Question

A Gumball machine has a number of different colors available: There are a random number of yellow, blue, white, green, black, purple, silver, cyan and magenta gumballs and one red gumball. With a pocket full of quarters, you have set your heart on getting that single red gumball. So, write a program that will simulate buying gumballs until you get the red one.

(Using Python) To start with, the number of gumballs for each color are randomly chosen as follows.

• Yellow - Between 10 and 15

• Blue - Between 1 and 10

• White - Between 6 and 15

• Green - Between 10 and 25

• Black - Between 1 and 12

• Purple - Between 5 and 10

• Silver - Between 4 and 6

• Cyan - Between 5 and 12

• Magenta - Between 0 and 10

• Red - 1 and only 1

You should first print out how many of each color are available at the start of your gumball buying spree. Then, you should randomly pick gumballs and print them out until you randomly pick the red one. At the end, you should print out how much total money you spent and also print out which color(s) you bought the most (which may be a tie!)

A sample run might look something like this:

Welcome to the CIMS Gumball Machine Simulator

You are starting with the following Gumballs:

5 Yellow

3 Blue

6 White

17 Green

6 Black

8 Purple

4 Silver

10 Cyan

2 Magenta

and 1 Yellow 

Here are your random purchases:

Green

Purple

Yellow

Green

Magenta

Magenta

Green

Yellow

Yellow

Red

You purchased 10 Gumballs, for a total of $2.50. 

The color(s) purchased most: Yellow Green

Answer 1

Here , i think their is one-misprint that is the yellow gumball is printed twice at the begining but no red gumball, so I corrected in in the code but i you have any doubt please feel free to ask.

Code :

import random
#create a list of Gumball
gumball = ["Yellow", "Blue", "White", "Green", "Black", "Purple", "Silver", "Cyan", "Magenta", "Red"]
#create a list of numbers of Gumball of each type available
gumball_count = [11, 3, 6, 17, 5, 8, 5, 7, 4, 1]

total_gumball_purchased = 0
#a list to store gumball of each type purchased
purchased_gumball_list = [0, 0, 0, 0, 0, 0, 0, 0, 0, 0]

#starting of the program
print("Welcome to the CIMS Gumball Machine Simulator")
print("You are starting with the following Gumballs: ")

#print all available Gumballs and their count
for count, gmball in zip(gumball_count, gumball):
print(count, gmball)

print("Here are your random purchase")
while True:
gumball_choice = random.choice(gumball)
total_gumball_purchased = total_gumball_purchased + 1
purchased_gumball_list[gumball.index(gumball_choice)] = purchased_gumball_list[gumball.index(gumball_choice)] + 1
print(gumball_choice)
if gumball_choice == "Red":
break

print("You purchased {0} gumball for a total of {1}".format(total_gumball_purchased, (0.25*total_gumball_purchased)))
#get max from list
get_max = max(purchased_gumball_list)
print("The color(s) purchased most : ", end="")
#print each gumball where index value is equal to get max
for index in range(len(purchased_gumball_list)):
if purchased_gumball_list[index] == get_max:
print(gumball[index], end=" ")
