First we need to import Two library packages 

pip install pyshorteners

pip install pyperclip

Source code:

import pyperclip
import pyshorteners
from tkinter import *

root = Tk()
root.geometry("400x200")
root.title("URL shortener")
root.configure(bg="#b48484")
url = StringVar()
url_address = StringVar()

def urlshortener():
    urladdress = url.get()
    url_short = pyshorteners.Shortener().tinyurl.short(urladdress)
    url_address.set(url_short)

def copyurl():
    url_short = url_address.get()
    pyperclip.copy(url_short)

Label(root, text = " URL Shortener", font = "poppins").pack(pady=10)
Entry(root, textvariable=url).pack(pady=5)
Button(root, text = " Generate Short URL", command = urlshortener).pack(pady=10)
Entry(root, textvariable=url_address).pack(pady=5)
Button(root, text = "Copy URL", command = copyurl).pack(pady=5)

root.mainloop()
