Python distinct Examples

Example #1

File: test_table.py Project: chdoig/blaze

def test_Distinct():
    t = TableSymbol('t', '{name: string, amount: int32}')
    r = distinct(t['name'])
    print(r.dshape)
    assert r.dshape  == dshape('var * {name: string}')

    r = t.distinct()
    assert r.dshape  == t.dshape

Example #2

def test_Distinct():
    t = symbol('t', 'var * {name: string, amount: int32}')
    r = distinct(t['name'])
    print(r.dshape)
    assert r.dshape == dshape('var * string')
    assert r._name == 'name'

    r = t.distinct()
    assert r.dshape == t.dshape

Example #3

File: test_table.py Project: testmana2/blaze

def test_Distinct():
    t = TableSymbol("t", "{name: string, amount: int32}")
    r = distinct(t["name"])
    print(r.dshape)
    assert r.dshape == dshape("var * string")
    assert r._name == "name"

    r = t.distinct()
    assert r.dshape == t.dshape

Example #4

def test_distinct():
    dftoobig = DataFrame(
        [['Alice', 'F', 100, 1], ['Alice', 'F', 100, 1], [
            'Alice', 'F', 100, 3
        ], ['Drew', 'F', 100, 4], ['Drew', 'M', 100, 5], ['Drew', 'F', 100, 4],

        columns=['name', 'sex', 'amount', 'id'])
    d_t = distinct(tbig)
    d_df = compute(d_t, dftoobig)
    tm.assert_frame_equal(d_df, dfbig)
    # Test idempotence
    tm.assert_frame_equal(compute(d_t, d_df), d_df)
