我从JSON文件"new.json"获取一些数据,我想过滤一些数据并将其存储到一个新的JSON文件中.这是我的代码:
import json
with open('new.json') as infile:
data = json.load(infile)
for item in data:
iden = item.get["id"]
a = item.get["a"]
b = item.get["b"]
c = item.get["c"]
if c == 'XYZ' or "XYZ" in data["text"]:
filename = 'abc.json'
try:
outfile = open(filename,'ab')
except:
outfile = open(filename,'wb')
obj_json={}
obj_json["ID"] = iden
obj_json["VAL_A"] = a
obj_json["VAL_B"] = b
我收到一个错误,追溯是:
File "rtfav.py", line 3, in <module>
data = json.load(infile)
File "/usr/lib64/python2.7/json/__init__.py", line 278, in load
**kw)
File "/usr/lib64/python2.7/json/__init__.py", line 326, in loads
return _default_decoder.decode(s) …我有一个字典列表,看起来像这样:
list = [{'id': 123, 'data': 'qwerty', 'indices': [1,10]}, {'id': 345, 'data': 'mnbvc', 'indices': [2,11]}]
等等.列表中可能有更多文档.我需要将这些转换为一个JSON文档,可以通过瓶子返回,我无法理解如何做到这一点.请帮忙.我在这个网站上看到了类似的问题,但我无法理解那里的解决方案.
我有一个大词典,可以将数据存储在推文中.这里的许多领域都有价值None或Null.当我使用get()函数时,我得到一个AttributeError: 'NoneType' object has no attribute 'get'.
我的字典很大,不可能单独处理每个案例.关于如何做到这一点的任何想法？我的代码是:
from twython import TwythonStreamer
import json
from pymongo import MongoClient
import os
from datetime import *
client = MongoClient()
db1 = client.PWSocial
db2 = client.PWSocial
db3 = client.PWSocial
db4 = client.PWSocial
APP_KEY = 'XXXXX'
APP_SECRET = 'XXXXX'
OAUTH_TOKEN = 'XXXXX'
OAUTH_TOKEN_SECRET = 'XXXXXX'
class MyStreamer(TwythonStreamer):
def on_success(self, data):
self.n=self.n+1
print self.n
print data
user=data.get("user")
tweets = db1.tweets
user_mentions = db2.user_mentions
hash_tags = db3.hash_tags
users …我正在构建一个简单的应用程序,只为用户流式传输Twitter流,并不断收到错误
File "scratch.py", line 6, in <module>
config['oauth_token'],
TypeError: 'set' object has no attribute '__getitem__'</code>
在第6行.
源代码是:
from twitter import TwitterStream
config = { --- add your 4 horsemen in this dictionary --- }
ts = TwitterStream(
auth=OAuth(
config['oauth_token'],
config['oauth_token_secret'],
config['key'],
config['secret']
)
)
openstream = ts.statuses.filter(track=words)
for item in openstream:
print item['user']['screen_name'], datetime.strptime(item['created_at'],'%a %b %d %H:%M:%S +0000 %Y'), item['text']
if datetime.now() > stop:
print datetime.now().isoformat()
break
'oauth-token'和其他变量的值当然是特定于应用程序的,我不能在这里透露它们.我是一个蟒蛇新手,并不能真正理解这里的错误,并会很高兴任何帮助.
