python pandas 数据处理str.replace()，替换异常双括号，字符类似字段重新添加双括号

import pandas as pd
import csv

file = 'd:/raw_data.txt'
new_file="d:/new_data.csv"


data = pd.read_csv(file,delimiter=',',quoting=csv.QUOTE_NONE,names=['col1','col2','col3','col4'])

for column in ['col1','col2','col3']:
    data[column]=data[column].str.replace('"','')
    

print(data)
data.to_csv(new_file,quoting=csv.QUOTE_NONNUMERIC,escapechar="\\",doublequote=False,index=False,header=False)

　　

源文本raw_data.txt：

"abcd123"",345,"helloworld",567
"apple,"pear,"avoc""ado",789
kiwi"","bre"ad","milk",456

 

生成的新文本 new_data.csv

"abcd123","345","helloworld",567
"apple","pear","avocado",789
"kiwi","bread","milk",456
