Anzeigeproblem

[dennisgloeckner1776]

Moin Leute,
ich habe folgendes Problem...
Mein Programm läuft, aber die Ausgabe in der grafischen Benutzeroberfläche funktioniert nicht.
Es wird außerdem auch keine Fehlermeldung angezeigt, also ist das sehr verzwickt und ich weiß nicht weiter.
Gesucht und Ausgegeben werden sollen jeweils AV und BV(2 Auflagerkräfte, das Bild ist nicht im Internet importierbar. Ist nämlich eine eigene Skizze.
Freue mich, falls jemand das Problem kennt.

from math import *

g = Tk()

g.title("Dennis Glöckner, 013201693")
g = Canvas(highlightthickness = 0)
g.pack()

AV = ()
BV = ()

g.grid(column = 0, row = 0, columnspan = 3)

def Plot():
      q = float(E_q.get())
      LK1 = float(E_LK1.get())
      L = float(E_L.get())
      LK2 = float(E_LK2.get())
      AV = float(((((L+0.5*LK1)*(LK1*q))+(L*0.5)*(L*q)-((LK2*0.5)*(q*LK2)))/(L)))
      BV = float(((((-LK1*0.5)*(q*LK1))+((L*0.5)*(L*q))+((L+LK2*0.5)*(LK2*q)))/(L)))

bild = PhotoImage(file = "Layout2.gif")
Label(image = bild).grid(row = 0, column = 0, columnspan = 3)

Label(text = "q=").grid(row = 1, column = 0, sticky = "e")

Hi dennisgloeckner1776

Willkommen im Forum. Kannst du das folgende einmal ausprobieren:

Noch frohe Festtage.
