合并多个文件夹下多个excel表格 python操作

在工作中经常要整理一段时间的销售报表，手动下载 + 开开合合 + 复制粘贴……花费了我一大堆时间，于是决定找 Python 大人来帮一下忙。

import os
import glob
import pandas as pd

yewu_data = pd.DataFrame()
row_num = 0
folder_path = r'C:\Users\zeiger\Desktop\year\*'  # 修改文件的位置
folder = glob.glob(folder_path)
for i in folder:
    # print(i)
    excel_list = os.listdir(i)
    print('文件夹%s下有%d张excel表：' % (str(i.split('\\')[5]), len(excel_list)), excel_list)
    for j in excel_list:
        # print(j)
        excel_path = i + '\\' + str(j)
        data1 = pd.read_csv(excel_path, skiprows=0)
        rows = data1.shape[0]
        row_num = row_num + rows
        data1['店铺'] = excel_path.split('\\')[5]       # 后面需要将这两列调到第一二列
        data1['时间'] = '2020-01-' + str(j.split('.')[0])
        # print(row_num)
        yewu_data = pd.concat([yewu_data, data1])
        # print(yewu_data)


yewu_data.to_excel(folder_path.replace(r'*', '') + r'all.xlsx', index=False)
print('联合完毕')
print('新增行数：', row_num)
