python: weight conversion gui with tkinter

 # Python program to create a simple GUI

# weight converter using Tkinter

from tkinter import *

# Create a GUI window

window = Tk()

# Function to convert weight

# given in kg to grams, pounds

# and ounces

def from_kg():

# convert kg to gram

# convert kg to pound

# Enters the converted weight to

# the text widget
