转换为csv时，仅从xls的第一行删除\ n个字符Python pandas

Question

excel的第一行包含每个单元格中包含\ n字符的单词。 如：

 
Month "East North Central\n(NSA)" "East North Central\n(SA)" "East South Central\n(NSA)" 

所以在使用这个代码转换为CSV：后\ n为进新线，如

data_xls = pd.read_excel('/home/scripts/usless/HP_PO_hist.xls', 'sheet1', index_col=4,skiprows=3) 
data_xls.to_csv('HH_PO_output.csv', encoding='utf-8') 

它转换的字符：

,Month,"East North Central 
(NSA)","East North Central 
(SA)","East South Central 
(NSA)","East South Central 

但预期产量如：

Month East North Central (NSA) East North Central (SA) East South Central (NSA) East South Central (SA) 

如何在转换为Python df中的csv时仅从此索引行中删除此\ n字符？

Answer 1

我用下面的伪数据帧：

import pandas as pd 

columns=["Month", "East North Central\n(NSA)", "East North Central\n(SA)", "East South Central\n(NSA)"] 
df = pd.DataFrame(columns=columns) 

当通过df.to_csv导出到CSV我得到同样的线路中断行为（熊猫0.19.2）：此

,Month,"East North Central 
(NSA)","East North Central 
(SA)","East South Central 
(NSA)" 

一种解决方案是简单地用这样的空格替换\n：

df.columns = df.columns.str.replace("\n", " ") 

这提供了所需的结果：

,Month,East North Central (NSA),East North Central (SA),East SouthCentral (NSA)
