If you need to parse a JSON string that returns a dictionary, then you can use the json.loads() method. JSON data is represented as key-value pairs, similar to a Python dictionary. JSON (JavaScript Object Notation) is a popular way to structure data and is used to exchange information between a web application and the server. One of which is the loads () method for parsing JSON strings. For managing JSON files, Python has the json module. print(json.dumps(fcc_data, indent=4, sort_keys=True)) Python has in-built modules for various operations. We can also sort the keys in alphabetical order using the sort_keys parameter and setting that to True. In this example, we are going to have an indent of 4 spaces and print the data in an easier to read format. To fix that, we can use the json.dumps() method with the parameter of indent.
If we examine the printed data, then we should see that the JSON data prints all on one line.īut that can be hard to read.

This is what the entire code would look like: import json The final step would be to print the results. We can then parse the file using the json.load() method and assign it to a variable called fcc_data. This is an example of a "FileNotFoundError" if I misspell the fcc.json file name. Python has a built-in package called json, which can be used to work with JSON data. JSON is text, written with JavaScript object notation. If the file cannot be opened, then we will receive an OSError. JSON is a syntax for storing and exchanging data. We are using the with keyword to make sure that the file is properly closed. If we want to read that file, we first need to use Python's built in open() function with the mode of read. In this example, we have a JSON file called fcc.json which holds the same data from earlier concerning the courses offered by freeCodeCamp. Print(jess_dict) How to parse and read a JSON file in Python This is an example of JSON data for freeCodeCamp: With the help of the json module you can. How can I parse the data and use the result I think I need to use json.loads for this task, but I can't understand how to do it. Working with JSON in Python is rather simple as Python has a builtin module that does all the heavy lifting for you. The JSON syntax looks like a JavaScript object literal with key-value pairs.
