def min(*args, **kwargs):
    key = kwargs.get("key", None)
    if len(args) == 1:
        args = args[0]
    return sorted(args, key=key, reverse=False)[0]

def max(*args, **kwargs):
    key = kwargs.get("key", None)
    if len(args) == 1:
        args = args[0]
    return sorted(args, key=key, reverse=True)[0]
print(max(3, 2))
print(min(3, 2))
print(max([1, 2, 0, 3, 4]))
print(min("hello"))
print(max(2.2, 5.6, 5.9, key=int))
print(min([[1, 2], [3, 4], [9, 0]], key=lambda x: x[1]))

輸入為:

3
2
4
e
5.6
[9, 0]
