在python中使用lambda和regex对列表排序

Question

list = ['xxxx ResultDatetime:2017-05-31 09:38:00.000:ResultDatetime', 'xxxx ResultDatetime:2017-05-26 15:36:00.000:ResultDatetime', 'yyyyy' ResultDatetime:2017-10-23 16:16:00.000:ResultDatetime]

datet = re.compile(r'ResultDatetime:(\d{4}-\d{2}-\d{2} \d{2}:\d{2})')

list.sort(key = lambda x: ........)

我想从最早的日期开始排序。我应该如何使用lambda和regex来实现呢？在

Answer 1

我认为最简单的解决办法是：

data  = ['xxxx ResultDatetime:2017-05-31 09:38:00.000:ResultDatetime',
         'xxxx ResultDatetime:2017-05-26 15:36:00.000:ResultDatetime', 
         'yyyyy ResultDatetime:2017-10-23 16:16:00.000:ResultDatetime']

sorted_data = sorted(data, key=lambda x: x[20:36])

print(sorted_data)

输出：

^{pr2}$
