Python Coding challenge - Day 763| What is the output of the following Python Code?

 

Code Explanation:

1. Importing the json library

import json

We import the built-in json module.

This module helps us convert between Python objects and JSON strings.

2. Creating a dictionary

data = {"p": 2, "q": 5}

A dictionary data is created with two keys:

"p" → value 2

"q" → value 5.

3. Converting dictionary to JSON string

js = json.dumps(data)

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

Example: {"p": 2, "q": 5} becomes '{"p": 2, "q": 5}'.

4. Parsing JSON back to Python dictionary

parsed = json.loads(js)

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

Now, parsed is again: {"p": 2, "q": 5}.

5. Adding a new key-value pair

parsed["r"] = parsed["p"] ** parsed["q"]

parsed["p"] is 2, and parsed["q"] is 5.

2 ** 5 = 32.

So, a new key "r" is added with value 32.

Final dictionary: {"p": 2, "q": 5, "r": 32}.

6. Printing the results

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

len(parsed) → there are 3 keys in the dictionary (p, q, r).

parsed["r"] → value is 32.

Output:

3 32
