首先，我们忽略了按块分组的概念，试图将每一行有效的数据作为字典。我们将把它存储在变量s中。你知道吗

filename = 'data.txt'
s = [ { x.split(':')[0] : x.split(':')[1].strip() } for x in open(filename).read().split('\n') if ':' in x ]

这将产生如下输出：

[{'inetnum': '193.194.64.0 - 193.194.95.255'}, {'netname': 'DZ-ARN-970407'}, {'descr': 'PROVIDER'}, {'descr': 'Algerian Academic Research Network'}, {'country': 'DZ'}, {'org': 'ORG-AARN1-AFRINIC'}, {'admin-c': 'EG71'}, {'tech-c': 'EG71'}, {'status': 'ALLOCATED PA'}, {'remarks': 'data has been transferred from RIPE Whois Database 20050221'}, {'notify': '***@arn.dz'}, {'notify': '***@arn.dz'}, {'mnt-by': 'AFRINIC-HM-MNT'}, {'mnt-lower': 'AS16214-MNT'}, {'changed': '***@ripe.net 19970407'}, {'changed': '***@ripe.net 19981020'}, {'changed': '***@ripe.net 19990104'}, {'changed': '***@ripe.net 20000309'}, {'changed': '***@ripe.net 20000428'}, {'changed': '***@ripe.net 20020313'}, {'changed': '***@afrinic.net 20050205'}, {'changed': '***@afrinic.net 20121211'}, {'changed': '***@afrinic.net 20180212'}, {'changed': '***@afrinic.net 20180228'}, {'source': 'AFRINIC'}, {'inetnum': '193.95.0.0 - 193.95.127.255'}, ... ]

现在我们找出分隔符（即，不带“：”的行）的位置。我们将它存储在变量t中。你知道吗

t = ''.join([ "1" if ':' in x else "0" for x in open(filename).read().split('\n')]).strip("0")

这将产生一个字符串，其中“1”表示普通行，“0”表示分隔符。你知道吗

'111111111111111111111111101111111111111111111111111111111011111111111111111111111101111111111111111111110111111111111111111111011111111111111111111111'

接下来，我们根据t中存储的模式将“0”分隔符添加到词典列表中。我们称之为w。你知道吗

w = [ s.pop(0) if int(x) else "0" for x in t ]

现在我们有了这样的东西：

[  ... {'changed': '***@afrinic.net 20170214'}, {'source': 'AFRINIC'}, '0', {'inetnum': '194.204.192.0 - 194.204.255.255'}, {'netname': 'ONPT'}, {'descr': 'Office National des Postes et Telecommunications'}, {'descr': 'aka Maroc Telecom'}, {'country': 'MA'}, ... ]

因此，我们可以找到“0”字符串的索引，并使用它们将此列表拆分为列表列表。我们还将使用过滤器从结果中删除“0”分隔符。你知道吗

indices = [ i for (i,x) in enumerate(w) if x == '0' ]
right = indices + [len(w)]
left = [0] + indices
result = [ list(filter(lambda x: x != "0", w[start:end])) for (start,end) in zip(left,right)]

所以现在result有了我们想要的输出，我们可以通过运行import pprint; pprint.PrettyPrinter().pprint(result)看到：

下面是我们编写的所有代码：

filename = 'data.txt'
s = [ { x.split(':')[0] : x.split(':')[1].strip() } \
     for x in open(filename).read().split('\n') if ':' in x ]
t = ''.join([ "1" if ':' in x else "0" \
             for x in open(filename).read().split('\n')]).strip("0")
w = [ s.pop(0) if int(x) else "0" \
     for x in t ]
indices = [ i for (i,x) in enumerate(w) if x == '0' ]
right = indices + [len(w)]
left = [0] + indices
result = [ list(filter(lambda x: x != "0", w[start:end]))  \
          for (start,end) in zip(left,right)]
