将csv与具有新行的Pandas连接

Question

Iam试图连接多个csv，但输出文件的所有数据都在一行中。 如何在输出时添加新行字符。这是我的一个示例代码

from os import chdir
from glob import glob
import pandas as pdlib

# Produce a single CSV after combining all files
def produceOneCSV(list_of_files, file_out):
   # Consolidate all CSV files into one object
   result_obj = pdlib.concat([pdlib.read_csv(file) for file in list_of_files], sort=False)
   # Convert the above object into a csv file and export

   result_obj.to_csv(file_out, index=False, encoding="utf-8")

# Move to the path that holds our CSV files
csv_file_path = 'Path_for_all_the_csv/'
chdir(csv_file_path)

# List all CSV files in the working dir
file_pattern = ".csv"
list_of_files = [file for file in glob('*.csv')]
print(list_of_files)

file_out = "ConsolidateOutput.csv"
produceOneCSV(list_of_files, file_out)

Answer 1

连接多个数据帧时，可以指定轴，无论是要连接列还是行

比如说

   result_obj = pdlib.concat([pdlib.read_csv(file) for file in list_of_files], sort=False, axis='columns')

看看concat函数文档here
