Suppose you want to change an existing program to have more of a modular architecture. The program contains a basic calculator program. Which of the following would be an appropriate attribute for the calculator class?(1 point) Responses subtraction subtraction number 1 number 1 calculate calculate addition addition

Answer 1

In the context of a calculator class, an appropriate attribute could be "addition" or "subtraction," depending on how you are designing your class. Typically, classes are designed to encapsulate data and behaviors together, so you could also consider the following:

1. Attributes (Properties): These would represent the state or data associated with your calculator. In this case, attributes like number1 and number2 (if you're taking two inputs for calculations) might be appropriate.

2. Methods (Behaviors): These would represent the actions that the class can perform. For example, calculate, which could act as a method that processes the desired operation based on user input for addition or subtraction.

Given the options you've provided, here’s a breakdown:

• subtraction: This could potentially represent a method in the class.
• addition: Similar to subtraction, this could also represent a method in the class.
• number 1: This could be an attribute to hold one of the numbers in the calculation.
• calculate: This would typically be a method to perform the calculation.

If you're looking for a clear attribute that fits the context of a calculator class, number1 could be the most appropriate choice from the provided responses. If you are trying to implement functionality, methods like addition and subtraction would be more suitable for that purpose.

So the best answer as an attribute would be number 1.

Answer 2

Which of the following would properly create a new student? class Student: def __init__(self, name, gpa, grade): self.name = name self.gpa = gpa self.grade = grade (1 point) Responses s1 = Student(self,“Jorge”, 3.4, 12) s1 = Student(self,“Jorge”, 3.4, 12) s1 = Student( “Jorge”, 12) s1 = Student( “Jorge”, 12) s1 = Student(3.4, “Jorge”, 12) s1 = Student(3.4, “Jorge”, 12) s1 = Student(“Jorge”, 3.4, 12)

Answer 3

To properly create a new instance of the Student class using the provided constructor, you need to pass the correct arguments in the correct order: name, gpa, and grade.

Given the constructor:

class Student:
    def __init__(self, name, gpa, grade):
        self.name = name
        self.gpa = gpa
        self.grade = grade

The correct instantiation must provide all three parameters. Therefore, the only correct option from your responses is:

s1 = Student("Jorge", 3.4, 12)

This correctly matches the parameters expected by the __init__ method of the Student class: name as a string, gpa as a floating-point number, and grade as an integer.

The other options either include incorrect parameters or miss some of the required parameters. So, in summary, s1 = Student("Jorge", 3.4, 12) is the proper way to create a new student instance.

Answer 4

The range function in Python has the definitions range(stop) or range(start, stop[, step]). The following code snippet will print the numbers 0-9 inclusive. for i in range(10): print(i, end = " ") print() How can the code be modified to change the output to be the numbers 1-10 inclusive? (1 point) Responses for i in range(1,11): for i in range(1,11): for i in range(0,10): for i in range(0,10): for i in range(1,10): for i in range(1,10): for i in range(10,1):

Answer 5

To modify the code to print the numbers 1 to 10 inclusive, you need to set the starting value to 1 and the stopping value to 11. The correct way to do this using the range function is:

for i in range(1, 11):
    print(i, end=" ")
print()

From the provided options, the correct response is:

for i in range(1, 11):

This defines the range starting at 1 and stopping before 11, which effectively gives you the numbers 1 through 10 inclusive when you print them.

The other options do not correctly define the range for printing the numbers from 1 to 10:

• for i in range(0,10): will print 0 to 9,
• for i in range(1,10): will print 1 to 9,
• for i in range(10,1): will not produce any output because it starts at 10 and goes to 1 (which is an empty range).

Therefore, the correct choice is for i in range(1, 11):.

Answer 6

The complex function in Python is a built-in function that stores numbers as complex numbers. The syntax is complex ([real[, imaginary]]). The following code prints out a real number in complex form. a = complex(1.5) print(a) How would the code need to be altered to change the number to have an imaginary part of 2? (1 point) Responses a = complex(2,1.5) a = complex(2,1.5) a = complex(1.5,2) a = complex(1.5,2) a = complex(2) a = complex(2) a = complex(1.5) b = complex(2

Answer 7

To change the number to have a real part of 1.5 and an imaginary part of 2 using the complex function in Python, you need to specify both the real part and the imaginary part in the correct order.

The syntax for the complex function is complex([real[, imaginary]]), where the first argument is the real part and the second argument (optional) is the imaginary part.

So to alter the code to have a real part of 1.5 and an imaginary part of 2, you would write:

a = complex(1.5, 2)
print(a)

From the provided responses, the correct choice is:

a = complex(1.5, 2)

This correctly creates a complex number with a real part of 1.5 and an imaginary part of 2.

The other options are incorrect for the following reasons:

• a = complex(2, 1.5): This creates a complex number with a real part of 2 and an imaginary part of 1.5, which is not what you want.
• a = complex(2): This creates a complex number with a real part of 2 and an imaginary part of 0.
• a = complex(1.5): This creates a complex number with a real part of 1.5 and an imaginary part of 0.
• a = complex(2): This is a repeat of the previous one, creating a complex number with a real part of 2 and an imaginary part of 0.
• a = complex(1.5) followed by b = complex(2): This is not a valid response since it does not assign a complex number with both required parts.

Thus, the proper response is a = complex(1.5, 2).
