openepda.main.is_array_like(x)

Check if a variable is array-like

Returns

True if x is a tuple, a list, a numpy.ndarray, or a subclass of these; False otherwise

Return type

bool

Examples

>>> i = 1; f = 1.1; st = 's'; bs = b'S'
>>> d = {1: 1, 2: 2}; s = {1, 2, 3}
>>> l = [1, 2]; t = (1, 2)
>>> arr = np.asarray([1, 2, 3]); m = np.array([1, 2, 3])
>>> is_array_like(i), is_array_like(f)
(False, False)
>>> is_array_like(st), is_array_like(bs)
(False, False)
>>> is_array_like(d), is_array_like(s)
(False, False)
>>> is_array_like(l), is_array_like(t)
(True, True)
>>> is_array_like(arr), is_array_like(m)
(True, True)

openepda.main.is_list_or_tuple(x)

Check if a variable is either a tuple or a list

Returns

True if x is a tuple or list, or a subclass of these; False otherwise

Return type

bool

Examples

>>> i = 1; f = 1.1; st = 's'; bs = b'S'
>>> d = {1: 1, 2: 2}; s = {1, 2, 3}
>>> l = [1, 2]; t = (1, 2)
>>> arr = np.asarray([1, 2, 3]); m = np.array([1, 2, 3])
>>> is_list_or_tuple(i), is_list_or_tuple(f)
(False, False)
>>> is_list_or_tuple(st), is_list_or_tuple(bs)
(False, False)
>>> is_list_or_tuple(d), is_list_or_tuple(s)
(False, False)
>>> is_list_or_tuple(l), is_list_or_tuple(t)
(True, True)
>>> is_list_or_tuple(arr), is_list_or_tuple(m)
(False, False)

openepda.main.split_array_data(data, how='max_length')

Parameters

how (str) – ‘max_length|most_common’

Examples

>>> split_array_data({2: [1, 2], '2a': [1, 4]})
({}, {2: [1, 2], '2a': [1, 4]})

>>> split_array_data({2: [1, 2], 3: [1, 2, 3], '3a': [1, 2, 4]})
({2: [1, 2]}, {3: [1, 2, 3], '3a': [1, 2, 4]})

>>> split_array_data({2: [1, 2, 3], 3: [1, 2], '3a': [1, 2]}, how='most_common')
({2: [1, 2, 3]}, {3: [1, 2], '3a': [1, 2]})
