# Lab 9: Numpy Arrays

## Logistics

• Due: Thursday, June 18th no later than 11:59pm.
• Submission instructions: upload solution, entitled FirstName-LastNameLab9.py to the BrightSpace Lab 9 Dropbox.
• Deadline reminder: once this deadline passes, BrightSpace will no longer accept your Python submission and you will no longer be able to earn credit. Thus, if you are not able to fully complete the assignment, submit whatever you have before the deadline so that partial credit can be earned.

## Learning outcomes

Gain experience with numpy arrays and contine to practice object oriented programming.

## Background

In a modified game of Yahtzee, five six-sided dice are rolled once.

For this assignment, you will simulate this modified game of Yahtzee to determine how likely certain outcomes are.

In this modified version of Yahtzee, a High Roll occurs when each of the five dice is either a 5 or an 6. For example, 5-5-5-5-5 or 5-6-6-5-5 are High Rolls.

In this modified version of Yahtzee, a Three of a Kind occurs when three of the dice show the same number. The other two dice must not show this number. For example, 4-5-4-1-4 is a three of a kind, but 4-5-4-4-4 is not.

In this modified version of Yahtzee, a large straight occurs when the five numbers can be arranged consecutively (for example, 1-3-4-2-5 or 2-5-4-6-3).

## Hints

Numpy arrays have a lot of methods and the Numpy library contains a lot of functions that can take in arrays. You might want to look up the max, min, and sort methods, and the bincounts function. Or you might find even more useful functionality! Check out the documentation here. You may want to search the documentation.

## Assignment

• Download lab9.py, rename it according to the instructions above, and make sure you understand it.
• Take the program above and modify it by adding the missing methods such that when the program is run, it produces this output.

## Grading - 10 points

3 points - High Rolls are identified correctly.

3 points - Three of a Kinds are identified correctly.

4 points - Large straights are identified correctly.

## Grading turnaround

All labs graded with scores recorded in BrightSpace no later than office hours the following day.
