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：
