To define a function

• def

• continue

• class

• break

• assert

Answer explanation

The correct choice to define a function in Python is 'def'. This keyword is used to create a new function, while the other options serve different purposes in the language.

A logical operator

• and

• del

• finally

• for

• in

Answer explanation

The correct answer is 'and' because it is a logical operator used in programming to combine boolean expressions. The other options are not logical operators.

To break out of a loop

• break

• assert

• as

• and

Answer explanation

The correct choice to break out of a loop in programming is 'break'. This statement immediately terminates the loop, allowing the program to continue with the next statement following the loop.

A null statement, a statement that will do nothing

• pass

• or

• not

• nonlocal

• None

Answer explanation

The correct answer is 'pass', which is a null statement in Python that does nothing when executed. The other options do not serve this purpose.

Used with exceptions, a block of code that will be executed no matter if there is an exception or not

• finally

• False

• except

• else

• elif

Answer explanation

The 'finally' block in exception handling is executed regardless of whether an exception occurs or not. It is used for cleanup actions, ensuring that certain code runs after try and except blocks.

To declare a global variable

• global

• from

• for

• finally

• False

Answer explanation

To declare a global variable in Python, you use the keyword 'global'. This allows you to modify a variable outside of the current scope, making it accessible throughout the module.

Boolean value, result of comparison operations

• True

• return

• raise

• pass

• or

Answer explanation

The correct answer is 'True' because it represents a Boolean value resulting from comparison operations, indicating a condition is met. The other options do not represent Boolean values.

To exit a function and return a value

• return

• raise

• pass

• or

• not

Answer explanation

The correct choice is 'return' because it is the keyword used in programming to exit a function and send a value back to the caller. The other options do not serve this purpose.

A logical operator

• not

• nonlocal

• None

• lambda

• is

Answer explanation

The correct answer is 'not', which is a logical operator in Python used to invert the truth value of a condition. The other options do not serve as logical operators.

Used with exceptions, what to do when an exception occurs

• except

• else

• elif

• del

• def

Answer explanation

The correct choice is 'except', as it is used in Python to handle exceptions. When an exception occurs, the 'except' block allows you to define how to respond to that exception, making it essential for error handling.
