python代码如何mongo

我是一个python noob(只工作了不到几个小时)。我试图读取twitter数据并将其存储在mongo数据库中，但出现以下错误：Traceback (most recent call last):

File "twit_test.py", line 8, in on_receive

db.posts.insert(data)

File "/Library/Python/2.6/site-packages/pymongo-2.0.1-py2.6-macosx-10.6-universal.egg/pymongo/collection.py", line 274, in insert

File "/Library/Python/2.6/site-packages/pymongo-2.0.1-py2.6-macosx-10.6-universal.egg/pymongo/database.py", line 249, in _fix_incoming

File "/Library/Python/2.6/site-packages/pymongo-2.0.1-py2.6-macosx-10.6-universal.egg/pymongo/son_manipulator.py", line 73, in transform_incoming

TypeError: 'str' object does not support item assignment

Traceback (most recent call last):

File "twit_test.py", line 17, in

conn.perform()

我的代码很简单：import pycurl, json

import pymongo

STREAM_URL = ".json"

USER = "XXXXXXXX"

PASS = "XXXXXXXX"

def on_tweet(data):

tweet = json.loads(data)

db.posts.insert(tweet)

from pymongo import Connection

connection = Connection()

db = connection.test

conn = pycurl.Curl()

conn.setopt(pycurl.USERPWD, "%s:%s" % (USER, PASS))

conn.setopt(pycurl.URL, STREAM_URL)

conn.setopt(pycurl.WRITEFUNCTION, on_tweet)

conn.perform()

我相信这是一个非常简单的解决办法，希望你们能帮忙。谢谢！
