Generate Code Name

Requirements:

• load json data from a file

• accessing a value in a dictionary

• multiple elif

• format output text

• returning a value

Read a JSON file containing information about an operative. Based on that information, generate a code name for them.

We store seemingly useless information about our operatives, but, we are able to generate code names for them based on that useless information. Depending on the values of particular attributes, we can assign them a code name.

Code names come in two parts.

1. An adjective and,

2. A noun

The code name is both words put together. i.e., "Happy Foot"

The Adjective

The first word is chosen based on the operatives favourite color. See the chart below.

Color    Adjective
------------------
White -> Happy
Blue  -> Sad
Red   -> Angry
Pink  -> Manly

The Noun

The next word is chosen based on their Imperial Academy scores.

Score                Noun
---------------------------
score < 50           Dropout
50 <= score < 60     Sloth
60 <= score < 70     Guppy
70 <= score < 80     Mountain
80 <= score < 90     Warlock
score >= 90          Beast

Dictionary Specification

operative = {
    "fav_color": str,
    "name": str,
    "academy_score": int,
    "eye_color": str
}

Example case

An operative file containing:

operative = {
    "fav_color": "White",
    "name": "Jeff Bridges",
    "academy_score": 43,
    "eye_color": "Blue"
}

Would have the code name:

Happy Dropout

If testing manually, here is a pre-made JSON file you can use. Change the relevant values to test the different outcomes.

Starter Code

import json


def generate_code_name(file_name: str) -> str:
    """Generates a code-name using information within the file of an operative.
    
    Args:
        file_name: The name of the operative's secret file.
        The file contains a JSON representation of the operative.
        See the "Dictionary Specification" section in the description.

    Returns:
        A generated code-name for the operative.
    """

    return ""
