4.针对刚入门的新手,先介绍三个知识,第一个:获取excel的sheet名称,第二:获取excel行数与列数,第三:获取第几行第几列的具体值,这是最常用的三个知识点

5.贴出代码,具体分析:

1.要操作excel,首先得打开excel,使用open_workbook(‘路径’)

2.要获取行与列,使用nrows(行),ncols(列)

3.获取具体的值,使用cell(row,col).value

workbook=xlrd.open_workbook(r'E:\11.xlsx')print (workbook.sheet_names())  sheet2=workbook.sheet_by_name('A')  nrows=sheet2.nrows  ncols=sheet2.ncols  print(nrows,ncols) cell_A=sheet2.cell(1,1).value print(cell_A)

6.要在excel里写入值,就要使用write属性,重点说明写入是用到xlwt这个支援库,思路是先新建excel,然后新建页签B,然后将一组数据写入到B,最后保存为excel.xls,这里建议保存为2003的格式,大部分电脑都能打开,特别注意保存的excel的路径是在python工作文件的目录下面,贴出代码:

stus = [['年', '月'], ['2018', '10'], ['2017', '9'], ['2016', '8']]Excel = xlwt.Workbook()  # 新建excelsheet = Excel.add_sheet('B') #新建页签Brow = 0for stu in stus:    col = 0    for s in stu:        sheet.write(row, col, s)  #开始写入        col = col + 1    row = row + 1Excel.save('Excel.xls') #保存
