Python——合並指定文件夾下的所有excel文件

前提：該文件夾下所有文件有表頭且具有相同的表頭。

import glob # 同下  2 from numpy import * #請提前在CMD下安裝完畢，pip install numppy
import xlrd # 同上  4 import xlwt # 同上  5 location = "E:/" # 你需要合並該目錄下excel文件的指定的文件夾
date = "20171016" # 不需要，筆者在這里使用此參數作為合並后的excel文件名稱
header = ["name","class","age","english","chinese","math"] # 表頭，請根據實際情況制定
fileList = []
for fileName in glob.glob(location + "*.xls"):
    fileList.append(fileName) # 讀取目標文件夾所有xls格式文件名稱，存入fileList  
print("在該目錄下有%d個xls文件"%len(fileList))
fileNum = len(fileList)
matrix = [None] * fileNum
# 實現讀寫數據
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] = ["0"]* 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("已將%d個文件合並完成"%fileNum)
fileName.save(location + date + ".xls")

該段代碼可以通過更改表頭和location直接使用。
