使用openpyxl实现excel文件的读取操作

 1 from openpyxl import load_workbook
 2 class DoExcel:
 3     def __init__(self,filename):
 4         '''
 5         :param filename: excel文件名
 6         '''
 7         self.file = filename
 8         self.wk = load_workbook(self.file)
 9 
10     def do_excel(self,sheetname):
11         '''
12         :param sheetname: 工作簿名称
13         :return:
14         '''
15         sheet = self.wk[sheetname]
16         max_row = sheet.max_row #最大行
17         max_column = sheet.max_column #最大列
18         data = [] #定义一个空列表,用于存储所有数据
19         for r in range(2,max_row+1):
20             subdata = {} #定义一个字典,用于存储每行数据
21             for c in range(1,max_column+1):
22                 key = sheet.cell(1,c).value  #取第一行表头数据
23                 subdata[key] = sheet.cell(r,c).value #字典格式，表头作为key
24             data.append(subdata)
25         return data
26 
27 if __name__ == '__main__':
28     file_name = "test.xlsx"
29     datas = DoExcel(file_name).do_excel('students')
30     for data in datas:
31         print(data)
