In the following example, we are going to read a JSON file and then print out the data in the form of a dictionary. Thisjson.load()function reads the string from the JSON file. The json.load(file) function creates and returns a new Python dictionary with the key-value pairs in the J...
Python dictionariesare a built-indata typefor storingkey-value pairs. The dictionary elements are mutable and don't allow duplicates. Adding a new element appends it to the end, and in Python 3.7+, the elements are ordered. Depending on the desired result and given data, there are various ...
To test the code, simply run it in a tool of your choice. I’ll be using IDLE, a Python IDE. You should get an output similar to figure 1. In the first print we can see that the dictionary was correctly converted to a compact JSON string, as expected. In the second print we can...

JSON (JavaScript Object Notation) is a popular file format to present the structured data and transfer the data between the server and the application easily. You can convert any dictionary object into the JSON object by using dump() and dumps() methods
In this example, we first import thejsonmodule. We then define a sample JSON string and store it in the variablejson_str. To convert the JSON string to a Python object, we use thejson.loads()function, which takes a JSON string as input and returns a corresponding Python object. We stor...
Save the file as a JSON file named superheroes. Example 1: Loading JSON to Python dictionary Start by importing thejsonlibrary. We use the functionopento read the JSON file and then the methodjson.load()to parse the JSON string into a Python dictionary called superHeroSquad. That’s it!
To request JSON data from the server using the Python Requests library, call the request.get() method and pass the target URL as a first parameter. The Python Requests Library has a built-in JSON decoder and automatically converts JSON strings into a Python dictionary. If JSON decoding fails...
