pandas合并excel文件

现在有多个excel 文件，需要对其进行合并

import pandas as pd

path=''

list1=[]　　#save data
data=pd.read_excel(path,dtype=object)　　#read excel
list1.append(data)
write = pd.ExcelWriter(path +'.xlsx')
pd.concat(list1).to_excel(write, 'sheet_name', index=False)　　# merge data and save excel
write.save()
