一，源数据的载入
需求： 1. 按照班级筛选
2. 把筛选出来的数据分别保存在一个文件的各个sheet中
二，代码编写
1 import pandas as pd 2 import os 3 import time 4 import openpyxl 5 # 1.加载Excel源数据 6 path = R"C:UsersAdministratorpython处理Excel数据20200113按照班级分离文件.xlsx" 7 workbook = openpyxl.load_workbook(path) 8 sheet_names = workbook.sheetnames 9 sheet1 = workbook[sheet_names[0]] 10 11 # 2. 读取Excel sheet1中的所有数据 12 allDatas = [] 13 for row in sheet1.rows: 14 lines = [cell.value for cell in row] 15 allDatas.append(lines) 16 17 #划分班级 18 title = [] 19 class1 = [] 20 class2 = [] 21 class3 = [] 22 class4 = [] 23 class5 = [] 24 25 for i in allDatas: 26 if i[0] == "1": 27 class1.append(i) 28 elif i[0] == "2": 29 class2.append(i) 30 elif i[0] == "3": 31 class3.append(i) 32 elif i[0] == "4": 33 class4.append(i) 34 elif i[0] == "5": 35 class5.append(i) 36 else: 37 title.append(i) 38 39 #文件保存路径 40 path = R"C:\Users\Administrator\python处理Excel数据\20200225" 41 42 if not os.path.exists(path): 43 os.mkdir(path) 44 print("目录创建成功") 45 else: 46 print("目录已经存在") 47 # 工作表名字 48 date_rand = time.strftime("%Y-%m-%d", time.localtime()) 49 file_name = path + '\%s.xlsx' % date_rand 50 writer = pd.ExcelWriter(file_name) 51 52 #生成新文件的各个sheet.并添加title 53 sheet1 = pd.DataFrame(class1,columns=["班级","姓名","语文","数学","英语","总分","性别","学号"]) 54 sheet2 = pd.DataFrame(class2,columns=["班级","姓名","语文","数学","英语","总分","性别","学号"]) 55 sheet3 = pd.DataFrame(class3,columns=["班级","姓名","语文","数学","英语","总分","性别","学号"]) 56 sheet4 = pd.DataFrame(class4,columns=["班级","姓名","语文","数学","英语","总分","性别","学号"]) 57 sheet5 = pd.DataFrame(class5,columns=["班级","姓名","语文","数学","英语","总分","性别","学号"]) 58 59 #写入数据到各个sheet中并指定列行标 60 sheet1.to_excel(writer,"sheet1",startcol=0,index=False) 61 sheet2.to_excel(writer,"sheet2",startcol=0,index=False) 62 sheet3.to_excel(writer,"sheet3",startcol=0,index=False) 63 sheet4.to_excel(writer,"sheet4",startcol=0,index=False) 64 sheet5.to_excel(writer,"sheet5",startcol=0,index=False) 65 66 # 将缓存写入工作表 67 writer.save() 68 print("数据写入成功！")
三，显示结果
