A sequence index uses a built-in function called length or len() to provide a total number of elements in an ordered list. With which iteration does this function
work?

a for loop
a while loop
an infinite loop
a single statement loop

A sequence index uses a built-in function called length or len() to provide a total number of elements in an ordered list,the Iteration is used for a Loop Function

Explanation:

An iterative function is that function or one that loops to repeat some part of the code, whereas  a recursive function is one that calls itself again to repeat the code.

Using a simple for loop to display the numbers from one to ten is an iterative process.

When we execute  the first set of instructions  again, it is called an iteration. When a sequence of instructions is executed again and again in a  repeated manner, it is called a loop.
