Instructions

Part 1: Simple Dice Game

You will create a simple betting game. Prompt the user for the bet amount, and prompt for a guess of a number rolled on a 6 sided die. If the guess is correct they win if not they lose. More details below.

1. First ask if the user wants to play based on a "yes" or "no" input.

   • If user enters "yes" then continue (see info in 2. and 3.)
   • If the user enters "no" display "Okay you don't want to play. Game Over."
   • If the user enters anything else display "Invalid input. Game Over."

2. If user plays the game prompt for two inputs and immediately convert them to integers.

   • betting amount prompt, use the following string in your code: "How much would you like to bet? (enter an integer less than or equal 100) "
   • guess number rolled prompt, "Guess number rolled on six sided die? (1-6) "
   • Note: the die roll result is given to you as the variable first_dice_roll in the file.

3. The game only works when the bet is less than or equal to 100, if they guess the die roll then they will win two times the amount of the bet. If they lose they will lose the bet. Use the following strings in the program. (Example strings for a bet too much and for a bet of 50)

   • "Sorry, bet is too much. Game Over."
   • "Congratulations, you w0n 100"
   • "Sorry, you lost 50"

Note: Refer to the Desired output section

Note: Complete the Analysis part below by replacing "Your Answer Here" with your answer.

Analysis

What error occurs if you put the string "five" when you prompt the user for the bet and guess (Remove "Your Answer Here" placeholder and replace with your answer below)

Error Type that occurs: "ValueError"

Why Does it occur? "This error happens because the program is trying to convert the string 'five' into a number using the int() function. The int() function can only convert strings that look like numbers (e.g., '50'), not words. Since 'five' can't be turned into a number, Python raises a ValueError."

Desired Output

• user doesn't want to play the game.

$ python simple_dice_game.py
Welcome to the Dice Game
Would you like to play? (yes/no) no
Okay you don't want to play. Game Over.

• invalid input

$ python simple_dice_game.py
Welcome to the Dice Game
Would you like to play? (yes/no) y
Invalid input. Game Over.

• valid bet and incorrect guess

Welcome to the Dice Game
Would you like to play? (yes/no) yes
How much would you like to bet? (enter an integer less than or equal to 100) 50
If you guess correctly you win 100
A six sided die will be rolled. Guess the number? (1-6) 2
Sorry, you lost 50

• valid bet, and correct guess

$ python simple_dice_game.py
Welcome to the Dice Game
Would you like to play? (yes/no) yes
How much would you like to bet? (enter an integer less than or equal to 100) 50
If you guess correctly you win 100
A six sided die will be rolled. Guess the number? (1-6) 1
Congratulations, you won 100

• invalid wager

$ python simple_dice_game.py
Welcome to the Dice Game
Would you like to play? (yes/no) yes
How much would you like to bet? (enter an integer less than or equal 100) 9001
Sorry, bet is too much. Game Over.

Part 2: Dice Game Double play

The modified program will allow the user the option of playing twice.

1. Copy your code from simple_dice_game.py and put in the proper location of dice_game_double_play.py i.e. below the comment # YOUR CODE BELOW

2. Keep track of the winnings or losses from the Part 1. i.e. positive if the user won and negative if they lost.

3. Prompt to see if the user wants to play again.

   • The bet is automatically double the bet from previous game (whether they won or not).
   • Use the following string (displayed for a bet of 50 originally) "We can play again if you bet 100? (yes/no) "
   • If they don't want to play display "Fine! You won 100"

4. If they want to play prompt them for a guess and immediately convert it to an integer.

   • Use the following string "You know the game, guess the die number? (1-6) "
   • Note: the die roll for the 2nd guess is given to you as the variable second_dice_roll in the file.

5. Handle the various outcomes of playing twice

   • Betting results of two games are: (Win, Win)(Lose, Win)(Lose, Lose)(Win, Lose)
   • Use the following display prompts (assume 50 bet):
     • "Lucky you, two wins! Total winnings 300"
     • "Lost first bet, but won second bet! Total winnings 150"
     • "You lost both bets. Total loss 150"
     • "Won first bet, but lost second bet. You are even."

Desired Output

• won original bet, won second bet
