Question 1:
Briefly respond to all the following questions. Make sure to
explain and backup your responses with facts and examples.
Consider the data flow “octopus,” as shown in Figure 8.1. How
can the analysis system gather data from all these sources that,
presumably, are protected themselves?
Length: Minimum of 600 words
Note: 1) Make sure to explain and backup your responses with
facts and examples. This assignment should be in APA format
and have to include at least two references.
2) Use the APA 7th professional template.
Question 2:
If an attacker can retrieve the API and libraries, then use these
to write an agent, and then get the attacker’s agent installed,
how should Digital Diskus protect itself from such an attack?
Should the business analytics system provide a method of
authentication of valid agents in order to protect against a
malicious one? Is the agent a worthy attack surface?

Functions
1. (20 points, 4 points each) True or False questions:
1) (4 points) (True/False) You must have a return statement in a
function

Answer:
2) (4 points) (True/False) When an argument with a default
parameter value is omitted in a function call, the interpreter
automatically passes the default parameter value in the call.
Answer:
3）(4 points) (True/False) A function cannot contain multiple
return statements.
Answer:
4) (4 points) (True/False) The following two print statements
output the same results:
def dif(length, width):
return length - width
print (dif (width = 10, length=2)) #1
print (dif (10, 2)) #2
Answer:
5) (4 points) (True/False) Once a code block terminates (e.g.,
when a function returns), all variables defined in that block “go
out of scope” and can no longer be accessed.
Answer:
2. (20 points, 4 points each) Multiple choice:

1) (4 points) A function with multiple parameters specifies them
in a(n) ________
a) semicolon separated list
b) comma-separated list
c) period-separated list
d) backslash-separated list
Answer:
2) (4 points) To define a function with an arbitrary argument
list, specify a parameter of the form:____
a) !args
b) #args
c) *args
d) ~args
Answer:
3) (4 points) To assign a value to a global variable in a
function, the global variable must be first declared in the
function
a) True
b) False
Answer:
4) (4 points) A statement in one function can access a local
variable in another function
a) True
b) False
Answer:
5) (4 points) The output for the following code is:
a) 9
def my_function (x):
x **2

print ( my_function (3))
b) 6
c) 8
d) None
Answer:
3. (20 points, 5 points each) Hand-trace the following code.
What is the output, or what error/problem do you observe and
why?
1) (5 points)
def cube (x):
return x ** 3
print(cube(2))
Output:
2) (5 points)
def my_function ( fname, lname):
print (fname + “ “ + lname)
my_function (“Emily”, “Chong”)
my_function (“Eddie”, “Lowes”)
my_function (“John”)
Output:

3) (5 points)
def main():
num1 = 10
num2 = 15
result = add() print(result)
def add(num1, num2):
return num1 + num2 main()
Output:
4) (5 points)
def main():
result = square(6) print('square(6):', result)
def square(number):
return number ** 2 main()# execution begins here
# when main returns, the script terminates here
Output:
4. (20 points) Define a maximum function that determines and
returns the largest of three values, calls the function three times
with integers, floating-point numbers, and strings, respectively
and print out the results.

For example:
maximum (15, 20, 36)
output is: 36
maximum (12,3, 17.8, 1.5)
output is: 1.5
maximum (‘apple’, ‘orange’, ’banana’)
output is: orange
· (15 points) Write the program here, or copy/paste the
screenshot of your program
· (3 points) Screenshot of a Program Run:
· (2 points) Save the program as “maximum.py”. Upload the .py
file as part of your submission.
Note:
You are implementing the maximum function in this exercise.
Actually, for many common tasks, the capabilities you need
already exist in Python. For example built-in function max() is
similar to what you are implementing here. Using built-in
functions or functions from the Python Standard Library’s

modules rather than writing your own can reduce development
time and increase program reliability, portability and
performance. For a list of Python’s build-in functions and
modules, please review here:
https://docs.python.org/3/library/index.html
5. (20 points) Implement a Fahrenheit function that returns the
Fahrenheit equivalent of a Celsius temperature. Use the
following formula:
F = (9 / 5) * C + 32
Use this function to print a chart showing the Fahrenheit
equivalents of all Cesium temperature in the range of 90-100
degrees (including 90 and 100 degrees). Use one digit of
precision of the results.
For example, some outputs:
· (15 points) Write your program here, or copy/paste a
screenshot of your Program:
· (3 points) copy/paste Program Run:

· (2 points) Save the program as “Fahrenheit.py”. Upload the
.py file as part of your submission.
6. Bonus Question: (20 points)
Write a recursive function for calculating n factorial: n!
Mathematically, n! = n x (n-1) x (n-2) x (n-3) x ……. x 3 x 2 x
1
From user input, get an integer number, print out the factorial
result for this number
Hint:
1) Decompose the original problem into simpler instance of the
same problem and get the recursive function, which is n! = n x
(n-1)!
2) Find the base/special case to terminate the recursion: 1! = 1
· (15 points) Write the program here, or copy/paste the
screenshot of your program
· (3 points) Screenshot of a Program Run:
· (2 points) Save the program as “factorialRecursive.py”.
Upload the .py file as part of your submission.

What to submit:
a) One word file (.doc(x)) named ”CSCI333-Assign5-
YourFirstLastName.doc”, including answers to all questions and
the python source code in text or screenshots of all programs.
b) All the Python source files (.py) of the programming
questions.
c) Create a folder named as “CSCI333-Assign5-
YourFirstLastName” and put the word file and Python source
files into one folder Submission
d) Zip (compress) the folder and submit the zipped file in
myLeo
Note: Partial credit will be given so do what you can and make
sure you show your work for each question. No credit be given
if no work is shown.
For example, as long as you submit the screenshot of the
programming result and the .py file, you will get the
corresponding points.
