Question 1

The __________ function reads a piece of data that has been entered at the keyboard and returns that piece of data,as a string,back to the program.
A) input()
B) output()
C) eval_input()
D) str_input()

Accepted Answer

The input() function is used to take input from the user at runtime and returns it as a string. This helps us to take dynamic input from the user and use that input in our program.

Question 2

In Python,math expressions are always evaluated from left to right,no matter what the operators are.

Accepted Answer

In Python, math expressions follow the order of operations, also known as operator precedence. This means that certain operators have higher priority and are evaluated first. The order of operations is as follows: parentheses, exponentiation, multiplication/division/modulo, and addition/subtraction. Therefore, math expressions are not always evaluated from left to right.

Question 3

What is the output of the following print statement?
Print 'I\'m ready to begin'
A) Im ready to begin
B) I\'m ready to begin
C) I'm ready to begin
D) 'I\'m ready to begin'

Accepted Answer

The backslash (\) is an escape character in Python used to include characters that would normally be interpreted differently, such as a single quote. In this case, the backslash before the apostrophe tells Python to include the apostrophe in the string as a regular character, not as the end of the string. Therefore, when we print the string, it will output with the apostrophe included and no backslash.

Question 4

What is the informal language,used by programmers use to create models of programs,that has no syntax rules and is not meant to be compiled or executed?
A) flowchart
B) algorithm
C) source code
D) pseudocode

Accepted Answer

Pseudocode is an informal language used by programmers to create models of programs. It has no syntax rules and is not meant to be compiled or executed. It helps programmers to plan and structure their code before they start writing actual code. Flowchart is another visual representation tool used to represent the flow of a program, but it is not a language. Algorithm is a set of instructions to accomplish a task, which can be expressed in any language, including pseudocode. Source code is actual code written in a programming language with syntax rules that can be compiled and executed.

Question 5

Computer programs typically perform three steps: input is received,some process is performed on the input,and output is produced.

Accepted Answer

This is a correct statement about the standard functionality of computer programs.

Question 6

Since a named constant is just a variable,it can change any time during a program's execution.

Accepted Answer

The whole point of a named constant is that it cannot change during a program's execution. If it could change, it would be a variable, not a constant.

Question 7

Comments in Python begin with the # character.

Accepted Answer

In Python, comments begin with the # character. Anything after the # character on a line is ignored by the Python interpreter.

Question 8

A(n)__________ is a diagram that graphically depicts the steps that take place in a program?
A) flowchart
B) algorithm
C) source code
D) pseudocode

Accepted Answer

A flowchart is a graphical representation of the steps that take place in a program. It helps in visualizing the logical flow of the program, making it easier to understand and debug. Algorithms, source code, and pseudocode are all related to programming but do not represent the program flow in a visual format.

Question 9

Which mathematical operator is used to raise 5 to the second power in Python?
A) /
B) **
C) ^
D) ~

Accepted Answer

The ** operator is used to raise a number to a power in Python. Therefore, 5**2 would be used to raise 5 to the second power.

Question 10

Python allows programmers to break a statement into multiple lines.

Accepted Answer

Python allows programmers to break a statement into multiple lines using the backslash (\) character or by enclosing the statement in parentheses (). This is helpful for writing more readable code or for breaking up long statements.

Question 11

Python formats all floating-point numbers to two decimal places when outputting with the print statement.

Accepted Answer

By default, Python does not format all floating-point numbers to two decimal places when outputting with the print statement. It only outputs the exact value of the floating-point number unless you specify the number of decimal places you want to display using string formatting or f-strings.

Question 12

The 	 escape character causes the output to skip over to the next horizontal tab.

Accepted Answer

The 	 escape character indeed causes the output to skip over to the next horizontal tab.

Question 13

According to the behavior of integer division,when an integer is divided by an integer,the result will be a float.

Accepted Answer

According to the behavior of integer division, when two integers are divided, the result will be an integer, and any remainder will be truncated/ignored. To get a float result, at least one of the operands needs to be a float or a decimal number.

Question 14

The line continuation character is a
A) #
B) %
C) &
D) \

Accepted Answer

The backslash (\) is the line continuation character in many programming languages including Python, Java, and C++. When a backslash is placed at the end of a line, it indicates that the line should be continued on the next line.

Question 15

In a print statement,you can set the __________ argument to a space or empty string to stop the output from advancing to a new line.
A) stop
B) end
C) separator
D) newLine

Accepted Answer

The "end" argument can be set to a space or empty string to stop the output from advancing to a new line. This means that the next print statement will continue on the same line.

Therefore, the correct choice is B.

Question 16

A flowchart is a tool used by programmers to design programs.

Accepted Answer

A flowchart is a graphical representation of an algorithm or process, which is used by programmers to design, document, and communicate how a program works.

Question 17

After the execution of the following statement,the variable sold will reference the numeric literal value as (n)__________ data type.
Sold = 256.752
A) int
B) float
C) str
D) currency

Accepted Answer

The variable sold is assigned a value with a decimal point, which makes it a floating-point number. Therefore, the best choice is B, which represents the float data type.

Question 18

After the execution of the following statement,the variable price will reference the value __________.
Price = int(68.549)
A) 68
B) 69
C) 68.55
D) 68.6

Accepted Answer

The integer function (int()) will always round down to the nearest integer, in this case to 68. Therefore, the variable price will reference the value 68.

Question 19

In Python,print statements written on separate lines do not necessarily output on separate lines.

Accepted Answer

In Python, print statements written on separate lines do not necessarily output on separate lines because Python automatically adds a newline character at the end of each printed line unless instructed otherwise.

Question 20

When using the camelCase naming convention,the first word of the variable name is written in lowercase and the first characters of all subsequent words are written in uppercase.

Accepted Answer

This is the rule for camelCase naming convention.

In Python,print statements written on separate lines do not necessarily output on separate lines.

When using the camelCase naming convention,the first word of the variable name is written in lowercase and the first characters of all subsequent words are written in uppercase.
