Scientific calculator with python

This is my scientific calculator.
Can we do a written code wdc??
from tkinter import*
import math
import parser
import tkinter.messagebox

root = Tk()
root.title(“Scientific Calculator”)
root.configure(bg=“black”)
root.resizable(width=False, height=False)
root.geometry(“480x568+0+0”)

calc = Frame(root)
calc.grid()
