import file2

win = tk.Tk()

labeltest = Label(win, text="Hello World")

win.mainloop()

file2.py [the one I want the functions in]

import file1

def testfunc():
labeltest.pack()

and I don't know why it is giving me a error please help

Answer 1

what you are trying to do is known as circular import which is not allowed in python.to solve this its either you: 1: merge the two files(but you need two program files ) 2: which i think is your solution, you call the import when need in the particular statement.

file1.py becomes

import tkinter as tk
from tkinter import *

win = tk.Tk()

labeltest = Label(win, text="Hello World")

win.mainloop()

file2 becomes:

def testfunc():
    import file1
    file1.labeltest.pack()
