TypeError: done() takes 1 positional argument but 2 were given

Question

In my following program I basicly want to create a edit field which, after I double click it, transforms into a label with the text I wrote in the edit field. Here is my code:

GUI.py:

from tkinter import *
import sys
import Classes
root = Tk()
root.wm_title("Schelling-Cup Alpha 1.0")
root.config(background = "#FFFFFF")

#VARIABLEN LADEN

playerlist = []

#BILDER WERDEN GELADEN

hintergrund = PhotoImage(file = "C:\\Users\\Jakub Pietraszko\\Desktop\\MarioKartProject\\Hintergrund2.png")
fotobutton1 = PhotoImage(file = "C:\\Users\\Jakub Pietraszko\\Desktop\\MarioKartProject\\Button_8Spieler_.png")
fotobutton2 = PhotoImage(file = "C:\\Users\\Jakub Pietraszko\\Desktop\\MarioKartProject\\Button_16Spieler_.png")


#FIRSTFRAME EDITED
firstFrame = Frame(root, width=400, height = 400)
firstFrame.grid(row = 0, column = 0, padx = 3, pady = 3)
x = Label(firstFrame, image = hintergrund)
x.grid(row = 0, column = 0)
def callback1():
    """Die Funktion für 8 Spieler, welche dann den entsprechenden Frame lädt."""
    Classes.EditToLabel(400, 400, firstFrame)
    pass
def callback2():
    """Die Funktion für 16 Spieler, welche dann den entsprechenden Frame lädt."""
    pass
B1 = Button(firstFrame, text = "Button1", bg = "#FFFFFF", width = 700, command = callback1)
B1.config(image = fotobutton1)
B1.place(x = 290, y = 250)
B2 = Button(firstFrame, text = "Button2", bg ="#FFFFFF", width = 700, command = callback2)
B2.config(image = fotobutton2)
B2.place(x = 290, y = 450)

#SECOUNDFRAME EDITED

secoundFrame = Frame(root, width = 400, height = 400)


root.mainloop() #GUI wird upgedated. Danach keine Elemente setzen

And here is my secound file, Classes.py:

from tkinter import *
import sys

x = 100
y = 100

class EditToLabel():
    def __init__(self, x_Koordinate, y_Koordinate, whichFrame):
        self.x_Koordinate = x_Koordinate
        self.y_Koordinate = y_Koordinate
        self.whichFrame = whichFrame

        global neuesEntry
        neuesEntry = Entry(whichFrame, width = 40)
        neuesEntry.place(x = x_Koordinate, y = y_Koordinate)

        neuesEntry.bind('<Double-Button-1>', self.done)
    def done(self):
        Eintrag = neuesEntry.get()
        neuesEntry.destroy()
        neuesLabel = Label(self.whichFrame, text = Eintrag, x = self.x_Koordinate, y = self.y_Koordinate)

Now the problem is, that I get and error and dont know exactly what to do. Following error message I get now:

Exception in Tkinter callback Traceback (most recent call last):
File "C:...\Programs\Python\Python37\lib\tkinter__init__.py", line 1705, in call return self.func(*args) TypeError: done() takes 1 positional argument but 2 were given

Does anybody know what I make wrong and could give me an example how to make it better and improve it?

self.done, the bound method, doesn't take any arguments. The callback is expected to take one. — chepner
Does it need to accept an argument? I mean I dont have anything I could hand over to the menthod. What do you mean with the "callback"? — Azzlak Spieser
EXACT duplicate of attribute-error-with-event-object-and-classes — stovfl
self.done() will be called with 2 arguments, the instance reference and the event object, because it is used as callback function of bind(). — acw1668

When binding a method in Tkinter, the app sends information about the event as and argument to the function even if you dont use it.

Try:

def done(self, event = None):
    ...

Setting "event" as a default parametrer helps when you need to use self.done() through other methods besides .bind().
