示例1: test_simple_3
def test_simple_3(self):
element = Stream.range(100000) \
.filter(lambda x: x % 2 == 0) \
.map(lambda x: str(x)) \
.map(lambda x: 'Hi{0}'.format(x)) \
.map(lambda x: x.upper()) \
.filter(lambda x: x.endswith('8')) \
.limit(10) \
.map(lambda x: x[2]) \
.skip(1) \
.map(int) \
.list()
self.assertEquals(element, list(range(1, 10)))示例2: test_create_stream_with_list_params
