Python Tkinter –AttributeError

Cannot seem to figure out the below Tkinter message. Usually doing a quick search will provide answers but this time I seem to miffed the search engines as to what might be causing the below error. Curious to know if I am missing a Python package or line 25 below is used in an older version of Python and it has been updated to a newer command.

I am importing the following packages into the script:

from tkinter import *
from tkinter import filedialog

The function is suppose to save any typed text put into a text area. It does save the file but the file is empty.

Thanks,

Kurt

Answer

The error is saying that the object returned by the asksaveasfile method doesn’t have a config method.

tkinter.filedialog.asksaveasfile(mode='w', **options)¶ Create a SaveAs dialog and return a file object opened in write-only mode.

When you call the asksaveasfile method, it automatically returns a file object in write mode already so there is no need for any further configuration to write to the file. If you were to omit the line throwing the error, your code should work the way you intended.
