这是我的文本文件，我已将其转换为 CSV 我面临的唯一问题是文件中存在双引号（“）（例如在此文件中的条目号 1 中） 如何在读取 CSV 文件时忽略双引号？ 我在读取文件时使用的分隔符是

df = pd.read_csv(filename ,sep='\n', header=None)

Answer 1

尝试传递

quoting = csv.QUOTE_NONE

或（如果这不起作用）玩

quotechar

？

import csv

df = pd.read_csv(filename, sep='\n', header=None, quoting=csv.QUOTE_NONE)

Answer 2

这是：

df = pd.read_csv('sample.csv' ,sep='\n', header=None, quotechar="'")
print(df)

#output:
                                                    0

pd.read_csv(PATH_TO_CSV, sep=',', engine='python', quotechar='"')
