operator = opt_entry.get()

if operator == '+':
add = int(num1) + int(num2)
tk.messagebox.showinfo('Addition',add)
elif operator == '-':
sub = int(num1) - int(num2)
tk.messagebox.showinfo('Subtraction',sub)
print("The sub value is ", sub)
elif operator == '/':
div = int(num1) / int(num2)
tk.messagebox.showinfo('Division',div)

mul = int(num1) * int(num2)
tk.messagebox.showinfo('Multiply',mul)
else:
tk.messagebox.showinfo('Alert','Wrong Operator')

#header label
header_label = tk.Label(root,text="Welcome to Calculator")
canvas1.create_window(165,35,window=header_label)

#num1 input field
num1_entry = tk.Entry(root,text='Num1')
canvas1.create_window(215,75,window=num1_entry)
num1_label = tk.Label(root,text='Enter Num1 Value :')
canvas1.create_window(95,75,window=num1_label)

#num2 input field
num2_entry = tk.Entry(root,text='Num2')
canvas1.create_window(215,105,window=num2_entry)
num2_label = tk.Label(root,text='Enter Num2 Value :')
