How to use 'iterable python' in Python

12
def isiterable(obj):
13
    """Returns `True` if the given object is iterable."""
14
    try:
15
        iter(obj)
16
        return True
17
    except TypeError:
18
        return False

6
def is_iterable(obj):
7
    """
8
    Robustly test whether an object is iterable.

    Parameters
11
    ----------
12
    obj : object
13
        The object to be checked.
14
15
    Returns
16
    -------
17
    is_iterable : boolean
18
        `True` if the object is iterable, `False` otherwise.

    Notes
21
    -----
22
    This test iterability by calling `iter()` and catching a `TypeError`.
23
    Various other ways might occur to you, but they all have flaws:
24
25
     * `hasattr(obj, '__len__')` will fail for objects that can be iterated
26
       on despite not knowing their length a priori.
27
     * `hasattr(obj, '__iter__')` will fail on objects like Theano tensors
28
       that implement it solely to raise a `TypeError` (because Theano
29
       tensors implement `__getitem__` semantics, Python 2.x will try
30
       to iterate on them via this legacy method if `__iter__` is not
31
       defined).
32
     * `hasattr` has a tendency to swallow other exception-like objects
33
       (`KeyboardInterrupt`, etc.) anyway, and should be avoided for this
34
       reason in Python 2.x, but `getattr()` with a sentinel value suffers
35
       from the exact same pitfalls above.
