9. The ABC company has hired you as an intern on the coding team that creates e-commerce applications.

   You must write a script that asks the user for a value. The value must be used as a whole number in a calculation, even if the user enters a decimal value.

   You need to write the code to meet the requirements.

   Which code segment should you use?

   • totalItems = input(“How many items would you like?”)
   • totalItems = float(input(“How many items would you like?”))
   • totalItems = str(input(“How many items would you like?”))

11. HOTSPOT

    During school holidays, you volunteer to explain some basic programming concepts to younger siblings.
    You want to introduce the concept of data types in Python. You create the following three code segments:

    

    You need to evaluate the code segments.

    For each of the following statements, select Yes if the statement is true. Otherwise, select No.

    NOTE: Each correct selection is worth one point.

    

    

    Explanation:

    – Code Segment 1: You cannot convert str to int. x1 = “2” is a string. Therefore code will produce an error.
    – Code Segment 2: b = 1.5, which is a float.
    – Code Segment 3: c = 2.5, which is a float, not an int.

12. DRAG DROP

    Match the data type to the type operations.

    To answer, drag the appropriate data type to the correct type operation. Each data type may be used once, more than once, or not at all.

    The ABC Video company needs a way to determine the cost that a customer will pay for renting a DVD. The cost is dependent on the time of day the DVD is returned. However, there are also special rates on Thursdays and Sundays. The fee structure is shown in the following list:
    – The cost is $1.59 per night.
    – If the DVD is returned after 8 PM, the customer will be charged an extra day.
    – If the video is rented on a Sunday, the customer gets 30% off for as long as they keep the video.
    – If the video is rented on a Thursday, the customer gets 50% off for as long as they keep the video.

16. DRAG DROP

    You are writing a Python program. The program collects customer data and stores it in a database.

    The program handles a wide variety of data.

    You need to ensure that the program handles the data correctly so that it can be stored in the database correctly.

    Match the data type to the code segment. To answer, drag the appropriate data type from the column on the left to its code segment on the right. Each data type may be used once, more than once, or not at all.

      “years of service!”)
    • print(“Congratulations on” + str(int(end)-int(start)) +
      “years of service!”)
    • print(“Congratulations on” + int(end – start) +
      “years of service!”)
    • print(“Congratulations on” + str(end – start)) +
      “years of service!”)

    What is the result of each arithmetic expression? To answer, drag the appropriate expression from the column on the left to its result on the right. Each expression may be used once, more than once, or not at all.

    

    

20. DRAG DROP

    You are writing a Python program that evaluates an arithmetic formula.

    The formula is described as b equals a multiplied by negative one, then raised to the second power, where a is the value that will be input and b is the result.

    You create the following code segment. Line numbers are included for reference only.

    

    You need to ensure that the result is correct.

    How should you complete the code on line 02? To answer, drag the appropriate code segment to the correct location. Each code segment may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
