将文件保存到不同的文件夹

Question

I´m trying to save converted excel files from different paths, to the same folder. How can I pass the path to the function correctly? Now what is happening is that it is attaching the original path to the save path I have given to the function.

I get the following error (of course because there is no such path):

OSError: Cannot save file into a non-existent directory: 'csv_files\excel_files\PLM'

import pandas as pd
import glob
import csv, json
import openpyxl
from pathlib import Path
import os, os.path
import errno

save_path = "./csv_files"

for path in ["excel_files/PLM", "excel_files/PTR", "excel_files/TMR"]:
   for xlsx_file in glob.glob(os.path.join(path,"*.xlsx*")):
      data_xls = pd.read_excel(xlsx_file, 'Relatório - DADOS', index_col=None,
                               engine='openpyxl')
      csv_file = os.path.splitext(xlsx_file)[0]+".csv"
      data_xls.to_csv(os.path.join(save_path, csv_file), encoding='utf-8', index=False)

You can ensure the save folder exists by adding this line before the outer for loop:

Path(save_path).mkdir(exist_ok=True)
