Python CSV:字段开头包含引号 [英] Python CSV : field containing quotation mark at the beginning

问题描述

我正在尝试读取包含以下内容的CSV文件:

I am trying to read a CSV file containing a line like following:

test,"test,"test,test,test,test

引号存在问题(有六个字段，但是它们被检索为五个字段，例如"test"，将test读取为单个字段).

There is a problems with the quotation marks (There are six fields, but they are retrieved as five fields, as "test,"test is read as a single field).

我尝试如下修改条目，但是仍然无法获取引号:

I have tried modifying the entry as follows, but I still can't retrieve the quotation mark:

test,""test,""test,test,test,test  # quotation marks disappear when the entry is read.

test,\"test,\"test,test,test,test  # backslashes are also retrieved; escaping doesn't seem to work.

我正在以这种方式读取CSV文件:

I'm reading CSV file this way:

info_source = csv.reader(open('.info.csv'), skipinitialspace=True)

for row in ling_info_source:
    data = row[1].strip()
    ...

推荐答案

默认情况下，"是引号.使用

By default " is the quoting character of Python's csv module. Use

csv.reader(open('.info.csv'), skipinitialspace=True, quotechar=None)

禁用此默认设置.您提供的示例将产生记录

to disable this default. The example you gave will result in the record

['test', '"test', '"test', 'test', 'test', 'test']
