How To Calculate 2 Numbers Using Python And Tkinter
In This Python Tkinter Tutorial we will See How To Calculate 2 Numbers ( Sum, Mutiplication, Division, Substraction ) Using Input Text, Button And Select Option (combobox) In Python Using Tkinter and VsCode Editor.
Source Code:
import tkinter as tk
from tkinter import *
from tkinter import ttk
root = Tk()
root.title("Python Tkinter Calculate 2 Numbers")
frame = tk.Frame(root, bg='#45aaf2')
entry_n1 = tk.Entry(frame, font=('verdana',16), width=10)
entry_n2 = tk.Entry(frame, font=('verdana',16), width=10)
options = ['+','-','x','/']
selected = StringVar(frame)
selected.set(options[0])
combobox = ttk.Combobox(frame, textvariable=selected, values=options,
font=('verdana',16), width=2)
btn = tk.Button(frame, text='=',bg='grey', fg='#ffffff', font=('verdana',12), width=2)
entry_result = tk.Entry(frame, font=('verdana',16), width=10)
def calculate():
num1 = int(entry_n1.get())
num2 = int(entry_n2.get())
opr = combobox.get()
if opr == '+':
result = num1 + num2
elif opr == '-':
result = num1 - num2
elif opr == 'x':
result = num1 * num2
elif opr == '/':
result = num1 / num2
entry_result.delete(0,END)
entry_result.insert(0,result)
btn['command'] = calculate
frame.pack()
entry_n1.grid(row=0, column=0, columnspan="3", padx=5, pady=5, sticky="w")
entry_n2.grid(row=1, column=0, columnspan="3", padx=5, pady=5, sticky="w")
combobox.grid(row=2, column=0, padx=5)
btn.grid(row=2, column=1, padx=5, pady=5)
entry_result.grid(row=2, column=2, padx=5)
root.mainloop()
