Question

Which structure (if, if-else, elif) allows us to look for a range of values, or an exact value?

a. if
b. if-else
c. elif

Answer 1

The 'if', 'if-else', and 'elif' structures can all be used to look for a range of values or an exact value. They differ in the way they handle multiple conditions by specifying alternative paths for the code to take depending on the result of the condition checks.

Step-by-step explanation:

The structures that allow us to look for a range of values or an exact value in programming are if, if-else, and elif. All three can be used to test for specific conditions; however, they serve slightly different purposes:

All three constructs are capable of evaluating whether a variable falls within a certain range of values or equals an exact value when paired with comparison operators such as '==', '>', '<', '>=', '<=', and '!='. Here's an example using an if-elif-else structure:

temperature = 75 if temperature > 80: print("It's too hot!") elif temperature < 60: print("It's too cold!") else: print("The temperature is just right!")

In the example above, the variable 'temperature' is checked against different ranges using the if and elif conditions, with a default action defined by the 'else' condition.
