Roulette (Betting Game)

Posted on December 12, 2014 by Administrator Posted in Computer Science, Python - Intermediate, Python Challenges, Solved Challenges

Rules of the Game

A player starts the game with 10 chips.

For each game the player should be asked how many chips they want to bet. They should not be allowed to bet more chips than they actually own.

Then the user should be asked which number they want to bet on (between 0 and 10)

The user should be asked which colour they want to bet on:

Green (Number 0)
Red (for odd numbers)
Black (for even numbers)

The computer program should then “spin the wheel” by generating a random number between 0 and 10.

If the number generated matches the user’s number then the user should be given 10 times their initial bet.
If the number generated matches the user’s colour (green for 0, red for an odd number, black for an even number) then the user should be given twice their initial bet.
If none of the above two conditions are met, the user loses their bet.

At the end of each bet, the program should display the user’s total number of chips.

The player should be able to carry on playing for as long as they want unless they have lost all their chips. In this case the game should end.

The YOLO Challenge

Posted on December 11, 2014 by Administrator Posted in Computer Science, Python - Beginner, Python Challenges

The YOLO challenge consists of creating an acronym generator: a program that prompts the user to enter an expression or a sentence (e.g. “You only live once!”) and in return gives the acronym matching the user input (e.g. “YOLO”)

Learning Objectives

In this challenge you will further improve your string manipulation techniques and your use of lists in Python. You will investigate how to split a string into a list and how to iterate through each item of a list.

Tips

First you may investigate the split() method that can be used on any string:

myStr = "Millie,Luke,Will,Esther"
myList = myStr.split(" ")
#This would return a list as follows: ["Millie","Luke","Will","Esther"]

You may also look at the upper() and lower() method that can be used to convert a string to UPPERCASE or lowercase.
For instance:
myStr.upper() would convert the myStr string to uppercase.
To access specific characters of a string using their position you can use the following notation:myStr[0] (This would return the first character of a string called myStr).
Finally to iterate through all the values in a list, you may need to use a for loop:
```
myList = ["Millie","Luke","Will","Esther"]
for pupil in myList:
   print(pupil)
```

Your Turn

Use all of the above tips to complete the YOLO challenge:

Challenge #2

You may want to fine tune your code so that words like “the” or “a” are being ignored.

Fizz-Buzz Game

Posted on December 11, 2014 by Administrator Posted in Computer Science, Python - Beginner, Python Challenges, Solved Challenges

Fizz buzz is a group word game for children to teach them about division. Players take turns to count incrementally, replacing any number divisible by three with the word “fizz”, and any number divisible by five with the word “buzz”.

Fizz-Buzz Challenge

For this challenge you need to write a computer program that will display all the numbers between 1 and 100.

For each number divisible by three the computer will display the word “fizz”,
For each number divisible by five the computer will display the word “buzz”,
For each number divisible by three and by five the computer will display the word “fizz-buzz”,

This is what the output will look like:

We have started the game for you… Complete this code (see below) to finish this challenge.

Tip

To find out if a number can be divided by an other number, you will need to check the remainder of the division by using the % sign in Python. For instance:

So to check if number1 can be divided by number2, you can check if:
number1 % number2 == 0.

Challenge #2

Tweak this code to use the input command in Python. The program should ask the user to input numbers in order or type the word Fizz or Buzz when required. The program should check that the user has typed the right number or the right word and stop if not. It should then give the final score (How far the player completed the game).

Challenge #3

Improve this code further to give the players three lives. The player can make up to 3 mistakes. Each time they make a mistake they lose 10 points but carry on playing till they lose their three lives.
