INTRODUCTION – Final Project

MODULE 5 GRADED ASSESSMENT

1. A programmer is working on a new project and encounters a complex problem. They are tempted to spend a lot of time trying to solve the problem on their own. However, a colleague advises them to research existing solutions first. What is the colleague’s advice based on?

2. Based on the following code, what is the correct output?

numbers = [ 4, 6, 2, 7, 1 ]
numbers.sort()
print(numbers)

3. What is the sort() method used for in Python?

4. You want to sort the following list in descending order. What is the correct code to use to do this?
numbers = [ 4, 6, 2, 7, 1 ]

5. You need to sort a list of strings based on their length, what argument would you use to do this?

6. Which of the following statements are true about Python dictionaries? Select all that apply.

7. Which of the following best describes the purpose of an if statement in Python?

8. A grocery store is developing a loyalty program to reward their customers based on their purchase history. The store wants to assign different reward tiers based on the total amount spent by each customer in the past year. To accomplish this, they need a conditional statement that will execute different blocks of code based on the customer’s spending amount. What conditional statement is most suitable for this task?

9. Take a look at the code snippet below. What is the purpose of the generate_report function?

def generate_report(machines):
for machine, users in machines.items():
if len(users) > 0:
user_list = ", ".join(users)
print("{}: {}".format(machine, user_list))

10. Why is understanding the problem essential to writing a Python script? Select all that apply.

11. You need to sort a list in descending order, which argument should you use in your sort() method to do this?

12. Based on the following code, what is the correct output?

names = ["Carlos", "Ray", "Alex", "Kelly"]
print(sorted(names, key=len))

13. A grocery store is tracking the inventory of its products. For each product, the store needs to keep track of the product name, the product ID, the quantity in stock, and the price.

14. A software engineer is tasked with developing a system that monitors network traffic and alerts administrators when suspicious activity is detected. The system receives a continuous stream of network traffic data, which needs to be processed and analyzed in real-time. The engineer is unsure of the best way to handle this high-volume data stream efficiently. What should the programmer do?

15. What does the following code snippet do?

if event.type == "login":
machines[event.machine].add(event.user)

16. Based on the following code, what is the correct output?

numbers = [ 3, 5, 4, 8, 1 ]
numbers.sort()
print(numbers)

17. What is the purpose of the argument key=len in a Python script?

18. A programmer is tasked with developing a program that processes events and prints the associated data to the screen. The programmer is unfamiliar with the most efficient approach to accomplish this task. What should the programmer do?

19. Which of the following statements accurately describes the purpose of an elif statement in Python?

20. Take a look at the code snippet below. What parameters does this method take in? Select all that apply.

class Event:
def __init__(self, event_date, event_type, machine_name, user):
self.date = event_date
       self.type = event_type
       self.machine = machine_name
       self.user = user

21. Restate the problem statement from the video example.

22. There are two standard methods to sort a list in Python, sort and sorted. What is the difference between these two methods?

23. Having a plan is half the battle. When planning out your program, why is it often a good idea to separate functions?

24. It’s important to know why we’ve written a function. In the example used in the video (shown here), what is the purpose of “if len(users) > 0:” ?

def generate_report(machines):
  for machine, users in machines.items():
    if len(users) > 0:
      user_list = ", ".join(users)
      print("{}: {}".format(machine, user_list))

25. Which line from the program we just wrote combines each logged-in user attribute into one variable?

26. A software engineer is tasked with developing a new feature for a popular web application. The feature involves a complex algorithm that requires a significant amount of coding. The engineer is tempted to start writing the code from scratch, but their manager suggests taking a different approach. What is the manager’s recommendation based on?

27. A system administrator is managing a network of computers. Each computer has a set of users who are currently logged in. The administrator wants to be able to quickly look up the current users of a given computer. Which data structure is the most efficient for storing the current users of each computer?

28. Which method is used to sort a list and keep the original list in tact?
