在我看来，MySQL中的TIME类型旨在表示时间间隔，就像Python中的datetime.timedelta那样。从您引用的文档中：TIME values may range from '-838:59:59' to '838:59:59'. The hours part may be so large because the TIME type can be used not only to represent a time of day (which must be less than 24 hours), but also elapsed time or a time interval between two events (which may be much greater than 24 hours, or even negative).
从date time.timedelta转换为datetime.time的另一种方法是将列类型更改为datetime，而不使用日期字段。
-插入：tIn = datetime.datetime(
year=datetime.MINYEAR,
month=1,
day=1,
hour=10,
minute=52,
second=10
)
cursor.execute('INSERT INTO TableName (TimeColumn) VALUES (%s)', [tIn])
-选择：cursor.execute('SELECT TimeColumn FROM TableName')
result = cursor.fetchone()
if result is not None:
tOut = result[0].time()
print 'Selected time: {0}:{1}:{2}'.format(tOut.hour, tOut.minute, tOut.second)
对datetime对象调用datetime.time()以获取时间对象。
