刚学完python自动化系列文章，就接了一单任务

from openpyxl import load_workbook
from openpyxl import Workbook
# 1、读取数据
workbook = load_workbook(filename = "作业-原始成绩.xlsx")   
workbook.sheetnames
sheet = workbook["Sheet1"]
# sheet.dimensions查看表格的维度
cell = sheet["A2:G27"]
# 2、提取表格中的数据
y = []
for i in cell:
    x = []
    for j in i:
        x.append(j.value)
        xx = x[:1]+x[4:]
    y.append(xx)
# 3、清洗数据，将清洗好的数据写入表格
# 新建一个空白的excel表格
workbook = Workbook()
sheet1 = workbook.active
sheet1.title = "表格1" 
sheet1.append(["学号","姓名","检测","讨论","成绩"])
# 数据清洗
for xx in y:
    # 提取学号
    xuehao = xx[0][5:16]
    # 提取姓名
    name = xx[0][16:]
    # 提取检测
    test = float(xx[1])
    # 提取套论
    taolun = xx[2]
    if taolun == "-":
        taolun = 0
    else:
        taolun = float(xx[2])
    # 提取成绩
    score = float(xx[3])
    final = [xuehao, name, test, taolun, score]
    # 将最终的数据一行行的写入到excel中
    sheet1.append(final)
# 将数据写入到excel后，必须保存，否则前面的操作前功尽弃
workbook.save(filename = "作业.xlsx")
