'dict' object has no attribute 'read'
提问by Galen
What is wrong with my code?
我的代码有什么问题？
>>> import json
>>> array = json.load({"name":"Galen","learning objective":"load json files for data analysis"})
Traceback (most recent call last):
File "<pyshell#1>", line 1, in <module>
array = json.load({"name":"Galen","learning objective":"load json files for data analysis"})
File "C:\Python34\lib\json\__init__.py", line 265, in load
return loads(fp.read(),
AttributeError: 'dict' object has no attribute 'read'

Since you want to convert it into jsonformat, you should use json.dumps()instead of json.load(). This would work:
既然你想把它转换成json格式，你应该使用json.dumps()而不是json.load(). 这会起作用：
>>> import json
>>> array = json.dumps({"name":"Galen","learning objective":"load json files for data analysis"})
>>> array
'{"learning objective": "load json files for data analysis", "name": "Galen"}'
Output:
输出：
>>> a = json.loads(array)
>>> a["name"]
u'Galen'

I think you are after this:
我认为你在追求这个：
import json
array = json.dumps({"name":"Galen","learning objective":"load json files for data analysis"})
print(array)
Gives:
给出：
{"learning objective": "load json files for data analysis", "name": "Galen"}

if you want to load json from a string you need to add quotes around your string and there is a different method to read from file or variable. For variable it ends with "s" other doesn't
如果您想从字符串加载 json，您需要在字符串周围添加引号，并且有一种不同的方法可以从文件或变量中读取。对于变量，它以“s”结尾，其他不
import json
my_json = '{"my_json" : "value"}'
res = json.loads(my_json)
print res

As you said, it is wrong, you forgot the ' before and after the json text.
正如你所说，这是错误的，你忘记了json文本前后的'。
import json
array = json.load('{"name":"Galen","learning objective":"load json files for data analysis"}')
I had the same mistake :)
我有同样的错误:)
dumps works but it is not the same. Load is better for parsing json. https://docs.python.org/2/library/json.html
转储有效，但不一样。Load 更适合解析 json。 https://docs.python.org/2/library/json.html
