Question

我正在使用python 3.

我正在读取dictreader中的CSV文件，并试图查看哪个国家/地区的发生率最高。

注意我使用的是dictreader，而不是读者。我认为这是必要的，因为我正在使用Counter。

我遇到了麻烦，因为我的CSV文件中的某些行有空字节（特别是在密码字段中），这会导致我的脚本因csv阅读器不喜欢空字节而导致错误。这方面的一个例子是我在下面的评论中的最后一个样本行。我看到有些人用我的代码中的行删除空字节：readerobject(x.replace('\0', '') for x in csvfile)但是我似乎无法使用它，因为我已经将csvfile读入前一行的readerobject中。

这是我的代码

import codecs
from pprint import pprint  
from collections import Counter
import csv
linecount = 0
import time
country_counter = Counter()

print("parsing CSV log file")
with open('C:/Users/Home/Documents/kippo stuff/final lab/kippo/oldkippo4final.csv', newline='') as csvfile:
    readerobject = csv.DictReader(csvfile, delimiter=',', fieldnames=['Country', 'IP Address', 'Username', 'Password', 'Status', 'name', 'intention', 'OS'])
    readerobject(x.replace('\0', '') for x in csvfile)
    for row in readerobject:
        print(row, "\n\n")
        linecount +=1
        country_counter[row['Country']] +=1
        print(linecount)
print(country_counter.most_common(3))
print("the total linecount was: ", linecount)

空字节错误，希望在python
