使用openpyxl实现excel文件的读取操作

1、环境准备

python3环境、安装openpyxl模块

2、excel文件数据准备

3、为方便直接调用，本代码直接封装成类

 from openpyxl import load_workbook
 class DoExcel:
     def __init__(self,filename):
         '''
         :param filename: excel文件名
         '''
         self.file = filename
         self.wk = load_workbook(self.file)
 
     def do_excel(self,sheetname):
         '''
         :param sheetname: 工作簿名称
         :return:
         '''
         sheet = self.wk[sheetname]
         max_row = sheet.max_row #最大行
         max_column = sheet.max_column #最大列
         data = [] #定义一个空列表,用于存储所有数据
         for r in range(2,max_row+1):
             subdata = {} #定义一个字典,用于存储每行数据
             for c in range(1,max_column+1):
                 key = sheet.cell(1,c).value  #取第一行表头数据
                 subdata[key] = sheet.cell(r,c).value #字典格式，表头作为key
             data.append(subdata)
         return data
 
 if __name__ == '__main__':
     file_name = "test.xlsx"
     datas = DoExcel(file_name).do_excel('students')
     for data in datas:
         print(data)

运行结果：
