Expert Solution & Answer
Chapter 9, Problem 18SA
Explanation of Solution
Set “difference()” method:
- • The Python set is used to create the unordered collection of unique objects.
- • The built-in “set()” function is used in Python to create the sets.
- • The set difference operation is used to find the elements in a set that is not present in another set.
- • The “difference ()” method in Python is used to perform the set difference operation between sets.
- • Since the difference operation is not symmetric interchanging the operand sets will produce different results.
Syntax:
In Python, the “difference ()” method can be used to find the set difference of sets as follows:
set1.difference (set2)
Program:
#create the set set1 with three character type members
set1 = set(['d', 'e', 'f'])
#create the set set2 with five character type members
set2 = set(['a', 'b', 'c', 'd', 'e'])
#find the difference of set2 from set1
set3 = set2.difference(set1)
#display the difference set set3
print(set3)
Explanation:
In the above Python program,
- • The first statement is to create the set “set1” with elements “d”, “e”, and “f”...

ent, you'll need to build and run a small Zoo in Lennoxville. All classes must be created in
Animal (5)
First, start by building a class that describes an Animal at a Zoo. It should have one private instance
variable for the name of the animal, and one for its hunger status (fed or hungry).
Add methods for setting and getting the hunger satus variable, along with a getter for the name. Consider
how these should be named for code clarity. For instance, using a method called hungry () to make the
animal hungry could be used as a setter for the hunger field. The same logic could be applied to when it's
being fed:
public void feed () {
this.fed = true;
Furthermore, the getter for the fed variable could be named is Fed as it is more descriptive about what it
answers when compared to get Fed. Keep this technique in mind for future class designs.
Zoo (10)
Now we have the animals designed and ready for building a little Zoo!

- I want to ask someone who has experiences in writing physics based simulation software. For context I am building a game engine, and want to implement physics simulation.

The physics simulation starts. When that physics simulation starts, you are also having to update the physics through some physics dedicated delta time because physics needs to happen faster update frequency.
