You're calling household() and commercial() before you define E. Because you are doing a wildcard import (from tkinter import *) you're importing the constant E from tkinter, which is defined as the string "e".

The solution is:

  • don't do wildcard imports import tkinter with import tkinter as tk and then use tk. as a prefix for all tkinter objects (tk.Entry(...), tk.Button(...), etc)
  • Make sure your code runs in the correct order. If you have functions that depend on a variable, make sure those functions aren't called before the variable is defined.
