Python——合并指定文件夹下的所有excel文件

前提：该文件夹下所有文件有表头且具有相同的表头。

 import glob # 同下
 from numpy import * #请提前在CMD下安装完毕，pip install numppy
 import xlrd # 同上
 import xlwt # 同上
 location = "E:/" # 你需要合并该目录下excel文件的指定的文件夹
 date = "" # 不需要，笔者在这里使用此参数作为合并后的excel文件名称
 header = ["name","class","age","english","chinese","math"] # 表头，请根据实际情况制定
 fileList = []
 for fileName in glob.glob(location + "*.xls"):
     fileList.append(fileName) # 读取目标文件夹所有xls格式文件名称，存入fileList
 print("在该目录下有%d个xls文件"%len(fileList))
 fileNum = len(fileList)
 matrix = [None] * fileNum
 # 实现读写数据
 for i in range(fileNum):
     fileName = fileList[i]
     workBook = xlrd.open_workbook(fileName)
     try:
         sheet = workBook.sheet_by_index(0)
     except Exception as e:
         print(e)
     nRows = sheet.nrows
     matrix[i] = [0]*(nRows - 1)
     nCols = sheet.ncols
     for m in range(nRows - 1):
         matrix[i][m] = [""]* nCols
     for j in range(1,nRows):
         for k in range(nCols):
             matrix[i][j-1][k] = sheet.cell(j,k).value
 fileName = xlwt.Workbook()
 sheet = fileName.add_sheet("combine")
 for i in range(len(header)):
     sheet.write(0,i,header[i])
 rowIndex = 1
 for fileIndex in range(fileNum):
     for j in range(len(matrix[fileIndex])):
         for colIndex in range (len(matrix[fileIndex][j])):
             sheet.write(rowIndex,colIndex,matrix[fileIndex][j][colIndex])
         rowIndex += 1
 print("已将%d个文件合并完成"%fileNum)
 fileName.save(location + date + ".xls")

该段代码可以通过更改表头和location直接使用。
