I am trying to learn how to make a GUI so I decided to practice making a calculator. I have all of the number buttons and the '+', '-', '*', '/' buttons working. I got stuck at the decimal button. When ever I press the button in the GUI it goes into my terminal instead of the text box.
Here is the code:
from tkinter import *
root = Tk()
root.title("Calculator")
e = Entry(root, width=50, bg="light gray", fg="black", borderwidth=3)
e.grid(row=0, column=0, columnspan=4, padx=10, pady=10)
def button_equal():
second_number = e.get()
e.delete(0, END)
if math == "addition":
e.insert(0, f_num + int(second_number))
if math == "subtraction":
e.insert(0, f_num - int(second_number))
if math == "multiplication":
e.insert(0, f_num * int(second_number))
if math == "division":
e.insert(0, f_num / int(second_number))
def button_click(number):
current = e.get()
e.delete(0, END)
e.insert(0, str(current) + str(number))
def button_clear():
e.delete(0, END)
def button_add():
first_number = e.get()
global f_num
global math
math = "addition"
f_num = int(first_number)
e.delete(0, END)
deci = "."
def button_equal():
second_number = e.get()
e.delete(0, END)
if math == "addition":
e.insert(0, f_num + int(second_number))
if math == "subtraction":
e.insert(0, f_num - int(second_number))
if math == "multiplication":
e.insert(0, f_num * int(second_number))
if math == "division":
e.insert(0, f_num / int(second_number))
if math == ".":
e.insert(0, f_num, deci)
def button_subtraction():
first_number = e.get()
global f_num
global math
math = "subtraction"
f_num = int(first_number)
e.delete(0, END)
def button_multiplication():
first_number = e.get()
global math
math = "multiplication"
f_num = int(first_number)
e.delete(0, END)
def button_division():
first_number = e.get()
global f_num
global math
math = "division"
f_num = int(first_number)
e.delete(0, END)
def button_decimal():
first_number = e.get()
global f_num
global math
math = " "
f_num = int(first_number)
e.delete(0, END)
