Q.Participating in a quiz can be fun as it provides a competitive element. Some educational institutes use it as a tool to measure knowledge level, abilities and/or skills of their pupils either on a general level or in a specific field of study. Identify and analyse popular quiz shows and write a Python program to create a quiz that should also contain the following functionalities besides the one identified by you as a result of your analysis.
• Create an administrative user ID and password to categorically add, modify, delete a question
• Register the student before allowing her or him to play a quiz
• Allow selection of category based on subject area
• Display questions as per the chosen category
• Keep the score as the participant plays
• Display the final score

Structure the quiz around two dictionaries: questions[category] holding [text, options-tuple, correct-option] lists, and students mapping each registered player to a score. Admin functions (add / modify / delete a question) sit behind an ID + password check; players register, pick a category, answer each question and see a running verdict plus the final score.

questions = {'Science': [['Which gas do plants absorb...?',
                          ('Oxygen','Carbon dioxide','Nitrogen','Hydrogen'), 2]]}
if ans == correct: score = score + 1

Sample run: the admin adds a Science question, student Riya registers, plays the 2-question Science category, gets one right — final score 1 out of 2.

The idea. Analysing popular quiz shows (KBC-style ladders, rapid-fire rounds) yields the common core this program implements: a question bank organised by category, controlled admin maintenance of that bank, player registration, and transparent scoring shown at the end. Each question is [text, options-tuple, correct-option-number] — the options are a tuple (they never change one by one), while the question list itself is mutable so the admin can add, modify and delete.

Program:

ADMIN_ID = 'admin'
ADMIN_PW = 'quiz@123'

# questions[category] = list of [question_text, (options), correct_option_number]
questions = {
    'Science': [
        ['Which gas do plants absorb during photosynthesis?',
         ('Oxygen', 'Carbon dioxide', 'Nitrogen', 'Hydrogen'), 2],
    ],
    'Computer': [
        ['Which Python data type is immutable?',
         ('list', 'dictionary', 'tuple', 'set'), 3],
    ],
}
students = {}          # (roll, name) -> final score

Key lines:

• admin_login() compares the entered ID and password against the stored credentials; only then is the add/modify/delete submenu offered.
• questions.setdefault-style guard (if cat not in questions: questions[cat] = []) lets the admin create a brand-new category simply by adding a question to it.
• students[(roll, name)] = 0 registers the player before the quiz starts, as required, and the final score is written back to that entry.
• The play loop prints each option numbered, reads the choice, and either increments the score or reveals the correct answer — so the score is kept as the participant plays.
