SO, I have two file:

FOLDER
|_ generator.py
|_ gui.py

in generation.py there is a function that creates a random username:

import string
import random

def generate_username():
    username = "".join(random.sample(string.ascii_letters, 8))
    return username
if __name__ == '__main__':
    generate_username()

in gui.py there is a function that creates a Tkinter window with a label and a Entry:

from tkinter import * 
from generator import generate_username

def generate_window():
    top = Tk()
    label = Label(top, text="User Name")
    label.pack( side = LEFT)
    user_name = Entry(top, bd =5)
    user_name.pack(side = RIGHT)

    button_1 = Button(
    command=lambda: generate_username(),
    )
    top.mainloop()
if __name__ == '__main__':
    generate_window()

My goal is to fill the Entry in the gui.py with the username generated in generate_username function in the other script when the button is pressed (hope I expressed myself well). So basically the button has two jobs:

1. run the generate_username funtion
2. get the generated variable and write it on the Entry

I really have no idea hope to do it, I'm not even sure if it is possible. Does anyone have any idea?

CodePudding user response：

Yes it is possible. You can also use the Entry widget as an argument for your generate_username function in the other file (so that you don't need to return). Hope this helps.

from tkinter import * 
import random
import string


def generate_username(entry):
    username = "".join(random.sample(string.ascii_letters, 8))
    entry.delete(0, END)
    entry.insert(0, username)

def generate_window():
    top = Tk()
    label = Label(top, text="User Name")
    label.pack(side = LEFT)
    user_name = Entry(top, bd =5)
    user_name.pack(side ='left')

    button_1 = Button(text="Generate",
    command=lambda: generate_username(user_name),
    )
    button_1.pack(side='right')
    top.mainloop()
if __name__ == '__main__':
    generate_window()
