"'NoneType' object is not subscriptable" OR "KeyError:" with openpyxl and ipwhois

Question

我正在编写一个 python3 脚本来执行以下操作：

在工作目录中打开一个 excel 文件
Select excel 文件中的第一个 sheet
Select 第三列中的所有数据（在本例中为 IP 地址范围）
遍历所有 IP 地址并为每个地址调用 whois API
将每个 IP 的结果存储在变量 (.json)
解析查找名称、IP 范围、联系信息的结果
将上面 6 中的值写入 excel 文件中的新行
在当前目录中以新名称保存excel文件

当前文档有一个包含 427 个唯一 IP 地址的列表，来自 whois api 的 RIPE 名称的结果是唯一的（有时在同一个响应中）。为了适应这一点，我遍历了每个 RIPE 名称以获取 ['contact'] 列表中的辅助数据集。只要联系人列表包含我想要的值，这就可以正常工作。如果没有，我会收到 NoneType 错误。我尝试使用 if 语句围绕此构建预防逻辑，其中 result == None 为我的变量分配 'NULL' 值，但随后我在 RIPE 名称上遇到 KeyError 异常。我被困住了，需要你的帮助。这是我的代码的副本：

import openpyxl

from pprint import pprint
from ipwhois import IPWhois

wb = openpyxl.load_workbook('Abuse Log with Notes FWC 2016-06-09.xlsx')#change name here to file to be used 
sheet = wb.get_sheet_by_name('Sheet1') #get first sheet in workbook

#Add new column headings for API results
sheet['E1'] = 'HOST NAME'
sheet['F1'] = 'HOST COUNTRY'
sheet['G1'] = 'IP START'
sheet['H1'] = 'IP END'
sheet['I1'] = 'HOST EMAIL'
sheet['J1'] = 'HOST PHONE'
sheet['K1'] = 'HOST ADDRESS'

#Store all start range IP's for Amazon in one list variable
AmazonStartIPs = [
  '54.64.0.0', '54.160.0.0','54.144.0.0',
  '52.64.0.0','54.208.0.0','54.192.0.0',
  '54.240.0.0','54.224.0.0','54.72.0.0',
  '54.176.0.0','52.32.0.0','52.0.0.0',
  '52.192.0.0','52.84.0.0','53.32.0.0']

def checkForAmazon():
   if StartAddress in AmazonStartIPs:
      Name = 'Amazon Web Services - Elastic Compute Cloud'
      CountryCode = 'US'
      AbuseEmail = 'abuse@amazonaws.com'
      AbusePhone = '+1-206-266-4064'
      AbuseAddress = ['410 Terry Avenue','North Seattle', 'WA', '98109-5210','UNITED STATES']

iterateColumn = sheet.columns[2]#get all cell values in column C
currentRowIndex = 2

for Address in iterateColumn[1:5]:#test range 1:5 to reduce API load
   ip_address = Address.value#set var to value of item in iterateColumn
      IP = IPWhois(ip_address)#store whois call in var of IP
      results = IP.lookup_rdap(depth=1)#call whois and store .json results

      Name = results['network']['name']#set name to IP Host name
      Name=''.join(Name)#formatting for excel

      CountryCode = results['asn_country_code']#var for country code
      CountryCode=''.join(CountryCode)

      StartAddress = results['network']['start_address']#var for IP range Start
      StartAddress=''.join(StartAddress)

      EndAddress = results['network']['end_address']#var for IP range End
      EndAddress = ''.join(EndAddress)

      #write values above to iterable rows in spreadsheet
      sheet.cell(row = currentRowIndex, column = 5).value = Name
      sheet.cell(row = currentRowIndex, column = 6).value = CountryCode
      sheet.cell(row = currentRowIndex, column = 7).value = StartAddress
      sheet.cell(row = currentRowIndex, column = 8).value = EndAddress

      for key in results['objects']:#get unique key values in results object
         r = key#store as var of r to prevent having to call by ripe name

      AbuseEmail = results['objects'][r]['contact']['email'][0]['value']
      if results['objects'][r]['contact']['email'] == None: 
         AbuseEmail = 'NULL'
      elif results['objects'] is None:
         AbuseEmail = 'NULL'

      sheet.cell(row = currentRowIndex, column = 9).value = AbuseEmail
      AbuseEmail = ''.join(AbuseEmail)

      if results['objects'][r]['contact']['phone'] == None:
         AbusePhone = 'NULL'
      else: 
         AbusePhone = results['objects'][r]['contact']['phone'][0]['value']

      sheet.cell(row=currentRowIndex, column = 10).value = AbusePhone
      AbusePhone = ''.join(AbusePhone)

      if results['objects'][r]['contact']['address'] == None:
         AbuseAddress = 'NULL'
      else:
         AbuseAddress = results['objects'][r]['contact']['address'][0]['value']

      sheet.cell(row=currentRowIndex, column = 11).value = AbuseAddress
      AbuseAddress =''.join(AbuseAddress)

      checkForAmazon()

      currentRowIndex += 1


rowsUpdated = sheet.max_row
print('{} records have been updated.'.format(rowsUpdated))

wb.save('ABUSE_IP_LOG_HOST_DATA.xlsx')

Answer 1

根据 MattDMo 的建议，我添加了以下异常处理并解决了问题：

try:
   AbuseEmail = results['objects'][r]['contact']['email'][0]['value']
   AbusePhone = results['objects'][r]['contact']['phone'][0]['value']
   AbuseAddress = results['objects'][r]['contact']['address'][0]['value']
except (KeyError, TypeError):
   AbuseEmail = 'NULL'
   AbusePhone = 'NULL'
   AbuseAddress = 'NULL'
