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
|
||||
that we will encounter in this chapter.

:keyword:`!break` and :keyword:`!continue` Statements, and :keyword:`!else` Clauses on Loops

============================================================================================

The :keyword:`break` statement, like in C, breaks out of the innermost enclosing

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

:keyword:`for` or :keyword:`while` loop.
|
||||
|
||||
Loop statements may have an :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
|
||||
terminated by a :keyword:`break` statement. This is exemplified by the
|

following loop, which searches for prime numbers::
|
||||
A :keyword:`!for` or :keyword:`!while` loop can include an :keyword:`!else` clause.
|
||||
|
||||
In a :keyword:`for` loop, the :keyword:`!else` clause is executed
|
||||
after the loop reaches its final iteration.
|

|
||||
In a :keyword:`while` loop, it's executed after the loop's condition becomes false.
|
||||
|
||||
In either kind of loop, the :keyword:`!else` clause is **not** executed
|
||||
if the loop was terminated by a :keyword:`break`.
|
||||
|

This is exemplified in the following :keyword:`!for` loop,
|

which searches for prime numbers::
