It is structured, light weight, human readable and easy to parse. JSON is shorter, quicker and easier way to interchange data from server. Below is the sample code of JSON. Its very simple JSON code which gives us the list of users where each object contain the information like user id, name, email, gender and different contact numbers. Values may not be NaNs, infinities, or of any type not listed here.
Value: Each key has a value that could be primitive datatype integer, float, String etc. Apart from these there are some other methods for better parsing JSON data. It returns the value of object type. We pass the string type key and it returns the value in int type if exists otherwise it throws JSONException. It returns the value of Object type. We pass the String type key and it returns the value of Object type if exists otherwise it returns null.
We pass the String type key and it returns the value of Boolean type if exists otherwise it returns false. We pass the String type key and it returns the value in double type if exists otherwise it returns NaN.

Antony Hatchkins SirBenBenji Ensure the string you are trying to write to follow: str. SirBenBenji You can try using codecs too, as dinos66 specifies below — Shiv. See my solution for details.
Martin Thoma Martin Thoma Why do you use open for the reading but io. Is it possible to use io. If so, what parameters should be passed? In python2 codecs. One can say that this codecs. Welcome to Stack Overflow. If you decide to answer an older question that has well established and correct answers, adding a new answer late in the day may not get you any credit.
If you have some distinctive new information, or you're convinced the other answers are all wrong, by all means add a new answer, but 'yet another answer' giving the same basic information a long time after the question was asked usually won't earn you much credit. You show some sample data; that's good, but I'm not sure it's enough, especially as you don't show what is produced for the sample data.
I think the answer is ok because it contains more details and clarity. I don't have enough reputation to add in comments, so I just write some of my findings of this annoying TypeError here: Basically, I think it's a bug in the json. Give reasons when you claim something to be wrong. Use nickname so the person gets notified. You cannot write comments, but you can read comments.

AntonyHatchkins You are right for the unicode part. I just realised for io package in Python 2, write needs unicode , not str. This code works for me even with python2. As well as with python2. Check it once again, plz. Vishal Gediya Vishal Gediya 1 1 silver badge 6 6 bronze badges.

Doesn't open 'data. All previous answers are correct here is a very simple example:! The accepted answer is fine. However, I ran into "is not json serializable" error using that. Here's how I fixed it with open "file-name.

JSONEncoder : """ Special json encoder for np types """ def default self, obj : if isinstance obj, np. Then exchange: elif isinstance obj, np.
What a roundabout way to do something really simple — user Such a weak point of such a standard as json. It got downvoted perhaps because nobody expects it to be that complicated me included , and it does not really answer the question, but in my case, I needed it.
