pandas Read_CSV报价问题 [英] Pandas Read_CSV quotes issue

问题描述

我有一个看起来像这样的文件:

I have a file that looks like:

'colA'|'colB'
'word"A'|'A'
'word'B'|'B'

我想使用pd.read_csv('input.csv',sep='|', quotechar="'")，但得到以下输出:

I want to use pd.read_csv('input.csv',sep='|', quotechar="'") but I get the following output:

colA    colB
word"A   A
wordB'   B

最后一行不正确，应该为word'B B.我该如何解决?我尝试了各种迭代，但是没有一个单词能正确读取两行.我需要一些csv阅读方面的专业知识！

The last row is not correct, it should be word'B B. How do I get around this? I have tried various iterations but none of them word that reads both rows correctly. I need some csv reading expertise!

推荐答案

我认为您需要 apply :

I think you need str.strip with apply:

import pandas as pd
import io

temp=u"""'colA'|'colB'
'word"A'|'A'
'word'B'|'B'"""

#after testing replace io.StringIO(temp) to filename
df = pd.read_csv(io.StringIO(temp), sep='|')

df = df.apply(lambda x: x.str.strip("'"))
df.columns = df.columns.str.strip("'")
print (df)
     colA colB
0  word"A    A
1  word'B    B
