tkinter 'NoneType' object has no attribute 'config'

August 18, 2022

I got an error for AttributeError: ‘NoneType’ object has no attribute ‘config’ when I run a Treasure Island game I created (very original). I’ve looked at other posts about this and tried the same thing to no solution, anyway, here’s the code:

import tkinter
window = tkinter.Tk()

window.title("Treasure Island")
window.geometry("500x500")

text = tkinter.Label(window, text='''
          |                   |                  |                     |

text.pack()
text = text.config(font=('length',15))

line1 = tkinter.Label(window, text="Welcome to Treasure Island,\n"
                                   "Your goal is to find the buried Treasure!")

line1.pack()
line1 = text.config(font=('length',15))

window.mainloop()

Exact error:

    line1 = text.config(font=('length',15))
AttributeError: 'NoneType' object has no attribute 'config'

>Solution :

You should check this from tkinter documents, but I suppose that tkinter.Label().config() -method does not return anything (or put it another words, it returns None).

text.pack()

## Here you set text as return value from config method
# text = text.config(font=('length',15))
## Try this intestad
text.config(font=('length',15))

line1 = tkinter.Label(window, text="Welcome to Treasure Island,\n"
                                  "Your goal is to find the buried Treasure!")

line1.pack()

## Here you try to re-use the value which is None
#line1 = text.config(font=('length',15))
## Try this instead

line1.config(font=('length',15))

window.mainloop()
