# Dice rolling

This a problem set for you to work through [1]

This is a problem set. Some of these are easy, others are far more difficult. The purpose of these problems sets are:

1. to build your skill applying computational thinking to a problem
2. to assess your knowledge and skills of different programming practices

## What is this problem set trying to do

In this example we are learning about lists, conditionals, and processing user input.

## The Problem

Dice

A common mechanic in computer games is to simulate a dice roll. Please write a function that rolls dice for you and RETURNS the result.

for example: roll_dice(d6,3) <-- would roll a six sided die 3 times and return the result
for example: roll_dice(d12,1) <-- would roll a 12 sided dice 1 and return the result
for example: roll_dice(d20,4)  <-- would roll a 20 sided die 4 times and return the result.
You should model a 4 sided, 6 sided, 8 sided, 10 sided, 12 sided, 20 sided, and 100 sided die.
As extra-credit, you might want to return the result of each roll and then the final total.
for example: roll_dice(d6,3) <-- might return 6 3 1 10

## How you will be assessed

Scope

• To what extent does your code implement the features required by our specification?
• To what extent is there evidence of effort?

Correctness

• To what extent did your code meet specifications?
• To what extent did your code meet unit tests?
• To what extent is your code free of bugs?

Design

• To what extent is your code written well (i.e. clearly, efficiently, elegantly, and/or logically)?
• To what extent is your code eliminating repetition?
• To what extent is your code using functions appropriately?

Style

• To what extent is your code commented?
• To what extent are your variables well named?
• To what extent do you adhere to style guide?

import random
total = 0
def roll(sides):
sides = int(sides)
return random.randint(1,sides)

sides = input("Enter the number of sides on the dice: ")
times = input("Enter the number of times you are rolling: ")

times = int(times)
for x in range(times):
a = roll(sides)
print("roll is", a)

total = total + a

print("The total sum is", total)
