Since list and dictionary are both ways of storing sequential collections of variables or elements, the main difference falls within the parameters of their use. Lists are for ordered sequences of items, such as pulling up a character inventory when making a RPG program. A dictionary associates items with a key-value pair, saving time when searching for a specific element since the element sequentially of the stored info has no effect when searching for a specific value. To access the elements, a list needs indices while the dictionary uses only the key-values. The downside for speed of dictionary method though, is that list maintains the order.
The textbook uses this example of a dictionary in relation to caffeine content of drink;
"caffeine_content_mg = {
'Mr. Goodbar chocolate': 122,
'Red Bull': 33,
'Monster Hitman Sniper energy drink': 270,
'Lipton Brisk iced tea - lemon flavor': 2,
'dark chocolate coated coffee beans': 869,
'Regular drip or percolated coffee': 60,
'Buzz Bites Chocolate Chews': 1639
}
print(caffeine_content_mg) "
Whilst a list would look like this;
"# Apple (APPL) stock prices 2005-2010
prices = [
34.62, 76.30, 85.05,
180.05, 90.75, 211.98
]
print(prices )
# Delete 2005 stock price
prices.pop(0)
print(prices)
# Delete stock price value of 211.98
prices.remove(211.98)
print(prices)
# Add a new stock price
prices.append(650.00)
print(prices) "
In the dictionary example, the order of the drinks does not matter, just the database to be used for comparison. In the lists, the order sequentially listed is import because the value refer to a time range of 2005-2010.

Hey Everyone,
I am not sure why every time I post things it erases what I have typed. From what I have read, lists keep order based on how they are placed. Basically, a list is a collection of objects in a fixed order. While both save data, they do it in different ways. Lists and dictionaries don't necessarily need to consist of the same type of objects. Dictionary associates with a key value, while lists just contain values. Lists use square brackets[]. Dictionaries utilize the curved ones{}.
For instance, if you want to discuss grades, they will look like this.
a_list = [86, 92 , 74 ,65]
a_dict = {Sue= 86, Bob = 92, Stephen = 74, Tom = 65}
If you want to discuss hotel prices in Phoenix, Arizona, they will look like this
hotel_list = [75.50, 87.25, 125.60, 150.48]
hotel_dict = {Hilton = 75.50, Hyatt = 87.25, Holiday Inn 125.60, Best Western = 150.48}
Utilizing the dictionary, if you wanted to print the cost of the Hilton, you type print(hotel_dict[Hilton]) and it would pull up the cost and print 75.50.

Systems Analysis and Design Assignment
A senior systems analyst has tasked you with creating a presentation containing two different object-oriented model
classes.
Ensure you include the following criteria in your presentation:
Create a six-slide original presentation.
One slide should explain use case modeling.
One slide should explain class diagrams.
One slide should explain object-oriented (O-O) modeling.
One slide should highlight the differences between use case modeling, class diagrams, and object-oriented modeling.
One slide should cover the first O-O class.
One slide should cover the second O-O class.
Include a title slide and a reference slide that do not count toward the final slide count total.
Utilize bullets for textual information.
Utilize the notes section for additional information.
Include at least one graphic (pictures, graphs, etc.) for each phase that must be specifically related to the content.
Follow APA style formatting and guidelines.
For the first O-O class, identify the object, attributes, and methods using object-oriented modeling. List a minimum of three
attributes and three methods for the class labeled CAR. All explanations must be in the notes section of the slide.
For the second O-O class, create a use case model for the actor. He wants to start, go forward, and stop the car. The actor
is labeled as the driver. All explanations must be in the notes section of the slide.
Remember to compare your PowerPoint Presentation with the rubric before submitting it.
