我是Python＆amp; Json处理。我使用的是Python 2.7。我收到几条错误消息当我执行以下代码时：
import os
import ast
import json
tweets={}
with open('C:\Python27\Test data\json\companies1.json','r') as input_file:
tweets = json.loads(input_file)
print tweets.keys()
print "\n"
错误信息如下：
Traceback (most recent call last):
File "C:/Users/afurxr3/PycharmProjects/Coudera/LargeJSON.py", line 13, in <module>
tweets = json.loads(input_file)
File "C:\Python27\lib\json\__init__.py", line 339, in loads
return _default_decoder.decode(s)
File "C:\Python27\lib\json\decoder.py", line 364, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
TypeError: expected string or buffer
Process finished with exit code 1
执行以下代码时，我没有收到任何错误，但缺少一些初始Json密钥：
import os
import ast
import json
tweets=[]
for line in open('C:\Python27\Test data\json\companies1.json','r'):
tweets.append(json.loads(line))
print (json.dumps(tweets,indent=4))
print "\n"
我的Json输入文件如下：

需要你的帮助。感谢。
答案 0 :(得分：1)
您的错误原因是json.loads需要一个字符串，然后将其解码为python对象。作为解决方案，您有两种可能的选择。
选项1
将文件对象传递给json.load：
tweets = json.load(input_file) >>> import json
>>> import pprint
>>> tweets = json.load(open('file.json'))
>>> pprint.pprint(tweets)
