Explanation of Solution
Sentinel:
The special value, which signals that there are no more items from the list of items to be processed, is called as sentinel.
- Sentinel is used to hold special values to indicate that the user cannot enter additional values.
- It means when the user, the program, enters a sentinel value or loop control will be terminated.
- It is a value to indicate the user that the last grade of values has been entered.
- Sentinel value is used as a condition of termination in a recursive
algorithm or loop...

ASSIGNMENT BRIEF
Introduction
Roulette is a popular casino game named after the French word for 'little wheel'. In the game, players
may choose to place bets on single numbers or various groupings which will determine their payout.
To determine the winning number a ball is spun in the opposite direction of a spinning wheel. As the
ball loses momentum it comes to rest in one of the slots of the wheel.
Winnings are then paid to anyone who places a successful bet.

Numbers can be classified in several ways:
1. Red or Black
2. Odd or Even
3. High or Low - if a number is in the first half of the table it is considered low (1-18).
If a number is in the second half of the table, it is considered high (19-36).
4. Dozens - a number can be in the first dozen(1-12), second dozen (13-24) or third dozen (25-36)
5. Columns - A number may be in any of the three columns of the table
6. Zero - the number '0'…
check_game_over(): as the name suggests, this function should check to see if the game is over (if one side has no stones left in all of its pockets). It takes as an argument the game board and should return True if the game is over and False otherwise.

Then use the built-in function random first to generate a number between 0 and 6 (including). The expression (random) by itself generates a random integer. You can call it with one parameter to return a value within the range from 0 to the value of the parameter-1. For example, (random 10) will return a value between 0 and 9. Next, use the number generated at the previous step to retrieve the symbol for the day of the week from the list. Use the built-in elt. Extract the symbol-name of the day first, then apply the built-in function capitalize to it. Use the result in the princ function call, and do the same thing for the next day. Make the function return true (t) instead of the last thing it evaluates, to avoid seeing the message printed more than once.arrow_forward
- Golf scores record the number of strokes used to get the ball in the hole. The expected number of strokes varies from hole to hole and is called par (i.e. 3, 4, or 5). Each score's name is based on the actual strokes taken compared to par: "Eagle": number of strokes is two less than par "Birdie": number of strokes is one less than par "Par": number of strokes equals par "Bogey": number of strokes is one more than par Given two integers that represent par and the number of strokes used, write a program that prints the appropriate score name.
