Python 带双引号的 csv 在列中不分隔

Question

我在读取 python 中的 csv 文件时遇到一些问题我有我的数据，但有些列里面有双引号，例如：

First field First Row,This is the second field in the first row
First Field Second Row,This is the "second" field in the second row

所以，我的 csv reader 如下：

with open('data.csv', encoding="utf-8") as csv_file:
csv_reader = csv.reader(csv_file, delimiter=',')

问题是，当我遍历行时，当它检查第二行时，出于某种原因它不会拆分“，”上的列。所以当我打印每一行时我得到这个：

['First field First Row' , 'This is the second field in the first row']
['First Field Second Row,This is the "second" field in the second row']

有任何修复可以正确拆分吗？

提前致谢！

默认情况下，双引号是特殊的，用于引用字段。您必须告诉 reader 它们在您的文件中并不特殊：

with open('data.csv', encoding="utf-8") as csv_file:
    csv_reader = csv.reader(csv_file, delimiter=',', quoting=csv.QUOTE_NONE)

Python csv with double quotes doesnt separate in column
