Get Result based on the Top value

[Meeran Rizvi]

Hello guys,
Here i am creating a GUI which will act as a search engine.
When you search for a data in search box it will fetch the results from the very first page in browser and it is displayed in a Text widget
When the TOP value is 10 it should display only the first 10 results based on numbers.if it is 20 it should display first 20 results based on the number.
How should i do that?
Here is my script
<python>
from Tkinter import *
import mechanize
from bs4 import BeautifulSoup
root = Tk()

def clear_search():#Reset the search field
    Search.delete(0,END)
    Result.delete("1.0",END)

def fun(self=0):
    new = Search.get()
    url = "https://duckduckgo.com/"
    br = mechanize.Browser()
    br.set_handle_robots(False)
    br.open(url)
    br.select_form(name="x")
    br["q"] = str(new)
    res = br.submit()
    content = res.read()
    #print content
    soup = BeautifulSoup(content,"html.parser")
    mylink = soup.find_all('a')
    v = 0
    for i in mylink:
        try:
            if i.attrs['class'][0] == "result__a":
                v = v + 1
                Result.insert(END,v)
                Result.insert(END,i.text)
                Result.insert(END,'\n')
            elif i.attrs['class'][0] == "result__snippet":
                Result.insert(END,i.text)
                Result.insert(END,'\n')
                Result.insert(END,i.attrs['href'])
                Result.insert(END,'\n ')
                Result.insert(END,'--------------------------------------------------------------------------')
              
        except KeyError:
            pass
            
            
    with open("result1.xls", "w") as f:
        f.write(content)
      
Value = Label(root,text="Value:", font="-weight bold")
Value.grid(row=0,column=0,padx=15)

Search = Entry(root,width=50)
Search.grid(row=0,column=1)

Top = Label(root,text="TOP",font="-weight bold")
Top.grid(row=1,column=0)

var = StringVar(root)
var.set('10')

Dropdownlist = OptionMenu(root,var,'10','20','50','100')
Dropdownlist.grid(row=1,column=1,sticky="w")


Go = Button(root,text="GO",width=5,command=fun)
Go.bind("<Key>",fun)
Go.grid(row=1,column=1)




Reset = Button(root,text="RESET",width=5,command=clear_search)
Reset.grid(row=1,column=1,sticky="e")

Result = Text(root,height=20,width=75)
Result.grid(row=2,column=1,padx=50,pady=10)
Scroll = Scrollbar(root,command=Result.yview)
Scroll.grid(row=2,column=2,sticky=N+S)
Result.config(yscrollcommand=Scroll.set)

root.mainloop()

</python>
