More Control Flow Tools
***********************

Besides the :keyword:`while` statement just introduced, Python uses the usual
flow control statements known from other languages, with some twists.
As well as the :keyword:`while` statement just introduced, Python uses a few more

Loop statements may have an :keyword:`!else` clause; it is executed when the loop

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 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::
