if/elif/else conditionals

Question 1

True or false?

Inside an if/elif/else code block, if an expression is evaluated as True, then the code indented below the if statement will be executed. Otherwise, Python goes further and evaluates the elif or else statements, if any.

Answer 1

True

Question 2

True or false?

In Python, an if/elif/else code block may contain maximum two else clauses, as long as they are the last clauses in the block, after any if and elif clauses.

Answer 2

False. Only 1 else block can be used

Question 3

True or false?

The else clause gets executed if the expression in the if clause is evaluated as False and the expression in the elif clause is evaluated as True.

Answer 3

False. The elif clause was True.

Question 4

True or false?

You may have as many elif clauses as you need inside an if/elif/else code block.

Answer 4

True.

Question 5

True or false?

Every if clause must have at least one elif or else clause following it.

Answer 5

False.
