def buy_shares(self):         self.opener.addheaders = [('referer','http://example.com/stockmarket.phtml?type=buy')]         site = self.opener.open('http://www.example.com/stockmarket.phtml?type=list&full=true')          html = site.read()         soup = beautifulsoup(html)         text_list = []         stocks_list = []         in soup.findall('b'):             text_list.append(i.get_text())          start = text_list.index('change')+1         stop = text_list.index('search :')          in range(start,stop):             stocks_list.append(text_list[i])          stocks = [stocks_list[i:i+4] in range(0, len(stocks_list), 4)]         in stocks:             if i[2] == '17':                 stock_name = (i[0]).encode('utf-8')                 print stock_name                 break             else:                 stock_name = none          if stock_name != none:              print "buying"             forms1 = {"ticker_symbol" : stock_name,                      "amount_shares": "1000",                      "type" : "buy",                      "_ref_ck" : "587d56547765f577cfdaaa3a7ac8328c"                     }             data1 = urllib.urlencode(forms1)             req1 = urllib2.request('http://www.example.com/process_stockmarket.phtml?',data1)             res1 = self.opener.open(req1)             html = res1.read()             print html              if 'portfolio' in html:                 print 'sucsess'           elif stock_name == none:             print "no stock buy"          self.sell_shares()
