If you run the code above, you will get the data loaded into a Pandas dataframe.įigure 3 – JSON Data loaded as Pandas DataframeĪs you can see in the figure above, the read_json() method in Pandas reads the JSON from the string or a file and As you might be aware, Pandas is extensively used in the field of data science to analyze existing data and discover insights from the underlying data.

Now let us also take a look around the Pandas library in python and how to read and write data using Pandas. So far, we have learned about working with the JSON library in python to work with JSON data types. In case you would want to work with aĬustom data type, then we would first need to convert the custom datatype to a python dictionary object and then serialize it to JSON data format.

An important point worth mentioning is that the JSON library works only with the built-in python data types like string, integer, list, dictionaries, etc. Json.loads – This is similar to json.load, the only difference is it can read a string that contains data in theįrom my experience, I can say that you will be using the json.loads and json.dumps quite more frequently as compared to their streaming data counterparts. It parses theįile and then deserializes the data into a python object Json.load – You can use this method to load data from a JSON file that exists on the file system. The difference between both of these is that in the former, a stream of data is produced while the latter Json.dumps – This is used to serialize the python objects in the memory to a string that is in the JSON format. Json.dump – This method is used to serialize a python object from the memory into a JSON formatted stream that There are four basic methods in this library as follows: You can read more about this library from the official documentation. This is the default module provided by Python to deal and work with JSON data. If you see the code above, you will notice that I have imported the JSON module into the script. Let’s now understand and try to do this using python.įigure 2 – Console output from the above snippet The process of converting a string JSON into a python object is called Deserialization and the process of converting a python object back to JSON is called Serialization. In order for the machine to understand this string, it needs to be converted into an object which can be then consumed by the interpreter. The basic format of writing JSON is just a string data type that contains data in key-value pairs. While dealing with JSON, we often come across two terms known as Serialization and Deserialization of data. Now, we should understand how can we use this data in python and do operations as required. So far, we have understood how JSON looks like and how can we interpret a JSON data structure. The attributes and author are nested objects that can be further expanded to title, description,Ĭreated, updated and id, name respectively.īy having a quick glance at the overall data structure it is easy to determine the relationships between the articleĪnd the author and as such very easy to understand by both humans and machines.Ĭoncept of serialization and deserialization of the JSON The next items inside the list are the type, id, attributes, and author in regards to the article submitted. To keep things simple, I have only used one item on the list. Inside the braces, you can have multiple JSON nodes or strings as required. The top-level node of the sample is data under which a list is created by using the braces. The sample is a representation of this article. In the figure above you can see a sample data structure that is represented in JSON. In modern web applications, by default JSON is being used to transfer information.įirst, let’s begin by understanding how JSON looks and how to deal with it. In my opinion, JSON is much more human-readable as compared to XML, although both are used to store and transfer data. You can easily write simple and nested data structures using JSON and it can be read by programs as well. This is due to its easy-to-understand structure and also because it is very lightweight. JSON stands for Java Script Object Notation and has become one of the most important data formats to store and transfer data across various systems. In this article, I am going to write about the various ways we can work with JSON data in Python.
