Program:

Python3

from tkinter import Tk, Frame, Toplevel, Entry, Button, Text, Scrollbar, END, INSERT 
from tkinter.messagebox import showerror 
from wikipedia import summary 
  
# create function which will show summary 
def get_summary(): 
    
    # if summary will be fetch from internet 
    try: 
        
        # clear text area 
        answer.delete(1.0, END) 
          
        # show summary in text area 
        answer.insert(INSERT, summary(keyword_entry.get())) 
          
    # if any it will give error, it will be shown in a new error window 
    except Exception as error: 
        
      # Title of new error window is "Error" and message will be 
      # string given in variable error 
        showerror("Error", error) 
  
  
# create a GUI window 
root = Tk() 
  
# set title of window 
root.title("Wikipedia Summary") 
  
# set geometry of geometry 
root.geometry("770x650") 
  
# set window's width and height to  
# false => window will not be resizable 
root.resizable(False, False) 
  
# set background colour of window 
root.configure(bg="dark grey") 
  
# create a frame for entry and button 
top_frame = Frame(root, bg="dark grey") 
top_frame.pack(side="top", fill="x", padx=50, pady=10) 
  
# create a frame for text area where summary will be displayed 
bottom_frame = Frame(root, bg="dark grey") 
bottom_frame.pack(side="top", fill="x", padx=10, pady=10) 
  
# create a entry box where user can enter a keyword 
keyword_entry = Entry(top_frame, font=("Arial", 20, "bold"), width=25, bd=4) 
keyword_entry.pack(side="left", ipady=6) 
  
# create a search button 
search_button = Button(top_frame, text="SEARCH", font=( 
    "Arial", 18, "bold"), width=15, bd=4, command=get_summary) 
search_button.pack(side="right") 
  
# create a scroll bar for text area 
scroll = Scrollbar(bottom_frame) 
  
# create a text area where summary will be displayed 
answer = Text(bottom_frame, font=("Arial", 18), fg="red", 
              width=55, height=20, bd=5, yscrollcommand=scroll.set) 
answer.pack(side="left", fill="y") 
scroll.pack(side="left", fill="y") 
  
# start the GUI 
root.mainloop()
