break

Description

Terminates the execution of a loop.

Syntax

loop:

break

else:

suite

loop

for or while loop.

Remarks

break may only occur syntactically nested in a for or while loop, but not nested in a function or class definition within that loop.

It terminates the nearest enclosing loop, skipping the optional else clause if the loop has one.

If a for loop is terminated by break, the loop control target keeps its current value.

When break passes control out of a try statement with a finally clause, that finally clause is executed before really leaving the loop.

A break statement executed in the first suite terminates the loop without executing the else clause’s suite.

Example 1

>>> for i in range(5):
...     if i == 3:
...         break
...     print i
...
0
1
2

Example 2

i = 0
while i < 10:
    try:
        if i == 5:
            break
        print i
        i += 1
    finally:
        print 'that line was executed, i = ', i
