Using tkinter to input into a variable, to be called : <p>I'm currently working on a scraper-sort of program, which will enter a Wikipedia page, and in its current form, will scrape the references from the page.</p>

<p>I'd like to have a gui that will allow the user to input a Wikipedia page. I want the input to be attached to the <code>selectWikiPage</code> variable, but have had no luck as of far.</p>

<p>Below is my current code.</p>

<pre><code>import requests
from bs4 import BeautifulSoup
import re
from tkinter import *

#begin tkinter gui
def show_entry_fields():
   print("Wikipedia URL: %s" % (e1.get()))
   e1.delete(0,END)
master = Tk()
Label(master, text="Wikipedia URL").grid(row=0)
e1 = Entry(master)
e1.insert(10,"http://en.wikipedia.org/wiki/randomness")
e1.grid(row=0, column=1)
Button(master, text='Scrape', command=master.quit).grid(row=3, column=0, sticky=W, pady=4)
mainloop( )

session = requests.Session()
selectWikiPage = input(print("Please enter the Wikipedia page you wish to scrape from"))
if "wikipedia" in selectWikiPage:
    html = session.post(selectWikiPage)
    bsObj = BeautifulSoup(html.text, "html.parser")

    findReferences = bsObj.find('ol', {'class': 'references'}) #isolate refereces section of page
    href = BeautifulSoup(str(findReferences), "html.parser")
    links = [a["href"] for a in href.find_all("a", href=True)]

    for link in links:
        print("Link: " + link)

else:
    print("Error: Please enter a valid Wikipedia URL")
</code></pre>

<p>Many thanks in advance.</p>
