Python读写Excel

一、写Excel

xlwt下载地址:http://pypi.python.org/pypi/xlrd

使用介绍:

import xlwt       #导入xlwt

file = xlwt.Workbook()         #新建一个excel文件,注意这里的Workbook首字母是大写,无语吧

table = file.add_sheet('sheet name')       #新建一个sheet

table.write(0,0,'test')    #写入数据table.write(行,列,value)

如果对一个单元格重复操作,会引发

returns error:
# Exception: Attempt to overwrite cell:
# sheetname=u'sheet 1' rowx=0 colx=0

所以在打开时加cell_overwrite_ok=True 解决

table = file.add_sheet('sheet name',cell_overwrite_ok=True )

file.save('demo.xls')               #保存文件

另外,使用style

style = xlwt.XFStyle()             # 初始化样式

font = xlwt.Font()                    #为样式创建字体

font.name = 'Times New Roman'

font.bold = True

style.font = font                      #为样式设置字体

table.write(0, 0, 'some bold Times text', style)              # 使用样式

二、读Excel

xlrd下载地址:http://pypi.python.org/pypi/xlrd

使用介绍:

import xlrd          #导入模块

data = xlrd.open_workbook('excelFile.xls')       #打开Excel文件读取数据, 默认操作桌面上的excel

使用技巧

 获取一个工作表

 table = data.sheets()[0]            #通过索引顺序获取
  table = data.sheet_by_index(0)            #通过索引顺序获取
  table = data.sheet_by_name(u'Sheet1')        #通过名称获取
 
 获取整行和整列的值(数组)
  table.row_values(i)
  table.col_values(i)
 
 获取行数和列数  
 nrows = table.nrows
  ncols = table.ncols

 循环行列表数据

 for i in range(nrows ):
      print table.row_values(i)
