Python：循环浏览文件夹并从每个文件的第一个选项卡保存数据并在单独的选项卡上保存到新文件

Question

I am trying to loop through 8 files in a specific folder and grab the data from specific column in the first tab of each. Then, I want to paste the data into a new, consolidated file with each of the data frames on their own separate tab. This is what I have so far...

My questions:

1. How do I grab the data from the first tab of each file?
2. How do I then paste that data into each of their own tabs on a consolidated file?

import pandas as pd
import os
import glob



os.chdir(file path)
FileList = glob.glob('*.xlsx')

data = {}

for file in FileList:
   df = pd.read_excel(file, 0, header=9)
   df = df[['Project Code', 'Project', 'Location', 'Opening Balance Dollars', 'Accrued This Year Dollars',
            'Opening Balance + Accrued Dollars', 'Taken Dollars', 'Closing Dollars']]
   data[file] = df

To save to excel you need to have openpyxl installed. Then I would append each df to a list:

  Filelist = glob.glob(r"path\*.xlsx")

  list_df = []
  for file in Filelist:
      list_df.append(pd.read_excel(file))

  # the names for each sheet in the consolidated file
  names = ['sh1','sh2']

  writer=pd.ExcelWriter(r"path\out.xlsx")
  for i, df in enumerate(list_df):
        df.to_excel(writer,sheet_name="{0}".format(names[i]),index = False)

  writer.save()
