Here i got it,using [var.get()]
When the Top value is change to 10 it displays only the first 10 results,if it
is changed to 20 it displays first 20 results.But i got a problem with my GUI
the scroll bar height is not same as my Text widget.even i used sticky its
height remains to be short only.
<python>
from Tkinter import *
import mechanize
from bs4 import BeautifulSoup
root = Tk()
options = ["10","20","30"]
var = StringVar(root)
var.set('10')
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 = 1
b = var.get()
for i in mylink:
try:
if v <= int(b):
if i.attrs['class'][0] == "result__a":
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,'--------------------------------------------------------------------')
v = v + 1
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,sticky="W")
Search = Entry(root,width=50)
Search.grid(row=0,column=1)
Top = Label(root,text="TOP",font="-weight bold")
Top.grid(row=0,column=2,sticky="W")
Go = Button(root,text="GO",width=5,command=fun)
Go.bind("<Key>",fun)
Go.grid(row=0,column=4,sticky="W")
Dropdownlist = OptionMenu(root,var,*options)
Dropdownlist.grid(row=0,column=3,padx=5,sticky="W")
Reset = Button(root,text="RESET",width=5,command=clear_search)
Reset.grid(row=0,column=5,padx=5,sticky="W")
Result = Text(root,height=20,width=69)
Result.place(x=10, y=40)
Scroll = Scrollbar(root,command=Result.yview)
Scroll.grid(row=1,column=6,sticky=N)
Result.config(yscrollcommand=Scroll.set)
root.mainloop()
</python>
