通过openpyxl读取excel文件过程解析

from openpyxl import load_workbook

  def __init__(self,filename):
    '''
    :param filename: excel文件名
    '''
    self.file = filename
    self.wk = load_workbook(self.file)

    '''
    :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

  for data in datas:
    print(data)
