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()
