Python is_sequence Examples

Example #1

File: linear.py Project: yurim373/Study

def shape(matrix):
    if not F.is_sequence(matrix): return None

    len1 = len(matrix)
    if not (len1 > 0 and F.is_sequence(matrix[0])): return None

    len2 = len(matrix[0])

    return [len1, len2]

Example #2

File: linearAlgebra.py Project: nbc-pet-task/functional.py

def shape(matrix):
    if not F.is_sequence(matrix): return None

    shapes = []
    acc_matrix = matrix

    while True:
        matrix_length = len(acc_matrix)
        shapes.append(matrix_length)

        if not F.is_sequence(acc_matrix[0]):
            return shapes
        acc_matrix = acc_matrix[0]

Example #3

File: test.py Project: nbc-pet-task/functional.py

 def test_is_sequence(self):
     self.assertEqual(F.is_sequence(_list), True)
     self.assertEqual(F.is_sequence(_tuple), True)
     self.assertEqual(F.is_sequence(_str), True)
     self.assertEqual(F.is_sequence(_dict), False)
     self.assertEqual(F.is_sequence(_class), False)

Example #4

File: mathExt.py Project: nbc-pet-task/functional.py

def sum(arg):
    if not F.is_sequence(arg): return None
    return F.reduce(arg, lambda a, b: a+b, 0)
