Python Coding challenge - Day 737| What is the output of the following Python Code?

Code Explanation:

1. Importing the Module

import json

We import the json module from Python’s standard library.

This module is used for working with JSON (JavaScript Object Notation) data.

Functions like json.dumps() and json.loads() help convert between Python objects and JSON strings.

2. Creating a Python Dictionary

data = {"a": 2, "b": 3}

A dictionary data is created with two key-value pairs:

"a": 2

"b": 3

3. Converting Dictionary to JSON String

js = json.dumps(data)

json.dumps(data) converts the Python dictionary into a JSON formatted string.

Example: {"a": 2, "b": 3} → '{"a": 2, "b": 3}' (notice it becomes a string).

4. Parsing JSON String Back to Dictionary

parsed = json.loads(js)

json.loads(js) converts the JSON string back into a Python dictionary.

Now parsed = {"a": 2, "b": 3} again (but it’s reconstructed).

5. Adding a New Key to Dictionary

parsed["c"] = parsed["a"] * parsed["b"]

A new key "c" is added to the dictionary.

Its value is the product of "a" and "b".

Calculation: 2 * 3 = 6.

Now dictionary = {"a": 2, "b": 3, "c": 6}.

6. Printing the Results

print(len(parsed), parsed["c"])

len(parsed) → Counts the number of keys in the dictionary → 3.

parsed["c"] → Fetches value of "c" → 6.

Output = 3 6.

Final Output:

3 6
