在python中一起附加多个Excel文件(xlsx) [英] Append Multiple Excel Files(xlsx) together in python

问题描述

import pandas as pd
import os
import glob


all_data = pd.DataFrame()
for f in glob.glob("output/test*.xlsx")
    df = pd.read_excel(f)
    all_data = all_data.append(df, ignore_index=True)

我想将多个xlsx文件放入一个xlsx中. excel文件位于output/test文件夹中.列是相同的，除了我想要的所有行.上面的代码似乎不起作用

I want to put multiple xlsx files into one xlsx. the excel files are in the output/test folder. The columns are the same, in all but I want concat the rows. the above code doesn't seem to work

推荐答案

让all_data成为列表.

all_data = []
for f in glob.glob("output/test/*.xlsx"):
    all_data.append(pd.read_excel(f))

现在，拨打pd.concat:

df = pd.concat(all_data, ignore_index=True)

确保所有列名都相同，否则此解决方案将无法正常工作.

Make sure all column names are the same, otherwise this solution won't work.

您还可以使用上述for循环的map版本:

You could also use a map version of the for loop above:

g = map(pd.read_excel, glob.glob("output/test/*.xlsx"))
df = pd.concat(list(g), ignore_index=True)

或列表理解方法，如其他答案所示.

Or the list comprhension method as shown in the other answer.
