Question

我正在尝试从csv中读取IP地址并将其转换为IP范围，并按每个类别对它们进行排列/分组。

下面是我的代码：

def create_range(ip_addresses):
    groups = []
    for _, g in itertools.groupby(enumerate(sorted(ip_addresses)), lambda (i, x): i-int(x)):
       group = map(operator.itemgetter(1), g)
       if len(group) > 1:
           groups.append("{}-{}".format(group[0], str(group[-1])))
       else:
           groups.append(str(group[0]))
    return groups

ips = collections.defaultdict(list)

with open('some.csv') as csv_file:
    file_reader = csv.reader(csv_file)
    next(file_reader)
    for (ip, cat, typ) in file_reader:
        ip = ipaddress.IPv4Network(unicode(ip.strip()))
        cat = cat.strip()
        ips[cat.strip()].append(ip)
    resultIPranges = {org: create_range(ip_range) for cat, ip_range in ips.items()}

我的CSV如下：

csv_file = """ip, cat, typ
              50.102.182.2, myCompany, blue
              52.102.182.4, myCompany, blue
              52.102.182.1, myCompany, blue
              52.102.182.5, myCompany, blue
              52.102.182.3, myCompany, blue
              27.101.178.17, myCompany, blue
              27.101.178.16, hisComp, red
              27.101.178.15, hisComp, red
              23.201.165.7, hisComp, red
              55.200.162.10, hisComp, red
              55.200.162.12, hisComp, red
              55.200.162.13, hisComp, red
              55.200.162.11, hisComp, red
              30.101.102.4, hisComp, red
"""

当前问题/错误：

对于_，itertools.groupby（enumerate（sorted（ip_addresses）））中的g lambda（i，x）：i-int（x））：TypeError：int（）参数必须是字符串或数字，而不是“ IPv4Network”

Answer 1

据我了解，您的x是IPv4Network实例，而不是int；因此int(x)无法将其转换为int;

可以转换的事物是IPv4Address实例；所以我的看法是，您应该更改

 ip = ipaddress.IPv4Network(unicode(ip.strip()))

到

 ip = ipaddress.IPv4Address(unicode(ip.strip()))
