모든 서브넷과 IP 주소 범위가 겹치지 않도록 변경하는 CSV 파일을 만들려고했습니다. 원래의 질문은 여기에 Editing csv file to edit subnets so there is no overlap in IP ranges (ipaddress module in Python 3.3)입니다. 그러나 if 문이 ValueError을 멈추게하고 두 번째 문제가 실제로 문제가되지 않도록 수정했습니다. 이터레이터를 다시 설정할 수 있다면이 작업을 할 수 있다고 생각합니다. file1의 모든 행과 file2의 모든 행을 비교해야합니다. 난이 때반복자 오류 재설정
: 그것은 첫 번째 라인을 비교
import ipaddress
import csv
from csv import DictReader, DictWriter
with open(r'file1.csv', newline='') as fin3,\
open(r'file2.csv', newline='') as fin4,\
open(r'file3.csv', 'w', newline='') as fout3:
read3 = DictReader(fin3) # fin 3 and 4 are copies of the same file
read4 = DictReader(fin4)
writenum3 = DictWriter(fout3, fieldnames=read3.fieldnames)
writenum3.writeheader()
for line3 in read3:
line3['Range']=ipaddress.ip_network(line3['Range']) # Convert IP ranges to ip network object
for line4 in read4:
line4['Range']=ipaddress.ip_network(line4['Range']) # Convert IP ranges to ip network object
if line3['Range'].netmask < line4['Range'].netmask: # To avoid "Not contained in" errors
if line3['Range'].overlaps(line4['Range']): # Tests for IP overlap
lst=list(line3['Range'].address_exclude(line4['Range'])) # List of subnets excluding line4 subnet
print (lst) # Temporary to view contents of lst
for val in lst:
line3['Range']=val # New range
line3[' IPStart']=val.network_address #New net address
line3[' IPStop']=val.broadcast_address #New broadcast address
writenum3.writerow(line3) # Write lines
번째 라인 FILE1의 (헤더 생략) 파일 2의 (헤더 생략).
나는이 (file.seek(0) 사용) 한 :
import ipaddress
import csv
from csv import DictReader, DictWriter
with open(r'file1.csv', newline='') as fin3,\
open(r'file2.csv', newline='') as fin4,\
open(r'file3.csv', 'w', newline='') as fout3:
read3 = DictReader(fin3) # fin 3 and 4 are copies of the same file
read4 = DictReader(fin4)
writenum3 = DictWriter(fout3, fieldnames=read3.fieldnames)
writenum3.writeheader()
for line3 in read3:
line3['Range']=ipaddress.ip_network(line3['Range']) # Convert IP ranges to ip network object
fin4.seek(0)
for line4 in read4:
line4['Range']=ipaddress.ip_network(line4['Range']) # Convert IP ranges to ip network object
if line3['Range'].netmask < line4['Range'].netmask: # To avoid "Not contained in" errors
if line3['Range'].overlaps(line4['Range']): # Tests for IP overlap
lst=list(line3['Range'].address_exclude(line4['Range'])) # List of subnets excluding line4 subnet
print (lst) # Temporary to view contents of lst
for val in lst:
line3['Range']=val # New range
line3[' IPStart']=val.network_address #New net address
line3[' IPStop']=val.broadcast_address #New broadcast address
writenum3.writerow(line3) # Write lines
이 오류 ValueError: 'Range' does not appear to be an IPv4 or IPv6 network을 제공합니다. 나는 list() 방법을 시도하는 경우
는 (: Can iterators be reset in Python? 여기에서 설명) :
import ipaddress
import csv
from csv import DictReader, DictWriter
with open(r'file1.csv', newline='') as fin3,\
open(r'file2.csv', newline='') as fin4,\
open(r'file3.csv', 'w', newline='') as fout3:

line3['Range']=val # New range
line3[' IPStart']=val.network_address #New net address
line3[' IPStop']=val.broadcast_address #New broadcast address
writenum3.writerow(line3) # Write lines
는 그것은 AttributeError: 'list' object has no attribute 'fieldnames' 오류가 있습니다.
여기에 http://docs.python.org/3.4/library/itertools.htmltee()을 사용해야하는지 궁금하지만 여기서는 사용법이나 작동 여부를 잘 모르겠습니다.
이 내 파일 1과 파일 2입니다 :

어떤 도움이 이 일이 어떻게 이루어 지는지 알았습니다.
감사합니다, B0T
코드에서 주석이'# 핀 3과 4는 같은 file'의 복사본입니다, 그러나 당신은'다른 contenst을 공급 말한다 file1.csv'와'file1.csv'를 사용합니다. 이것의 의미는 무엇입니까? – martineau
@martineau 동일한 파일을 자신과 비교하는 방법에 대해 마음을 감쌀 수 없으며 csv dictreader/writer에 대한 좋은 예제를 찾을 수 없기 때문에 동일한 파일의 복사본을 사용했습니다. – CircuitB0T
