@Joni是正确的，您需要使用
datetime。
from datetime import datetimefrom pymongo import Connection# i have updated and included the complete pre client = Connection('localhost', 27017)db = client['database'] # your database nameinoshare = db['inoshare']# convert your date string to datetime objectstart = datetime(2014, 9, 24, 7, 51, 04)end = datetime(2014, 9, 24, 7, 52, 04)inoshare.find( {'id_no': 1, 'datahora': {'$lt': end, '$gte': start}, 'porta': 'A0'})<pymongo.cursor.Cursor at 0x7f9aafd64a90>inoshare.find_one( {'id_no': 1, 'datahora': {'$lt': end, '$gte': start}, 'porta': 'A0'}){u'_id': ObjectId('5435be9ce7b9916e02ed2cb5'), u'datahora': datetime.datetime(2014, 9, 24, 7, 51, 5), u'id_no': 1.0, u'lab': u'2', u'porta': u'A0', u'sensor': u'1', u'valor': u'917'}显然我可以成功返回结果。也许您的数据已损坏，或者您应该发布所有代码供我们审核
