Actually, python is a easiest programming language. It is a dynamically typed programming language.Pseudo code for first module : 1. Import randint from random 2. Define class with name Dice. 3. Define attribute self.num_sides 4. set self.num_sides=6 5. Define function roll i.e. roll(self) a. use randint to get integer b/w 1 and self.num_sides b. return the integer Pseudo Code for second module: 1. Import dice class . 2. Declare an object of dice class. 3. Declare a list with name results. 4. for i in range (1,100) a. call function dice.roll() b. store result in variable with name result c. append result in list results 5. Print list results

Question

# For module1

import random

class Dice:

def __init__(self,dice_side = 6):

self.num_sides = dice_side

def roll(self):

return random.randint(1,self.num_sides)

# For module2

from first_module import Dice

result = []

for i in range(100):

dice = Dice()

result.append(dice.roll())

print("Result : \n",result)

Pseudocode - Revise module 2 in your pseudocode to add these steps:

Roll the dice 1000 times
Do not print the results
Instead, print the frequencies from a list called frequencies[]
1. Frequencies are the number of times each number appears
Add the titles to your bar chart
1. # They are string values that appear at the top
2. # List the titles for the x axis and the y axis of your chart
3. # See the example in the code to support your pseudocode
Render the chart to appear in a “dice_barchart.svg” file
Add your name to the chart’s title
Test your chart by dragging the file dice_barchart.svg into any Web browser window
If you see your bar chart with 6 columns, examine it
1. Hover your cursor over each column to see the values for 1000 dice rolls
Save your pseudocode as M5Lab2ii.docx

Python code - Revise module 2 in M5Lab2dice_hist.py to add these steps:

import Pygal # Pygal draws the bar chart or histogram for you
import the Dice class # from dice import Dice
declare the variable dice and assign the value to the class name Dice()
1. # variable_name = Class()
Declare an empty list called results
Declare an empty frequencies list for the tracking how often each die value appears
Declare a variable frequency and assign it to results.count(value)
1. # Tracks the number of times each value from 1-6 is rolled
print the frequencies # the format is print(listname)
Bar chart: declare a variable hist and assign it the value pygal.Bar()
Declare a hist.title variable and set the value to the following

Your Name - Results of 1000 6-Sided Dice Rolls
Replace “Your Name” with your name

Declare a hist.x_title and set the value to Result using a string
Declare a hist.y_title and set the string value to "How Often Did We Roll a 1, 2, 3, 4, 5, or 6?"

from first_module import Dice
result = []
for i in range(100):
dice = Dice()
result.append(dice.rol1())
print("Result : \n",result)

import random
class Dice:
def _init_(self,dice_side = 6):
self.num_sides = dice_side
def roll(self):
return random.randint(1,self.num_sides)
