A roulette wheel has 38 spaces on it

/ Exams & Certification / By

A roulette wheel has 38 spaces on it. Of these spaces, 18 are black, 18 are red, and two are green. The green spaces are numbered 0 and 00. The red spaces are numbered 1, 3, 5, 7, 9, 12, 14, 16, 18, 19, 21, 23, 25, 27, 30 32, 34 and 36. The remaining integers between 1 and 36 are used to number the black spaces. Many different bets can be placed in roulette. We will only consider the following subset of them in this exercise:

Single number (1 to 36, 0, or 00)

Red versus Black

Odd versus Even (Note that 0 and 00 do not pay out for even)

1 to 18 versus 19 to 36

Write a program that simulates a spin of a roulette wheel by using Python’s random number generator. Display the number that was selected and all of the bets that must be payed. For example, if 13 is selected then your program should display:

The spin resulted in 13…

Pay 13

Pay Black

Pay Odd

Pay 1 to 18

If the simulation results in 0 or 00 then your program should display Pay 0 or Pay 00 without any further output.

The Correct Answer and Explanation is :

To simulate a roulette wheel spin in Python and display the corresponding bets, you can use the following code:

import random

def spin_roulette():
    """Simulates a single roulette spin and returns the winning number."""
    # Define the numbers on the roulette wheel
    red_numbers = {1, 3, 5, 7, 9, 12, 14, 16, 18, 19, 21, 23, 25, 27, 30, 32, 34, 36}
    black_numbers = {2, 4, 6, 8, 10, 11, 13, 15, 17, 20, 22, 24, 26, 28, 29, 31, 33, 35}
    green_numbers = {0, 00}

    # Simulate the spin
    result = random.choice(list(red_numbers | black_numbers | green_numbers))
    return result

def display_bets(result):
    """Displays the bets that must be paid based on the spin result."""
    print(f"The spin resulted in {result}...")

    if result == 0:
        print("Pay 0")
    elif result == 00:
        print("Pay 00")
    else:
        # Determine the color
        if result in red_numbers:
            print("Pay Red")
        else:
            print("Pay Black")

        # Determine if the number is odd or even
        if result % 2 == 0:
            print("Pay Even")
        else:
            print("Pay Odd")

        # Determine if the number is in the range 1 to 18 or 19 to 36
        if 1 <= result <= 18:
            print("Pay 1 to 18")
        else:
            print("Pay 19 to 36")

# Simulate a spin
result = spin_roulette()

# Display the bets
display_bets(result)

Explanation:

  1. Defining the Numbers:
  • The roulette wheel has 38 spaces: 18 red, 18 black, and 2 green (0 and 00).
  • We define sets for red numbers, black numbers, and green numbers.
  1. Simulating the Spin:
  • The spin_roulette function randomly selects a number from the combined set of red, black, and green numbers to simulate a spin.
  1. Displaying the Bets:
  • The display_bets function prints the result of the spin.
  • It then checks the result and prints the corresponding bets:
    • If the result is 0 or 00, it prints “Pay 0” or “Pay 00”.
    • If the result is a red number, it prints “Pay Red”; otherwise, it prints “Pay Black”.
    • If the result is even, it prints “Pay Even”; otherwise, it prints “Pay Odd”.
    • If the result is between 1 and 18, it prints “Pay 1 to 18”; otherwise, it prints “Pay 19 to 36”.

Example Output:

The spin resulted in 13...
Pay 13
Pay Red
Pay Odd
Pay 1 to 18

Note:

  • In this simulation, the number 00 is represented as 00. In actual Python code, you might need to represent it as a string or handle it differently, as 00 is not a valid integer literal.
  • This simulation assumes that all bets are placed and paid out according to the standard rules of roulette.

This approach provides a straightforward way to simulate a roulette spin and display the corresponding bets in Python.
