The problem with None in Python

[[python-custom-classes#Creating unique values]]

Unique sentinel values, identity checks, and when to use object() instead of None

def min(iterable, default=None):
    """Imperfect re-implementation of Python's built-in min function."""
    minimum = None
    for item in iterable:
        if minimum is None or item < minimum:
            minimum = item
    if minimum is not None:
        return minimum
    elif default is not None:
        return default
    else:
        raise ValueError("Empty iterable")
