Python Tkinter Error Object Has No Attribute

So I am making a program similar to the arcade games. I want the lableGuess to appear in the toplevel window after clicking the frame but it gives me this error: AttributeError: 'W

Solution 1:

First at all, you should never create a new attribute out of the __init__ method.

That said, Mike pointed the trouble’s reason: you created the window object inside the new_window method, but did not called it.

You must call new_window before call guess_number – or call one inside other.

I suggest that you set window to None and call new_window inside __init__ method, then (after that) call guess_number.
