Answer

lexis

Answer

semantics

Answer

Question 2

DRAG DROP
Insert the code boxes in the correct positions in order to build a line of code which asks the user for
an integer value and assigns it to the depth variable.

(Note: some code boxes will not be used.)

$\"Certification$

Accepted Answer

$\"Certification$

One possible way to insert the code boxes in the correct positions in order to build a line of code
which asks the user for an integer value and assigns it to the depth variable is:
depth = int(input("Enter the immersion depth: "))
This line of code uses the input function to prompt the user for a string value, and then uses the int
function to convert that string value into an integer number. The result is then assigned to the
variable depth.

references:

Question 3

DRAG DROP
Arrange the binary numeric operators in the order which reflects their priorities, where the top-most

position has the highest priority and the bottom-most position has the lowest priority.

$\"Certification$

Accepted Answer

$\"Certification$

The correct order of the binary numeric operators in Python according to their priorities is:
Exponentiation (**)
Multiplication (*) and Division (/, //, %)
Addition (+) and Subtraction (-)
This order follows the standard mathematical convention of operator precedence, which can be
remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication/Division,
Addition/Subtraction). Operators with higher precedence are evaluated before those with lower
precedence, but operators with the same precedence are evaluated from left to right. Parentheses
can be used to change the order of evaluation by grouping expressions.
For example, in the expression 2 + 3 * 4 ** 2, the exponentiation operator (**) has the highest
priority, so it is evaluated first, resulting in 2 + 3 * 16. Then, the multiplication operator (*) has the
next highest priority, so it is evaluated next, resulting in 2 + 48. Finally, the addition operator (+) has
the lowest priority, so it is evaluated last, resulting in 50.

Question 4

Which of the following expressions evaluate to a non-zero result? (Select two answers.)

Accepted Answer

2 ** 3 / A - 2

Accepted Answer

4 / 2 * * 3 - 2

Answer

1 * * 3 / 4 - 1

Answer

1 * 4 // 2 ** 3

Question 5

DRAG DROP
Insert the code boxes in the correct positions in order to build a line of code which asks the user for a
float value and assigns it to the mass variable.

(Note: some code boxes will not be used.)

$\"Certification$

Accepted Answer

$\"Certification$

One possible way to insert the code boxes in the correct positions in order to build a line of code that
asks the user for a float value and assigns it to the mass variable is:
mass = float(input("Enter the mass: "))
This line of code uses the input function to prompt the user for a string value, and then uses
the float function to convert that string value into a floating-point number. The result is then assigned
to the variable mass.

Question 6

Python Is an example of which programming language category?

Accepted Answer

interpreted

Answer

assembly

Answer

compiled

Answer

machine

Question 7

DRAG DROP
Drag and drop the literals to match their data type names.
$\"Certification$

Accepted Answer

One possible way to drag and drop the literals to match their data type names is:
STRING: “All The King’s Men”
BOOLEAN: False
INTEGER: 42
FLOAT: -6.62607015E-34
A literal is a value that is written exactly as it is meant to be interpreted by the Python interpreter. A
data type is a category of values that share some common characteristics or operations. Python has
four basic data types: string, boolean, integer, and float.
A string is a sequence of characters enclosed by either single or double quotes. A string can represent
text, symbols, or any other information that can be displayed as text. For example, “All The King’s
Men” is a string literal that represents the title of a novel.
A boolean is a logical value that can be either True or False. A boolean can represent the result of a
comparison, a condition, or a logical operation. For example, False is a boolean literal that represents
the opposite of True.
An integer is a whole number that can be positive, negative, or zero. An integer can represent a
count, an index, or any other quantity that does not require fractions or decimals. For example, 42 is
an integer literal that represents the answer to life, the universe, and everything.
A float is a number that can have a fractional part after the decimal point. A float can represent a
measurement, a ratio, or any other quantity that requires precision or approximation. For example, -
6.62607015E-34 is a float literal that represents the Planck constant in scientific notation.

Question 8

How many hashes (+) does the code output to the screen?

$\"Certification$

Accepted Answer

five

Answer

one

Answer

zero (the code outputs nothing)

Answer

three

Question 9

DRAG DROP
Drag and drop the conditional expressions to obtain a code which outputs * to the screen.
(Note: some code boxes will not be used.)
$\"Certification$

Accepted Answer

$\"Certification$

One possible way to drag and drop the conditional expressions to obtain a code which outputs * to
the screen is:
if pool > 0:
print("*")
elif pool < 0:
print("**")
else:
print("***")
This code uses the if, elif, and else keywords to create a conditional statement that checks the value
of the variable pool. Depending on whether the value is greater than, less than, or equal to zero, the
code will print a different pattern of asterisks to the screen. The print function is used to display the
output. The code is indented to show the blocks of code that belong to each condition. The code will
output * if the value of pool is positive, ** if the value of pool is negative, and *** if the value
of pool is zero.
You can find more information about the conditional statements and the print function in Python in
the following references:

[Python Print Function]
