Wikipedia Summary Generator using Python Tkinter

Prerequisite: 

• Tkinter 
• Wikipedia

Python offers multiple options for developing a GUI (Graphical User Interface). Out of all the GUI methods, Tkinter is the most commonly used method. Python with Tkinter outputs the fastest and easiest way to create GUI applications.

Wikipedia is a Python library that makes it easy to access and parse data from “wikipedia.org”. Here, we are using summary function of this module to get the summary of the argument(as a string) given to the program.

Installation

To install the Wikipedia library, just type this in terminal :

pip install wikipedia

Approach

• Import module
• Create a normal window
• Add buttons
• Create mechanism to scrap summary from wikipedia
• Display summary
• Execute code

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()
