What will the output be from the following code?
print("Hello world!\nHello world!")

• Hello world! Hello world!

• Hello world!
  Hello world!

• SyntaxError

• Hello world!

Answer explanation

The code prints 'Hello world!' followed by a newline and then 'Hello world!' again. The correct output format includes the newline, represented as
in HTML, making the correct answer 'Hello world!
Hello world!'.

What will the output be from the following code?
print("Hello" + str(2) + "world!")

• Hello world! Hello world!

• Hello2world!

• Hello Hello world! world!

• SyntaxError

Answer explanation

The code concatenates the string 'Hello', the string representation of the number 2, and 'world!'. This results in 'Hello2world!', making 'Hello2world!' the correct output.

What is syntax?

• Syntax is the word used to describe an error

• Syntax is the rules of the programming language

• It is used to read information

• It is used to output information 

Answer explanation

Syntax refers to the set of rules that define the structure of statements in a programming language. It dictates how code must be written for the compiler or interpreter to understand it, making 'Syntax is the rules of the programming language' the correct choice.

Code executed based on a condition being true

• Sequence

• Selection

• Iteration

• Variable

Answer explanation

The correct choice is 'Selection' because it refers to code that executes based on a condition being true, allowing for decision-making in programming. In contrast, 'Sequence' is for ordered execution, 'Iteration' for loops, and 'Variable' for data storage.

Code repeated / looped until a condition has been met or a set number of times.

• Sequence

• Selection

• Iteration

• Variable

Answer explanation

Iteration refers to the process of repeating a block of code until a specific condition is met or a predetermined number of times is reached. This distinguishes it from sequence (order of execution) and selection (conditional branching).

What does the following code do? myAge = int (myAge)

• Converts the var (variable) myAge to a string

• Converts the var (variable) myAge to a integer

• Converts the var (variable) myAge from a integer to a string

• Converts the var (variable) myAge to if statement

Answer explanation

The code 'myAge = int(myAge)' converts the variable myAge to an integer type. This is the correct choice, as it explicitly uses the 'int()' function to change myAge into an integer, not a string or any other type.

What is python named after

• The snake

• Television show called Monty Python

Answer explanation

Python is named after the television show Monty Python's Flying Circus, not the snake. The creator, Guido van Rossum, chose the name for its fun and irreverent nature, reflecting the language's design philosophy.

What will the output be from the following code?
print(Hello world!)

• Hello world!

• SyntaxError

• Hello world

• print(Hello world!)

Answer explanation

The code will raise a SyntaxError because 'Hello world!' is not enclosed in quotes. In Python, strings must be defined with either single or double quotes.

What does the term 'debug' mean?

• Identify errors and fix them.

• Making a calculation

• A set of instructions

• Looking at code

Answer explanation

The term 'debug' refers to the process of identifying errors in code and fixing them. This makes 'Identify errors and fix them' the correct choice, as it directly describes the debugging process.

What syntax can you use to insert a line break between strings so that they appear over multiple lines?

• /

• \n
