Get variable from another file - python -

i creating tkinter program allows user enter text nice looking box rather python shell.

as use in multiple programs made function can used in other files.

i can run in file, not import variable here code.

file 1:

import tkinter tk  def input_text(label_text, button_text):     class sampleapp(tk.tk):          def __init__(self):             tk.tk.__init__(self)             self.entry = tk.entry(self)             self.button = tk.button(self, text=button_text, command=self.on_button)             self.label = tk.label(self, text=label_text)             self.label.pack(side = 'top', pady = 5)             self.button.pack(side = 'bottom', pady = 5)             self.entry.pack()           def on_button(self):             answer = self.entry.get()             self.destroy()       w = sampleapp()     w.resizable(width=true, height=true)     w.geometry('{}x{}'.format(180, 90))     w.mainloop() 

file 2:

import text_input ti text_input import answer ti.input_text('enter text', 'ok') 

i error importerror: cannot import name 'answer'

answer local variable withinbutton. if want toimport` it, need make package attribute:

import tkinter tk  global answer  def input_text(label_text, button_text):     class sampleapp(tk.tk):     ...          def on_button(self):             global answer             answer = self.entry.get() 

however, very strange way access data. clean module design have object (sampleapp) @ hand, , extract answer method call app. more simply, why not return value on_button?

    def on_button(self):         answer = self.entry.get()         self.destroy()         return answer 

... usage be

response = my_app.on_button()
