The :keyword:`break` statement breaks out of the innermost enclosing

The :keyword:`for` loop statements may have an extra :keyword:`!else` clause; it is executed when the loop
terminates through exhaustion of the iterable (with :keyword:`for`) or when the
condition becomes false (with :keyword:`while`), but not when the loop is

I find the original language here rather hard to parse because the concepts are quite unfamiliar (a loop that terminates through exhaustion of an iterable...).

Perhaps:

A for or while loop can include an else clause.

In a for loop, the else clause is executed after the loop reaches 88C1 its final iteration. In a while loop, it's executed after the loop's condition becomes false.

In either kind of loop, the else clause is not executed if the loop was terminated by a break.

This is exemplified by the following loop, which searches for prime numbers::
