Simple Calculator using python Gui |Create Calculator using tkinter
Simple Calculator using python Gui – Python Me Gui Calculator Banane ke liye tkinter Python ka use hota hai. Design Simple python gui calculator ko Step by Step Wise Dekhte Hai & Python Gui Calculator Ko Create Karte Hai.
Simple Calculator using python Gui
Step 1 . Sabse Pahle Ham tkinter ko import karte hai .
import tkinter as tk
from tkinter import ttk
Step 2. Global Variable Create Karte hai.
exp = " "
Step 3. Function Create Karte Hai Entry Box ( Display ) Me Number & Arithmetic Opreater ko show karne ke liye.
def press(num): #function name press
global exp # global variable
exp=exp+str(num) # str(num) convert string
equation.set(exp) # show equation.set(exp) display expression

Step 4 . Fir Function Create Karte Hai Equal ( = Button ) Karne ke liye or Equal Karke Display karne Ke Liye
def equalpress(): # function name equalpress
try:
global exp #global variable
total = str(eval(exp)) # total karne ke liye
equation.set(total) # total num display karne ke liye
exp = " " # show expression
except:
equation.set('error') # error show karne ke liye
exp = " " # show expression
Step 5. Function create karte hai display Data Clear (Clear Button ) Karne ke liye.
def clear (): # function name clear
global exp
exp = " "
equation.set(" ")

Ab Tak Hamne Function ko create kiya Ab Ham main progromming karte hai hai.
Step 6. Main Function Se start Karte Hai
if __name__ == "__main__": # START PROGRAM
Step 7. Calculator Gui Ka size or name , icon , background color .

dk = tk.Tk() # define dk
dk.title('Calculator') # Title Name
dk.iconbitmap('Calculator.ico') # Icon
dk.geometry('258x170') # Gui Small Size
dk.maxsize(width=258,height=170) # Gui Maximum Size
dk.configure(bg='blue') # Gui backgound color

Step 8. Ab Ham Number & arithmetic operator Display karne ke liye Entry Box Create Karte hai.

equation = tk.StringVar()
dis_entry = ttk.Entry(dk,width = 40, state = 'readonly', background ='red', textvariable = equation)
dis_entry.grid(row = 0 , columnspan = 10, ipadx = 6 , ipady = 8)
dis_entry.focus()
Step 9 . Ab Ham Button Create Karke Hai 1 to 9 & 0 , +,-,/,*,Clear Button ,Equal Button ya Enter Button

btn7 = ttk.Button(dk, text = '7' , width = 5 , command = lambda : press(7) )
btn7.grid(row = 1 , column = 0 ,ipady = 4 , ipadx = 2)
btn8 = ttk.Button(dk, text = '8' , width = 5 , command = lambda : press(8) )
btn8.grid(row = 1 , column = 1 ,ipady = 4, ipadx = 2)
btn9 = ttk.Button(dk, text = '9' , width = 5 , command = lambda : press(9) )
btn9.grid(row = 1 , column = 2,ipady = 4, ipadx = 2)
btnmines = ttk.Button(dk, text = '-' , width = 8 , command = lambda : press('-') )
btnmines.grid(row = 1 , column = 3 , ipady = 3, ipadx = 2)
btnmul = ttk.Button(dk, text = '*' , width = 8 , command = lambda : press("*") )
btnmul.grid(row = 1 , column = 4 , ipady = 3, ipadx = 2)
btn4 = ttk.Button(dk, text = '4' , width = 5 , command = lambda : press(4) )
btn4.grid(row = 2 , column = 0 ,ipady = 4 , ipadx = 2)
btn5 = ttk.Button(dk, text = '5' , width = 5 , command = lambda : press(5) )
btn5.grid(row = 2 , column = 1 ,ipady = 4, ipadx = 2)
btn6 = ttk.Button(dk, text = '6' , width = 5 , command = lambda : press(6) )
btn6.grid(row = 2 , column = 2,ipady = 4, ipadx = 3)
btnplus = ttk.Button(dk, text = '+' , width = 5 , command = lambda : press("+") )
btnplus.grid(row = 2 , column = 3,ipady = 4, ipadx = 10)
btndiv = ttk.Button(dk, text = '/' , width = 5 , command = lambda : press("/") )
btndiv.grid(row = 2 , column = 4,ipady = 4, ipadx = 10)
btnequal = ttk.Button(dk, text = 'Enter' , width = 5, command = equalpress )
btnequal.grid(row = 3 , column = 4,ipady = 4, ipadx = 10)
btn0= ttk.Button(dk, text = '0' , width = 5, command = lambda : press(0) )
btn0.grid(row = 3 , column = 3,ipady = 4, ipadx = 10)
btn3 = ttk.Button(dk, text = '3' , width = 5, command = lambda : press(3) )
btn3.grid(row = 3 , column = 0 ,ipady = 4 , ipadx = 2)
btn2 = ttk.Button(dk, text = '2' , width = 5, command = lambda : press(2) )
btn2.grid(row = 3 , column = 1 ,ipady = 4, ipadx = 2)
btn1 = ttk.Button(dk, text = '1' , width = 5 , command = lambda : press(1) )
btn1.grid(row = 3 , column = 2,ipady = 4, ipadx = 2)
btnclr = ttk.Button(dk, text = 'Clear' , width = 5 , command = clear )
btnclr.grid(row = 4 , columnspan = 6,ipady = 4, ipadx = 108)
Step 10. Ab Ham Total Coding ko ek sath ek column ek add karte hai or fir aap output dekh sakte hai .

import tkinter as tk
from tkinter import ttk
exp = " "
def press(num):
global exp
exp+=str(num)
equation.set(exp)
def equalpress():
try:
global exp
total = str(eval(exp))
equation.set(total)
exp = " "
except:
equation.set('error')
exp = " "
def clear ():
global exp
exp = " "
equation.set(" ")
if __name__ == "__main__":
dk = tk.Tk()
dk.title('Calculator')
dk.iconbitmap('C:\\Users\\Admin\\PycharmProjects\\DANISH\\venv\calculator.ico')
dk.geometry('258x170')
dk.maxsize(width=258,height=170)
dk.configure(bg='blue')
# imp
equation = tk.StringVar()
dis_entry = ttk.Entry(dk,width = 40, state = 'readonly', background ='red', textvariable = equation)
dis_entry.grid(row = 0 , columnspan = 10, ipadx = 6 , ipady = 8)
dis_entry.focus()
btn7 = ttk.Button(dk, text = '7' , width = 5 , command = lambda : press(7) )
btn7.grid(row = 1 , column = 0 ,ipady = 4 , ipadx = 2)
btn8 = ttk.Button(dk, text = '8' , width = 5 , command = lambda : press(8) )
btn8.grid(row = 1 , column = 1 ,ipady = 4, ipadx = 2)
btn9 = ttk.Button(dk, text = '9' , width = 5 , command = lambda : press(9) )
btn9.grid(row = 1 , column = 2,ipady = 4, ipadx = 2)
btnmines = ttk.Button(dk, text = '-' , width = 8 , command = lambda : press('-') )
btnmines.grid(row = 1 , column = 3 , ipady = 3, ipadx = 2)
btnmul = ttk.Button(dk, text = '*' , width = 8 , command = lambda : press("*") )
btnmul.grid(row = 1 , column = 4 , ipady = 3, ipadx = 2)
btn4 = ttk.Button(dk, text = '4' , width = 5 , command = lambda : press(4) )
btn4.grid(row = 2 , column = 0 ,ipady = 4 , ipadx = 2)
btn5 = ttk.Button(dk, text = '5' , width = 5 , command = lambda : press(5) )
btn5.grid(row = 2 , column = 1 ,ipady = 4, ipadx = 2)
btn6 = ttk.Button(dk, text = '6' , width = 5 , command = lambda : press(6) )
btn6.grid(row = 2 , column = 2,ipady = 4, ipadx = 3)
btnplus = ttk.Button(dk, text = '+' , width = 5 , command = lambda : press("+") )
btnplus.grid(row = 2 , column = 3,ipady = 4, ipadx = 10)
btndiv = ttk.Button(dk, text = '/' , width = 5 , command = lambda : press("/") )
btndiv.grid(row = 2 , column = 4,ipady = 4, ipadx = 10)
btnequal = ttk.Button(dk, text = 'Enter' , width = 5, command = equalpress )
btnequal.grid(row = 3 , column = 4,ipady = 4, ipadx = 10)
btn0= ttk.Button(dk, text = '0' , width = 5, command = lambda : press(0) )
btn0.grid(row = 3 , column = 3,ipady = 4, ipadx = 10)
btn3 = ttk.Button(dk, text = '3' , width = 5, command = lambda : press(3) )
btn3.grid(row = 3 , column = 0 ,ipady = 4 , ipadx = 2)
btn2 = ttk.Button(dk, text = '2' , width = 5, command = lambda : press(2) )
btn2.grid(row = 3 , column = 1 ,ipady = 4, ipadx = 2)
btn1 = ttk.Button(dk, text = '1' , width = 5 , command = lambda : press(1) )
btn1.grid(row = 3 , column = 2,ipady = 4, ipadx = 2)
btnclr = ttk.Button(dk, text = 'Clear' , width = 5 , command = clear )
btnclr.grid(row = 4 , columnspan = 6,ipady = 4, ipadx = 108)
dk.mainloop()
