示例1: test_like
# 需要導入模塊: from blaze.expr import Symbol [as 別名]
# 或者: from blaze.expr.Symbol import like [as 別名]
def test_like():
t = Symbol('t', 'var * {name: string, city: string}')
data = [('Alice Smith', 'New York'),
('Bob Smith', 'Chicago'),
('Alice Walker', 'LA')]
assert list(compute(t.like(name='Alice*'), data)) == [data[0], data[2]]
assert list(compute(t.like(name='lice*'), data)) == []
assert list(compute(t.like(name='*Smith*'), data)) == [data[0], data[1]]
assert list(compute(t.like(name='*Smith*', city='New York'), data)) == [data[0]]示例2: sin
# 需要導入模塊: from blaze.expr import Symbol [as 別名]
# 或者: from blaze.expr.Symbol import like [as 別名]
