Use a continue statement inside a for or while loop when you want
to jump directly back to the top of the loop and go
around again.
If used inside a while loop, the
loop's condition expression is evaluated again.
If the condition is False, the loop is
terminated; if the condition is True,
the loop is executed again.
Inside a for loop, a continue statement goes back to the top of the loop. If there
are any values remaining in the iterable that controls the
loop, the loop variable is set to the next value in the
iterable, and the loop body is entered.
If the continue is executed during the last
pass through the loop, control goes to the statement after
the end of the loop.
Examples:
>>> i = 0 >>> while i < 10: ... print i, ... i += 1 ... if (i%3) != 0: ... continue ... print "num", ... 0 1 2 num 3 4 5 num 6 7 8 num 9 >>> for i in range(10): ... print i, ... if (i%4) != 0: ... continue ... print "whee", ... 0 whee 1 2 3 4 whee 5 6 7 8 whee 9
