def first(iterable, default=None, key=None):
    """Return first element of *iterable* that evaluates to ``True``, else
    return ``None`` or optional *default*. Similar to :func:`one`.
    >>> first([0, False, None, [], (), 42])
    42
    >>> first([0, False, None, [], ()]) is None
    True
    >>> first([0, False, None, [], ()], default='ohai')
    'ohai'
    >>> import re
    >>> m = first(re.match(regex, 'abc') for regex in ['b.*', 'a(.*)'])
    >>> m.group(1)
    'bc'

    The optional *key* argument specifies a one-argument predicate function
    like that used for *filter()*.  The *key* argument, if supplied, should be
    in keyword form. For example, finding the first even number in an iterable:
    >>> first([1, 1, 3, 4, 5], key=lambda x: x % 2 == 0)
    4
