解析电子邮件时仅使用Python进行回复时出错 [英] Error parsing emails for only replies with Python

问题描述

我有一个要解析的电子邮件的csv，在这里上传

I have this csv with a bunch of emails that I want to parse, uploaded here

使用此图书馆，并感谢

Using this library and thanks to this answer, we have this loop that would go over the CSV and apply the cleaning function EmailReplyParser.parse_reply(email_message) to each message:

from email_reply_parser import EmailReplyParser
import csv
with open('D:/Harry_Potter.csv', encoding="utf8") as inf:
    reader = csv.reader(inf.readlines())
with open('D:/clean.csv', 'w') as outf:
    writer = csv.writer(outf)
    # need to skip the title
    title = reader.__next__()
    for row in reader:
        EmailReplyParser.parse_reply(row[0].split()[-1])
    writer.writerows(reader)

但是，这不起作用.

它循环得很好，但是电子邮件不会被清除.当我尝试使用从CSV粘贴的单个邮件副本进行尝试时，

It loops just fine, but emails are not cleaned. When I try it with a single message copy pasted from the CSV,

email = """I don't have an owl

它给了我正确的结果，就像这样:

It gives me the right result, like so:

EmailReplyParser.parse_reply(email)
Out[11]: "I don't have an owl"

为什么无法正确读取CSV?(我已经上传了CSV，因此无需下载即可尝试使用.)

Why is the CSV not being read correctly? (I've uploaded the CSV so that it can be tried without downloading).

推荐答案

我通过读取csv来简化解析csv行的方式，如下所示:

I simplified the way to parse a csv row by reading your csv like this:

with open('D:/Harry_Potter.csv', encoding="utf8") as inf:
    reader = csv.reader(inf)

然后更改您写入csv的循环.代码(更改用于打开/关闭文件的参数):

Then change your loop for writing to the csv. Code (change arguments for opening/closing the file):

from email_reply_parser import EmailReplyParser
import csv
with open('hp.csv', encoding="utf8") as inf:
    reader = csv.reader(inf)
    with open('out.csv', 'w') as outf:
        # need to skip the title
        title = reader.__next__()
        for row in reader:
            # you need to store the return value from 'parse_reply'
            get_reply = EmailReplyParser.parse_reply(row[-1]) 
            # check what reply you get here
            print("Reply:", get_reply)
            outf.write(str(get_reply))
