Understanding 'For' Loops in Programming

What is the primary purpose of a 'for' loop?

• To execute a block of code once

• To iterate over a sequence of elements

• To handle exceptions in code

• To define a function

Which part of the 'for' loop specifies the sequence to iterate over?

• The increment

• The iterable

• The condition

• The initialization

In a 'for' loop, what happens if the sequence is empty?

• The loop runs indefinitely

• The loop throws an error

• The loop does not execute

• The loop executes once

Which of the following is a valid use case for a 'for' loop?

• Checking if a number is prime

• Iterating over a list of numbers

• Declaring a variable

• Opening a file

What is a common mistake when using 'for' loops?

• Forgetting to initialize variables

• Using the wrong data type

• Not defining the loop variable

• Iterating over the wrong sequence
