"AttributeError" using mainloop() function

I got an error that says: "AttributeError: 'NoneType' object has no attribute 'mainloop'"

I wrote my first GUI in python but I got an error using the mainloop function.

import tkinter as tk

root = tk.Tk().configure(bg="black")


def main():
    logo1 = tk.PhotoImage(file="C:\Logo1.png")
    logo2 = tk.PhotoImage(file="C:\Logo2.png")
    logo3 = tk.PhotoImage(file="C:\Logo3.png")

    # Creates labels
    lab1 = tk.Label(root, image=logo1).pack()
    lab2 = tk.Label(root, image=logo2).pack()
    lab3 = tk.Label(root, image=logo3).pack()

    root.mainloop()


if __name__ == "__main__":
    main()

You need to do something like this -

root = tk.Tk()
root.configure(bg="black")

And rest remains the same. The error is because the result of configure is None and NoneType has no attribute called mainloop.

The .configure() method doesn't return anything (i.e. implicitly returns None). Try this instead:

root = tk.Tk()
root.configure(bg="black")
