NPTEL The Joy of Computing using Python Week 7 Assignment Answers 2025

1. In the function play(), what is the significance of the variable turn?

• It tracks the number of dice rolls
• It ensures alternating turns between the two players
• It ends the game after a fixed number of turns
• It stores the winning score

Answer : See Answers

2. What happens in the code when a player rolls a number that moves them past position 100?

• The game ends and they win
• The player’s position resets to 0
• The player stays in the same position (doesn’t move)
• The player is forced to roll again

Answer :

3. What is the purpose of the following lines in the play() function?

• To restart the game
• To display final scores and exit if the player chooses not to continue
• To check if the player reached a snake
• To decide the winner

Answer :

4. If Ankan is at position 47 and the snakes dictionary contains 47:26, what will happen immediately after his dice roll moves him to 47?

• He will stay at 47
• He will move to 100
• He will go to 26
• The game will end

Answer :

5. What does the function show_board() attempt to do?

• Display current scores
• Roll the dice for both players
• Open and display the game board image
• Initialize the snake and ladder dictionaries

Answer :

6. Which of these functions is called after a player moves and before their position is printed?

• show_board()
• play()
• check_ladder() and check_snake()
• reached_end() only

Answer : See Answers

7. How many times is the line random.randint(1, 6) evaluated in one full round of both players’ turns?

• Once
• Twice
• Four times
• Depends on the player positions

Answer :

8. Which part of the code ensures that the game stops immediately when a player reaches exactly 100?

• if pp1 > end:
• if pp1 == 100:
• if reached_end(pp1):
• if check_ladder(pp1):

Answer :

9. Consider the following ladders dictionary (in the format bottom: top): ladders = {1: 38, 4: 14, 9: 31, 21: 42, 28: 84, 36: 44, 51: 67, 71: 91, 80: 100}

If a player is on 27, rolls a 1, and lands on 28, what will happen next?

• The player will stay on 28 because it’s not a ladder base
• The player climbs the ladder to 84
• The player must roll again because 28 is a special position
• The code throws an error because 28 is not handled explicitly

Answer :

10.

Why is the condition turn % 2 == 0 used in this part of the code?

• To check if the game has reached the second round
• To make sure player 2 only plays after player 1 wins
• To alternate turns between the two players using the value of turn
• To skip the dice roll for even-numbered turns

Answer : See Answers

• The output may appear in any order
• It will raise a syntax error due to duplicate elements
• The output will be a list with 2 elements

Answer :

14. What will be the final contents of the pouch?

• {‘potion’, ‘gem’}

• < class ‘str’ >
• < class ‘set’ >

Answer :

16. Which of the following statements is true?

• 2 2
• 3 2
• 2 3

Answer :

18. Dilrez tries to update a tuple. Find and fix the error:

What’s the issue?

• Syntax error in tuple
• Tuples are immutable
• Need to use append()

Answer :

• 4 2 (‘map’, ‘torch’)
• 4 2 (‘torch’, ‘map’)
• 2 2 (‘map’, ‘torch’)
• 4 4 (‘map’, ‘torch’, ‘torch’, ‘map’)

Answer :

20. Dilrez does the following:

Which of the following is true based on this setup?

• All three containers contain the same items and in the same order
• Only the pouch automatically removes duplicates
• backpack[1] and supply_list[1] give the same result
• Sets can be indexed just like lists and tuples

21. Why does the code return 1 when n == 0?

• Because 0 × anything is 0
• To stop the recursion at some point
• By mistake; it should return 0
• It helps to calculate square of the number

Answer :

22. What will be the return value of factorial(1)?

• 0
• 1
• It will call itself infinitely
• 2

Answer :

23. Identify the error in the following code:

• It will return 6
• No base case defined, will result in infinite recursion
• n is not decremented
• Syntax error

Answer :

24. What does the line n! = n × (n-1) × (n-2) × … × 1 represent in the comprehension?

• An infinite series
• A summation of natural numbers
• A recursive definition of factorial
• A non-recursive mathematical shortcut

Answer :

25.

How many recursive calls are made when he executes factorial(4)?

• 3
• 4
• 5
• Infinite

Answer :

26. Himmat accidentally writes:

What will happen if he calls factorial(0)?

• Returns 1
• Returns 0
• Throws a recursion error
• Returns -1

Answer :

27. What would be a correct way to make Himmat’s function handle negative numbers safely?

• Add return -1 for all inputs
• Add a base case if n < 0: return “Invalid input”
• Remove recursion altogether
• Multiply by -1 inside the function

Answer :

28. If Himmat’s function is modified as:

What happens when factorial(3) is called?

• Returns 6
• Returns 0
• Infinite recursion
• Error due to syntax

Answer :

What will be the output?

• “a”
• “”
