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

ADD YOUR ADDITIONAL NOTES HERE:

  • Random Values are a number generated using a large set of numbers and a mathematical algorithm which gives equal probability to all number occuring
  • Random values are SUPER useful in coding, you need them SUPER often

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():
    x = random.randint(1,2)
    if (x==1):
        return("heads")
    else:
        return("tails")
print(coinflip())
print(coinflip())

tails
heads

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

Homework

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

import random
x = random.randint(1,100)
print("The random decimal number is " + str(x))
xbin = bin(x)
print("Converted to binary, it is " + xbin[2:])

The random decimal number is 76
Converted to binary, it is 1001100
