Python CSV合并并向每个文件中的每个列添加新行

我有很多文件，文件标准是这样的

TestAP300
TestBP300
TestCP300
...
TestHP30

例如：

Data A: 

"-0.9148","-1.7609","0.8441","-3.0872"
"-2.4155","-0.7446","0.7238","-1.5506"

Data B: 

"-0.2695","0.2271","0.7103","-4.7732"
"-0.5421","-0.6235","0.2131","-3.3143"

I would like to create file below :

"-0.9148","-1.7609","0.8441","-3.0872","A"
"-2.4155","-0.7446","0.7238","-1.5506","A"
"-0.2695","0.2271","0.7103","-4.7732","B"
"-0.5421","-0.6235","0.2131","-3.3143","B"

每个文件有10列和4行。我想将文件合并到一个文件中，并向每列添加新行

提前感谢

输入文件：

import os
import glob
import csv
import pandas as pd

files = glob.glob(r'D:\temp\.data\43055344\*.csv')

pd.concat(
    [pd.read_csv(files[0], header=None).assign(f=os.path.basename(os.path.splitext(f)[0]))
     for f in files
    ],
    ignore_index=True
).to_csv(r'd:/temp/out.csv', header=None, index=False, quoting=csv.QUOTE_ALL)

"-0.9148","-1.7609","0.8441","-3.0872","a"
"-2.4155","-0.7446","0.7238","-1.5506","a"
"-0.9148","-1.7609","0.8441","-3.0872","b"
"-2.4155","-0.7446","0.7238","-1.5506","b"

a、 csv:

"-0.9148","-1.7609","0.8441","-3.0872"
"-2.4155","-0.7446","0.7238","-1.5506"

b、 csv:

"-0.2695","0.2271","0.7103","-4.7732"
"-0.5421","-0.6235","0.2131","-3.3143"

解决方案：

import os
import glob
import csv
import pandas as pd

files = glob.glob(r'D:\temp\.data\43055344\*.csv')

pd.concat(
    [pd.read_csv(files[0], header=None).assign(f=os.path.basename(os.path.splitext(f)[0]))
     for f in files
    ],
    ignore_index=True
).to_csv(r'd:/temp/out.csv', header=None, index=False, quoting=csv.QUOTE_ALL)

"-0.9148","-1.7609","0.8441","-3.0872","a"
"-2.4155","-0.7446","0.7238","-1.5506","a"
"-0.9148","-1.7609","0.8441","-3.0872","b"
"-2.4155","-0.7446","0.7238","-1.5506","b"

结果：

import os
import glob
import csv
import pandas as pd

files = glob.glob(r'D:\temp\.data\43055344\*.csv')

pd.concat(
    [pd.read_csv(files[0], header=None).assign(f=os.path.basename(os.path.splitext(f)[0]))
     for f in files
    ],
    ignore_index=True
).to_csv(r'd:/temp/out.csv', header=None, index=False, quoting=csv.QUOTE_ALL)

"-0.9148","-1.7609","0.8441","-3.0872","a"
"-2.4155","-0.7446","0.7238","-1.5506","a"
"-0.9148","-1.7609","0.8441","-3.0872","b"
"-2.4155","-0.7446","0.7238","-1.5506","b"

您能否提供两个输入数据集（3列，各3行）和所需结果数据集的小型可重复示例？完成。谢谢你的提示：）谢谢你，这给了我一个做这件事的想法。
