I want to import a script with a simple GUI into my main python script and get this error by executing test.py:

TypeError: init() missing 1 required positional argument: 'root'

Main script: test.py

import input_1

print('before window')
input_1.App()
print('after window')

GUI script: input_1.py

import tkinter as tk
import tkinter.font as tkFont
    
class App:
    def __init__(self, root):
        #setting title
        root.title("Input stator batch and number")
        #setting window size
        width=456

        ...

    def GButton_293_command(self):
        print("command")

if __name__ == "__main__":
    root = tk.Tk()
    app = App(root)
    root.mainloop()

Questions:

1. What do I do wrong? Is there something horribly wrong with my syntax?
2. How do I link the GUI-Script to my main script, when it is located in different folder?

CodePudding user response：

In your test.py script, you need to define the inputs for your App class.

Try this:

import input_1

if __name__ == "__main__":
    root = tk.Tk()
    app = input_1.App(root)
    root.mainloop()
