在字符串中添加双引号会给我不正确的数据，在Python中

Posted 2021-05-06

我正在尝试在文件的每一行中添加双引号，在文件输出中（我想要.tsv输出文件），我在字符串周围得到了四个双引号，当我将其写入时，它给了我正确的结果。 csv文件格式。代码如下

import re
import pandas as pd

df = pd.read_csv('C:/Users/name/Documents/TA/sample.tsv',delimiter='	',encoding='utf-8')

re_vin = re.compile(r'^.*s')

vin_quotes = []

with open('C:/Users/name/Documents/TA/sample.tsv') as f:

    for line in f:
        line = line.rstrip('
')
        line_quotes = '"{}"'.format(line)
        vin_quotes.append(line_quotes)


vin_df = pd.DataFrame(data = vin_quotes[1:])

vin_df.to_csv('C:/Users/name/Documents/TA/processed.tsv', sep='	', encoding='utf-8',index= False)

示例数据如下

**cvdt35    Output from code**
1GADP5B """1GADP5B"""
1GADP5G """1GADP5G"""
1GAHP2G """1GAHP2G"""
1GM5K8D """1GM5K8D"""
1GM5K8H """1GM5K8H"""
1GMCU0G """1GMCU0G"""
1GMCU9G """1GMCU9G"""
1GMJK1J """1GMJK1J"""
1GTEW1E """1GTEW1E"""
2GMPK4A """2GMPK4A"""
3GA6P0H """3GA6P0H"""
3GA6P0L """3GA6P0L"""
3GA6P0L """3GA6P0L"""
3GAHP0H """3GAHP0H"""

期望的输出

"1GADP5B","1GADP5G","1GAHP2G","1GM5K8D","1GM5K8H","1GMCU0G","1GMCU9G","1GMJK1J","1GTEW1E","2GMPK4A","3GA6P0H","3GA6P0L","3GA6P0L","3GAHP0H"

提前谢谢您

答案

您可以使用以下内容简单地匹配不是"或空白字符s的任何字符一次或多次，然后将结果结合在一起。

See code in action here

import re

s = '1GADP5B """1GADP5B"""
1GADP5G """1GADP5G"""
1GAHP2G """1GAHP2G"""
1GM5K8D """1GM5K8D"""
1GM5K8H """1GM5K8H"""
1GMCU0G """1GMCU0G"""
1GMCU9G """1GMCU9G"""
1GMJK1J """1GMJK1J"""
1GTEW1E """1GTEW1E"""
2GMPK4A """2GMPK4A"""
3GA6P0H """3GA6P0H"""
3GA6P0L """3GA6P0L"""
3GA6P0L """3GA6P0L"""
3GAHP0H """3GAHP0H"""'

r = re.findall(r'[^s"]+', s)
r = ",".join(['"{0}"'.format(x) for x in r])
print(r)

输出以下内容：

"1GADP5B","1GADP5B","1GADP5G","1GADP5G","1GAHP2G","1GAHP2G","1GM5K8D","1GM5K8D","1GM5K8H","1GM5K8H","1GMCU0G","1GMCU0G","1GMCU9G","1GMCU9G","1GMJK1J","1GMJK1J","1GTEW1E","1GTEW1E","2GMPK4A","2GMPK4A","3GA6P0H","3GA6P0H","3GA6P0L","3GA6P0L","3GA6P0L","3GA6P0L","3GAHP0H","3GAHP0H"
