Practice - 5 Tasks

1fill in blank

💡 Hint

Common Mistakes

Starting the index at 1 instead of 0.

Using None which is not an integer index.

The current player index should start at 0 to represent the first player in the list.

2fill in blank

medium

Complete the code to move to the next player in a circular manner.

LLD

current_player_index = (current_player_index [1] 1) % total_players

💡 Hint

Common Mistakes

Using subtraction which moves backward.

Using multiplication or floor division which do not cycle properly.

Adding 1 moves to the next player, and modulo ensures it wraps around to the first player after the last.

hard

Fix the error in the code to correctly check if it is the last player's turn.

LLD

if current_player_index == [1] - 1:
    print("Last player's turn")

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Comparing to current_player_index - 1 which is always false.

Using 1 which is just the second player index.

The last player's index is total_players - 1 because indexing starts at 0.

4fill in blank

hard

Fill both blanks to create a function that returns the next player index given the current index and total players.

LLD

def get_next_player(current_index, total_players):
    return (current_index [1] 1) [2] total_players

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using subtraction which moves backward.

Using floor division which does not cycle properly.

Add 1 to move to the next player, then use modulo (%) to wrap around the player list.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that maps each player to their turn number starting from 1.

LLD

turns = {player: index [1] 1 for index, player in enumerate(players) if index [2] total_players - 1 and player != [3]

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using subtraction instead of addition for turn numbers.

Using greater than or equal instead of less than.

Checking player against a wrong value instead of None.

Add 1 to index to start turns from 1, use < to exclude the last player, and check player is not None.
