What is JSON?

JSON stands for "JavaScript Object Notation." It is a widely used, language-agnostic data interchange format that is easy to read and write. JSON represents structured data as key-value pairs and can be used in various programming languages for data storage and exchange.

Here's a simple example of JSON data:

{

"name": "John Doe",

"age": 30,

"isStudent": false,

"hobbies": ["reading", "swimming", "hiking"],

"address": { "street": "123 Main St", "city": "Exampleville", "state": "CA" }

}

To convert Python data to JSON string:

import json as js

data = {"name": "Tom", "age": 20}

json_str= js.dumps(data)

print(json_str)

To convert JSON string to Python data structure,

import json as js

json_str = '{"name": "Tom", "age":20}'

data=js.loads(json_str)

print(data["name"])

What is YAML?

YAML, or "YAML Ain't Markup Language," is a human-readable data serialization format used for configuration files and data exchange. Its clean syntax and simplicity make it popular in software development and system administration.

Python converts into yaml:

import yaml

data = {"name": "Tom", "age":20, "city": "NewYork"}

yaml_data = yaml.dump(data,default_flow_style = False)

YAML convert into Python:

python_data = yaml.safe.load(yaml_data)

print(f"name: {python_data["name"]}")

Tasks:

1. Create a Dictionary in Python and write it to a JSON File.

   json.dumps(): used to convert Python dictionary to JSON string.

   

2. Read a JSON file services.json kept in this folder and print the service names of every cloud service provider.

json.load() takes a file object and returns the json object. A JSON object contains data in the form of key/value pair. The keys are strings and the values are the JSON types. Keys and values are separated by a colon. Each entry (key/value pair) is separated by a comma.

1. Read the YAML file using Python, file services. yaml and read the contents to convert yaml to json

   

   If you need to convert YAML to JSON, you can parse the YAML as we did above. In the next step, you can use the JSON module to convert the object to JSON.
