When the process is too long to view, use the documentation to explain what the process does

Randomization is everywhere in our lives

RANDOM(a, b) generates and returns a random integer from a to b

The random library must be imported to use it's function

random.choice can pick a random element from a list

random.shuffle can rearrange the elements of a list at random

You can use the ladder function in randrange and not include the maximum value

randint(start,stop) claims a random number from a range, randrange(start,stop,step)

generates a random number in a range by setting increments

Multiple Choice

What does the random(a,b) function generate?

A. A random integer from a to be exclusive

==B. A random integer from a to b inclusive.==

C. A random word from variable a to variable b exclusive.

D. A random word from variable a to variable b inclusive.

What is x, y, and z in random.randrange(x, y, z)?

==A. x = start, y = stop, z = step==

B. x = start, y = step, z = stop

C. x = stop, y = start, z = step

D. x = step, y = start, z = stop

Which of the following is NOT part of the random library?

==A. random.item==

B. random.random

C. random.shuffle

D. random.randint

Short Answer Question

  1. What is the advantage of using libraries?

Using libraries and importing allows us to use the code inside to achieve our goals more quickly and easily. Libraries simplify complex processes and contain procedures used in creating novel programs.

  1. Write a thorough documentation of the following code.
import random 

names_string = input("Give me everybody's names, seperated by a comma.")
names = names_string.split(",")

num_items = len(names)

random_choice = random.randint(0, num_items - 1)

person_who_will_pay = names[random_choice]

print(f"{person_who_will_pay} is going to buy the meal today!")

Eric is going to buy the meal today!

Documentation: First import the random library to use the code inside the library, these codes allow us to eliminate the need to define complex code to use, and then import the user to use the names in the library, the names are separated by splits using commas, each name will be by the corresponding index, then use random.randint to randomly select an index and output the names.

Coding Challenges!

REQUIRED: Create programs in python to complete the two task</p>

  1. Create a program to pick five random names from a list of at least 15 names
import random # import random library

nameList = ["Eric","Lily","Jack","Kerry","RJ","John","Ashley","Tony","Scott","Tim","Petter","Amy","Potter","Alle","Golf"] # create a nameList to be used

# Print 5 random names from nameList
i = 1
while i <= 5:
    randomNames = random.choice(nameList) # use random function from random library
    print(randomNames)
    i += 1

  1. Create a program to simulate a dice game where each player rolls two fair dice (6 sides); the player with the greater sum wins
import random

def rollDice(): # define how to roll dices
    firstRoll = random.randint(1,6)
    secondRoll = random.randint(1,6)
    score = firstRoll + secondRoll
    return score

# print their scores
playerAscore = rollDice()
print("PlayerA got",playerAscore)

playerBscore = rollDice()
print("PlayerB got",playerBscore)

# compare scoreA with scoreB
if playerAscore > playerBscore:
    print("playerA wins")
if playerAscore < playerBscore:
    print("playerB wins")
if playerAscore == playerBscore:
    print("Both them tied with",playerAscore)    

PlayerA got 9
PlayerB got 5
playerA wins
