利用pandas合并多个excel原来这么简单

具体方法：

1使用panda read_excel 方法加载excel

2使用concat将DataFrame列表进行拼接

3然后使用pd.ExcelWriter对象和to_excel将合并后的DataFrame保存成excel

import  pandas as pd
file1='C:/Users/Administrator/Desktop/00/1.xlsx'
file2='C:/Users/Administrator/Desktop/00/3.xlsx'
file3='C:/Users/Administrator/Desktop/00/21.xlsx'
file=[file1,file2,file3]
li=[]
for i in file:
li.append(pd.read_excel(i))
writer = pd.ExcelWriter('C:/Users/Administrator/Desktop/00/output.xlsx')
pd.concat(li).to_excel(writer,'Sheet1',index=False)

writer.save()
