
    pass

sm = ScreenManager()
sm.add_widget(MenuScreen(name='menu'))
sm.add_widget(Add_new_staff(name='add_staff'))

class TestApp(App):
    def build(self):
        return sm
