doc:product(*iterables) --> product object Cartesian product of input iterables. Equivalent to nested for-loops. For example, product(A, B) returns the same as: ((x,y) for x in A for y in B). The leftmost iterators are in the outermost for-loop, so the output tuples cycle in a manner similar to an odometer (with the rightmost element changing on every iteration). To compute the product of an iterable with itself, specify the number of repetitions with the optional repeat keyword argument. For example, product(A, repeat=4) means the same as product(A, A, A, A). product(\'ab\', range(3)) --> (\'a\',0) (\'a\',1) (\'a\',2) (\'b\',0) (\'b\',1) (\'b\',2) product((0,1), (0,1), (0,1)) --> (0,0,0) (0,0,1) (0,1,0) (0,1,1) (1,0,0) ...

public PyObject __iternext__()

Implements abstract org.python.core.PyIterator.__iternext__.

Doc from org.python.core.PyObject.__iternext__.

Return the next element of the sequence that this is an iterator for. Returns null when the end of the sequence is reached.

public PyObject next()

Overrides org.python.core.PyIterator.next.

Doc from org.python.core.PyIterator.next.

The exposed next method. Note that exposed derivable subclasses of PyIterator should override next to call doNext(custom___iternext__), as __iternext__ is overridden by the Derived classes.

Implements org.python.core.Traverseproc.refersDirectlyTo.

Doc from org.python.core.Traverseproc.refersDirectlyTo.

Optional operation. Should only be implemented if it is more efficient than calling traverse(Visitproc, Object) with a visitproc that just watches out for ob. Must return false if ob is null.

public int traverse(Visitproc visit, Object arg)

Overrides org.python.core.PyIterator.traverse.

Implements org.python.core.Traverseproc.traverse.

Doc from org.python.core.Traverseproc.traverse.

Traverses all directly contained PyObjects. Like in CPython, arg must be passed unmodified to visit as its second parameter. If Visitproc#visit(PyObject, Object) returns nonzero, this return value must be returned immediately by traverse. Visitproc#visit(PyObject, Object) must not be called with a null PyObject-argument.
