Purpose/Objectives: Teach student how to implement randomness into their code to make their code simulate real life situations.

In this lesson students will learn:

  • How to import random to python
  • How to use random with a list or number range
  • How to code randomness in everyday scenarios

Summary (comprehensive notes are below)

  • Random values: Created using a mathematical algorithm that gives equal probability for generating numbers

ADD YOUR ADDITIONAL NOTES HERE:

Examples of where random variables can be applied: Games, statistical sampling, and cryptography.

What are Random Values?

Random Values are a number generated using a large set of numbers and a mathematical algorithm which gives equal probability to all number occuring

Each Result from randomization is equally likely to occur Using random number generation in a program means each execution may produce a different result

What are Examples of Random outputs in the world? Add a few you can think of.

  • Ex: Marbles

Why do we need Random Values for code?

Random values can be used in coding: 

import random
random_number = random.randint(1,100)
print(random_number)

def randomlist():
    list = ["apple", "banana", "cherry", "blueberry"]
    element = random.choice(list)
    print(element)
randomlist()

Real Life Examples: Dice Roll

import random
for i in range(3):
    roll = random.randint(1,6)
    print("Roll " + str(i + 1) + ":" + str(roll))

Challenge #1

Write a function that will a simulate a coinflip and print the output

import random
def coinflip():
    result = ["heads", "tails"]
    print(random.choice(result))
    
coinflip()

tails

EXTRA: Create a function that will randomly select 5 playing Cards and check if the 5 cards are a Royal Flush

NOTE: I didn't finish this extra challenge because I didn't have enough time.

cards = []
for suit in range(4):
    print(suit)
for i in range(1, 14):
    pass

0
1
2

Homework

Given a random decimal number convert it into binary as Extra convert it to hexidecimal as well.

def convert(num):
    numOfBinary = 8
    binary = []; 
    output = ""
    
    for i in range(numOfBinary): 
        binary.append((2**(numOfBinary - 1 - i)))
    
    for i in range(len(binary)):
        if num - binary[i] >= 0:
            num -= binary[i]
            output += "1"
        else: 
            output += "0"
        
    print(output)
        
convert(25)
