Aprendendo Python

Depois de muito tempo inativo volto com um código de calculadora e controle de lanchonete feito em Python conforme videos do youtube - aqui

Segue o código:

from tkinter import*
import random
import time;
from tkinter import Entry

root = Tk()
root.geometry("1600x800+0+0")
root.title("Sistema de Administração de Restaurante")

text_Input = StringVar()
operator = ""

Tops = Frame(root, width = 1600, height = 50, bg = "powder blue", relief=SUNKEN)
Tops.pack(side=TOP)

f1 = Frame(root, width = 800, height = 700, relief=SUNKEN)
f1.pack(side=LEFT)

f2 = Frame(root, width = 300, height = 700, relief=SUNKEN)
f2.pack(side=RIGHT)

#====================================Time=========================================

localtime = time.asctime(time.localtime(time.time()))

#====================================Info=========================================

lblInfo = Label(Tops, font=('arial', 40, 'bold'), text = "Sistema de Administração de Restaurante", fg = "Steel Blue", bd = 10, anchor = 'w')
lblInfo.grid(row = 0, column = 0)

lblDateTime = Label(Tops, font=('arial', 25, 'bold'), text = localtime, fg = "Steel Blue", bd = 10, anchor = 'w')
lblDateTime.grid(row = 1, column = 0)
