1212 Midterm Review

What is printed by the following statement?

s = "Python" s[3] = "X" print(s)

• Python

• PyXhon

• ["P", "y", "t", "h", "o", "n"]

• Error will occur

• A user wants to figure out how much their Chick-fil-A order will be given the lists and tax provided in the picture (click to enlarge). Complete the following:

• 
  1. Print out the last element of the cfa_prices list

• 2. Write a program that calculates the total cost of a meal, including tax and tip, based on the cfa_menu and cfa_prices. The user will select a meal by entering an order number (1-4) and then provide a tip percentage. The program will compute and display the total price
  
  Have an output that looks similar to the following:

  Example Output: "Item: Grilled Chicken Sandwich Meal --> Total: $10.87"
  
  cfa_menu = ["Chicken Sandwich Meal", "Grilled Chicken Sandwich Meal", "Spicy Deluxe Meal", "8ct Nuggets Meal"]
  cfa_prices = [9.99, 8.99, 10.99, 8.59]

• tax = 7
  
  P.S It would be good practice to use Trinket as you will be using that workspace for the midterm

Match the following flowchart symbols with their corresponding actions:

• Flow Direction

• Parallelogram

• Input/Output

• Diamond

• Process

• Arrow

• Decision

• Oval

• Start or End

• Rectangle

 Select the correct option to fix this code so it correctly adds an integer input by the user:

user_input = input("Enter a number: ")

print(user_input + 2)

• str(user_input)

• float(user_input)

• len(user_input)

• int(user_input)

Given the list my_list = [10, 20, 30, 40, 50]:

What is the first element?; What is the len(my_list)?

• • 10; 5

• •  20; 5

• • 20; 4

• 10; 4

Match the following computer components with their purpose

• • Operating System

• Executes specific tasks and provides services to users

• RAM

• Facilitates communication between user and computer (e.g., keyboard, monitor)

• I/O Devices

• Temporarily stores data that the CPU needs to access quickly

• • Software

• • Manages computer resources and hardware

What is wrong with the following flowchart? (The intent is to print the temp is below freezing if 32 or less and print it is above freezing otherwise)

What will the following Python code print?

my_list = [1, 2, 3, 4, 5]

sliced_list = my_list[1:4] 

print(sliced_list * 2)

• [1, 2, 3, 4, 5, 1, 2, 3, 4, 5]

• [2, 3, 4, 2, 3, 4]

• [1, 2, 3, 4, 1, 2, 3, 4]

• [2, 3, 4]

• [4, 6, 8, 4, 6, 8]

What is the output of the following Python code?

result = ((10 + 3) * 2) // 4 + 10 % 3 print(result)

• 7

• 0

• 1

• 4

​ (a)   occurs when code violates the rules of the programming language, preventing proper interpretation or compilation.

​ (b)   occurs when the program runs but produces incorrect results. ​ (c)   occurs when the program attempts to perform an invalid operation during execution, such as dividing by zero.

• Syntax Error
• Semantic/Logic Error
• Runtime Error
