Python Coding challenge - Day 807| What is the output of the following Python Code?

 

Code Explanatiion:

1. import json

This line imports Python’s json module, which is used for working with JSON data.

It allows converting Python objects to JSON strings and vice-versa.

2. data = {"name": "John", "age": 25}

A Python dictionary named data is created.

It contains two key-value pairs:

{

    "name": "John",

    "age": 25

}

3. js = json.dumps(data)

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

After conversion, js becomes:

'{"name": "John", "age": 25}'

Notice that the result is a string, not a dictionary.

4. length = len(js)

len(js) calculates the total number of characters in the JSON string.

It counts every character, including braces {}, quotes " ", spaces, colons :, and commas ,.

5. print(js[2], length)

js[2] prints the 3rd character of the JSON string (indexing starts from 0).

length prints the total character count.

Given the string:

{"name": "John", "age": 25}

 0 1 2 ...

At index 2, the character will be:

n

So the output will look something like:

n 27

Final Output:

n 27
