Python Facebook 'NoneType object error'

I am new to programing and python. I wrote this script below and I am getting a "TypeError: 'NoneType' object is not iterable"

import csv
import json
import urllib
import sys
import time
import re

class FacebookSearch:
    def __init__(self,
        query   = '"https://graph.facebook.com/search.{mode}?{query}&{access_token}'
    ):
        access_token = 'XXXXX|XXXXX'

    def search(self, q, mode='json', **queryargs):
        queryargs['q'] = q
        query = urllib.urlencode(queryargs)


def write_csv(fname, rows, header=None, append=False, **kwargs):
    filemode = 'ab' if append else 'wb'
    with open(fname, filemode) as outf:
        out_csv = csv.writer(outf, **kwargs)
        if header:
            out_csv.writerow(header)
        out_csv.writerows(rows)

def main():
    ts = FacebookSearch()
    response, data = ts.search('appliance', result_type='recent')  #I am getting the error on this line
    js = json.loads(data)



    messages = ([msg['created_time'],  msg['id']] for msg in js.get('data', []))

    write_csv('fb_washerdryer.csv', messages, append=True)

if __name__ == '__main__':
    main()

I am not sure why I am getting the "TypeError: 'NoneType' object is not iterable" on the line where I am defining my search term for the graph API.

Add return query at the end of FacebookSearch's search method. You are actually asking it to unpack None which search is current returning. When a function has no explicitly defined return it defaults to return None.

>>> response, data = None
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'NoneType' object is not iterable
