Simulation

  • A simulation is an imitation of situation or process.(virtual experiment)
  • Simulation involve testing.
  • Simulation is more safer and efficient than experiment, however, some experiment can't be replace by simulation.

Hack #1

  • Create an idea for a simulation and describe it (you don’t actually have to code it just think about/answer the guiding questions).
  • My idea for a simulation is a car engine testing simulation. The simulation will run through different environment and each environment will have different chance to cause The engine to fail. The simulation will run until the engine fails and show how many test did engine lasted.

Hack #3

  • Describe the rolling dice simulation (answer guiding questions)
  • The rolling dice simulation chooses a random number from 1-6 that simulates rolling a dice. The advantages is that it is random. The disadvantage is that it is not related to a dice in the real world as it rolls random.

Hack #4

  • Add a feature onto the rolling dice simulation above
    • ex: a 14-sided dice or expand the purpose of the simulation (hint: use conditionals to make dice part of a game/real life situation)
import random

num_dice_input = input("How many times do you want to roll?")

def countInput(input_string):
    if input_string.strip() in {"1", "2", "3","4", "5", "6"}:
        return int(input_string)

num_dice = countInput(num_dice_input)

def rollDice(numDice):
    result = []
    for i in range(numDice):
        roll = random.randint(1, 6)
        result.append(roll)
    return result

roll_results = rollDice(num_dice)

def total(list):
    total = 0
    for number in list:
        number = int(number)
        total += number
    return total

sum = total(roll_results)

print("you rolled:", roll_results) 
print("The sum is: ", sum)

you rolled: [1, 4, 5, 3, 5, 5]
The sum is:  23

Extra Credit

  • The program randomly pick a test for the product, if the product meet some requirement, it will tell you if the product is good enough.
import random
test = random.randint(1,3)

if test == 1:
    print("The product is not capable")
if test == 2:
    print("Ok, but still needs testing")
if test == 3:
    print("It's all set")

It's all set
