98-381: Introduction to Programming Using Python

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?”))
totalItems = int(input(“How many items would you like?”))

Correct answer: B

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.

Correct answer: To work with this question, an Exam Simulator is required.

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.References: https://www.w3resource.com/python/python-data-type.php

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.

You are creating a Python program that shows a congratulation message to employees on their service anniversary.

You need to calculate the number of years of service and print a congratulatory message.

You have written the following code. Line numbers are included for reference only.

You need to complete the program.

Which code should you use at line 03?

print(“Congratulations on” + (int(end)-int(start)) + “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!”)

Correct answer: B

Explanation:

int must be converted to string

You are writing a Python program to perform arithmetic operations.

You create the following code:

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.

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.

NOTE: Each correct selection is worth one point.
