lambda:
timestamp.sort(key=lambda x: time.strptime(x, '%Y-%m-%d %H:%M:%S')[0:6], reverse=True)
list.sort:
def foo(x): return time.strptime(x, '%Y-%m-%d %H:%M:%S')[0:6]timestamp.sort(key=foo, reverse=True)

由于您的列表已經(jīng)按升序排列，我們可以簡單地反轉(zhuǎn)列表。
>>> timestamp.reverse()
>>> timestamp
['2010-04-20 10:25:38',
'2010-04-20 10:12:13',

'2010-04-20 10:11:50',
