title: TypeError: zip argument #2 must support iteration - Python 3
body: <p>I am trying to loop through sites on Rightmove.co.uk and print out price of listings into an excel spreadsheet. For this final step (printing to excel), i figured I might need a double 'for' loop, however i am getting a TypeError with the zip function.</p>
  
  <p>Please see my code below:</p>
  
  <pre><code>import re
  from urllib.request import urlopen as uReq
  from bs4 import BeautifulSoup as soup
  from xlwt import Workbook, Formula
  
  
  wb = Workbook()                     # Create workbook
  sheet1 = wb.add_sheet('Sheet 1')    # Create sheet, name Sheet 1 etc.
  wb.save('xlwt.example.xls')         # Save the workbook under the name
  
  postcode_list = {"5E2764","5E1682","5E757"} #   Define list of strings referring to each postcode to query
  
  
  #### Loop through the various postcodes  ####
  for url in postcode_list:
      my_url = "https://www.rightmove.co.uk/property-to-rent/find.html?searchType=RENT&amp;locationIdentifier=OUTCODE%"+ url +"&amp;insId=1&amp;radius=0.0&amp;minPrice=&amp;maxPrice=&amp;minBedrooms=&amp;maxBedrooms=&amp;displayPropertyType=&amp;maxDaysSinceAdded=&amp;sortByPriceDescending=&amp;_includeLetAgreed=on&amp;primaryDisplayPropertyType=&amp;secondaryDisplayPropertyType=&amp;oldDisplayPropertyType=&amp;oldPrimaryDisplayPropertyType=&amp;letType=&amp;letFurnishType=&amp;houseFlatShare="
      print(my_url)
  
  # Opening connection and grabbing page
  uClient = uReq(my_url)
  page_html = uClient.read()
  uClient.close()                 # Closes after reading
  
  page_soup = soup(page_html, "html.parser")
  
  containers = page_soup.findAll("span",{"class":"propertyCard-priceValue"})
  print(len(containers))      # the number of containers on one page
  
  
  for container, i in zip(containers, 25):   # loop through all containers
      price_container = container.get_text()
      sheet1.write(i,0,price_container)
      print(price_container)
      wb.save('xlwt.example.xls')
  </code></pre>
  
  <p>Any suggestions would be very much appreciated.
  Thanks,</p>
