Python coalesce

coalesce.py

def coalesce(*args):
    """Returns the first not None item. Similar to ?? in C#.
    It's different from a or b, where false values are invalid.

    :param args: list of items for checking
    :return the first not None item, or None
    """
    return next((arg for arg in args if arg is not None))
