你可以将为每个键提供的信息元组（即和）进行比较year，month并将date其与来自的可用信息的相同子集进行比较today：
>>> import datetime
>>>
>>> def bad_food():
... today = datetime.datetime.now()
... past_due = {
... datetime.datetime(2020, 11, 24): ['chicken', 'soup', 'chips'],
... datetime.datetime(2020, 11, 27): ['lays', 'chilli'],
... }
... for key in past_due:
... if (key.year, key.month, key.day) == (today.year, today.month, today.day):
... print(past_due[key])
...
>>> bad_food()
['lays', 'chilli']

Mamba is a new state space model architecture showing promising performance on information-dense data such as language modeling, where previous subquadratic models fall short of Transformers. It is based on the line of progress on structured state space models, with an efficient hardware-aware design and implementation in the spirit of FlashAttention.
