【问题描述】:
我想使用IPWhois 解析一些 Apache 访问日志。
我想根据asn_description 字段对IPWhois 结果进行分组。
以下sn-p中的set和itertools.groupby()是不是会产生不同的结果?
descs = set()
with open(RESULTSFILE, 'a+') as r:
for description, items in groupby(results, key=lambda x: x['asn_description']):
print('ASN Description: ' + description)
descs.add(description)
print(descs)
例如
ASN Description: GOOGLE - Google LLC, US
ASN Description: AVAST-AS-DC, CZ
ASN Description: FACEBOOK - Facebook, Inc., US
ASN Description: AVAST-AS-DC, CZ
ASN Description: AMAZON-AES - Amazon.com, Inc., US
ASN Description: FACEBOOK - Facebook, Inc., US
ASN Description: AMAZON-02 - Amazon.com, Inc., US
ASN Description: AMAZON-02 - Amazon.com, Inc., US
ASN Description: GOOGLE - Google LLC, US
ASN Description: GOOGLE-2 - Google LLC, US
ASN Description: AMAZON-02 - Amazon.com, Inc., US
{'FACEBOOK - Facebook, Inc., US', 'AVAST-AS-DC, CZ', 'AMAZON-AES - Amazon.com, Inc., US', 'GOOGLE-2 - Google LLC, US', 'GOOGLE - Google LLC, US', 'AMAZON-02 - Amazon.com, Inc., US',

Set 会返回唯一的值,groupby 只返回连续的唯一值
