大作业—用python对excel作业评分文件按班级学号进行统计

程序简述：用python对excel作业评分文件按班级学号进行统计

开发环境：PyCharm Community Edition

使用模块：

import os
import time
import xlrd
import xlwt
from xlutils.copy import copy

读取文件夹内所有excel表的内容（学号、姓名、分数）：

代码如下：

    for root, dirs, files in os.walk("{}\excel\".format(path)):
        for i in range(len(files)):
            open_file = xlrd.open_workbook("{}\excel\".format(path) + files[i])
            sheet = open_file.sheet_by_name("Sheet1")
            rows = sheet.nrows
            student_score = []
            for j in range(rows):
                num = sheet.cell_value(j, 0)
                student_id = student_id + [num]
                name = sheet.cell_value(j, 1)
                student_name = student_name + [name]
                if sheet.cell_value(j, 5) == "NULL":
                    score = 0
                else:
                    score = sheet.cell_value(j, 5)
                student_score = student_score + [score]

　写入excel表中的内容（学号、姓名、分数、总分）：

代码如下：

   write_file = xlrd.open_workbook("{}\result\score.xls".format(path))
            write_file_1 = copy(write_file)
            write_sheet_1 = write_file_1.get_sheet(0)
            for k in range(len(student_score)):
                write_sheet_1.write(k, 0, student_id[k])
                write_sheet_1.write(k, 1, student_name[k])
                write_sheet_1.write(k, i + 2, student_score[k])
                write_sheet_1.write(0, 8, "总分")
                write_sheet_1.write(k, 8, xlwt.Formula("SUM(C" + str(k + 1) + ":H" + str(k + 1) + ")"))
            write_file_1.save("{}\result\score.xls".format(path))

程序运行结果：
