如何在python中按时间顺序排列事件和数据

我有一项任务，按时间顺序排列下面的数据，并根据时间戳列出数据。如何在python中按时间顺序排列事件和数据

如果有人能指导我完成逻辑，我可以尝试自己编写代码。

输入：

Timestamp   : 2017-02-13 12:07:25.040000 UTC 
Event Name  : linkManager/link-event 
DataFields  : [srcSwName:X, srcPortName:ethernet30, dstSwName:X, dstPortName:ethernet3, fabricLinkEventType:X reason:Port Down] 

Timestamp   : 2017-02-13 12:07:26.040000 UTC 
Event Name  : eventManager/event 
DataFields  : [srcSwName:X, srcPortName:ethernet30, dstSwName:X, dstPortName:ethernet3, fabricLinkEventType:X, reason:Port Down] 

Timestamp   : 2017-02-13 12:07:25.040000 UTC 
Event Name  : linkManager/link-event 
DataFields  : [srcSwName:X, srcPortName:ethernet29, dstSwName:X, dstPortName:ethernet3, fabricLinkEventType:X reason:Port Down] 

Timestamp   : 2017-02-13 12:07:26.040000 UTC 
Event Name  : eventManager/event 
DataFields  : [srcSwName:X, srcPortName:ethernet30, dstSwName:X, dstPortName:ethernet3, fabricLinkEventType:X, reason:Port Down] 

Timestamp   : 2017-02-13 12:07:25.040000 UTC 
Event Name  : eventManager/event 
DataFields  : [srcSwName:X, srcPortName:ethernet30, dstSwName:X, dstPortName:ethernet3, fabricLinkEventType:X, reason:Port Down]

预期输出：

Timestamp   : 2017-02-13 12:07:25.040000 UTC 
Event Name  : linkManager/link-event 
DataFields  : [srcSwName:X, srcPortName:ethernet30, dstSwName:X, dstPortName:ethernet3, fabricLinkEventType:X reason:Port Down] 

Timestamp   : 2017-02-13 12:07:25.040000 UTC 
Event Name  : linkManager/link-event 
DataFields  : [srcSwName:X, srcPortName:ethernet29, dstSwName:X, dstPortName:ethernet3, fabricLinkEventType:X reason:Port Down] 

Timestamp   : 2017-02-13 12:07:25.040000 UTC 
Event Name  : eventManager/event 
DataFields  : [srcSwName:X, srcPortName:ethernet30, dstSwName:X, dstPortName:ethernet3, fabricLinkEventType:X, reason:Port Down] 

Timestamp   : 2017-02-13 12:07:26.040000 UTC 
Event Name  : eventManager/event 
DataFields  : [srcSwName:X, srcPortName:ethernet30, dstSwName:X, dstPortName:ethernet3, fabricLinkEventType:X, reason:Port Down] 

Timestamp   : 2017-02-13 12:07:26.040000 UTC 
Event Name  : eventManager/event 
DataFields  : [srcSwName:X, srcPortName:ethernet30, dstSwName:X, dstPortName:ethernet3, fabricLinkEventType:X, reason:Port Down]

你可以找到一种方式来读取文件，每行有''检查'，如果它是'Timestamp'，'Event Name'或'Datafields'。如果是这样，将它追加到一个特定的列表中（每个变量列表中有一个列表：list_timestamp，list_event_name和list_datafields），然后你可以压缩你创建的列表，通过时间戳记压缩列表。在所有这些过程完成后，您可以使用'for循环'重新创建文件布局，同时用'.format（）'打印每个变量' –

让我们来想象这是一个文件

import itertools 

with open('filename') as f: 
    # Extract blocks by splitting on empty lines 
    blocks = [list(val) for key, val in 
       itertools.groupby(f, lambda x: bool(x.rstrip())) 
       if key] 

    # Now the top line on each block has a timestamp so compare it: 
    blocks.sort(key=lambda x: x[0].split(':')[-1]) 

with open('out_file', 'w') as f: 
    # Write back the blocks with a new line separator to new file: 
    for block in blocks: 
     f.writelines(block + ['\n'])

您需要read文件并加载它INT o，例如，list。然后将代表为UTC时区的TimeStamp的第一个值字段转换为timestamp。

例如：

Timestamp   : 2017-02-13 12:07:25.040000 UTC

包含2017-02-13 12:07:25.040000可以通过timestamp使用datetime模块类似这样的例子来代替：

from datetime import datetime 
a = '2017-02-13 12:07:25.040000' 
b = datetime.datetime.strptime(a, "%Y-%m-%d %H:%M:%S.%f").timestamp() 
print(b) 
>>> 1486984045.04

现在，您可以创建一个method或者你可以简单地用一个lambda像这样的功能：

# Note: x should be a string 
get_timestamp = lambda x: datetime.datetime.strptime(x, "%Y-%m-%d %H:%M:%S.%f").timestamp()

然后，您可以sort您的list由您的新method或lmabda函数返回timestamp数据。
