Python - Chapter 5 Practice Quiz

What does a basic if statement in Python do?

• It checks a condition and runs code only if the condition is true.

• It allows for the creation of loops.

• It is used to declare variables.

• It is used to handle exceptions.

In Python, what is crucial for defining a code block within an if statement?

• Indentation

• Curly braces

• A colon

• Semicolon

What is the purpose of an if-else statement in Python?

• To check a condition and perform one action if true, and another if false.

• To create a loop that iterates over a range of numbers.

• To define a function that executes multiple commands.

• To import modules and libraries into a program.

In an if-elif-else statement, what happens when a condition evaluates to true?

• The block for the true condition is executed, and subsequent conditions are ignored.

• All conditions are evaluated regardless of the result.

• Only the else block is executed.

• None of the above.

What is the essential indentation consistency in programming?

• It refers to a uniform use of indentation as per style guidelines enhancing readability and reducing errors.

• It means that indentation is optional and can be random.

• It indicates that indentation can be varied arbitrarily without any impact.

• It is used only for visual appeal without functional significance.

Why is it important to avoid using both tabs and spaces for indentation in programming?

• It can cause inconsistent indentation, leading to unexpected behavior.

• It enhances the readability of the code.

• It makes the code run faster.

• It has no impact on the code's execution.

What is the syntax for a conditional expression (ternary operator) in Python?

• x if condition else y

• if condition then x else y

• x ? condition : y

• if (condition) { x } else { y }

What is the main advantage of using a conditional expression in Python?

• To enhance the readability of loops

• To allow inline decision-making with a concise syntax

• To facilitate the creation of classes

• To manage memory allocation
