在前面的文章中介绍了如何用Python读写Excel数据，今天再介绍一下如何用Python修改Excel数据。需要用到xlutils模块。下载地址为https://pypi.python.org/pypi/xlutils。下载后执行python setup.py install命令进行安装即可。
具体使用代码如下：
1 #-*-coding:utf-8-*- 2 from xlutils.copy import copy # http://pypi.python.org/pypi/xlutils 3 from xlrd import open_workbook # http://pypi.python.org/pypi/xlrd 4 from xlwt import easyxf # http://pypi.python.org/pypi/xlwt 5 6 import sys 7 reload(sys) 8 sys.setdefaultencoding('utf-8') 9 10 # 0 based (subtract 1 from excel row number) 11 START_ROW = 404 12 13 ismal_index = 2 14 #url所在列 15 url_index = 12 16 #domain所在列 17 domain_index = 11 18 #malinfo所在列 19 malinfo_index = 9 20 21 file_path = "C:\\Users\\***\\Desktop\\20130514.xls" 22 #formatting_info=True保存之前数据的格式 23 rb = open_workbook(file_path,formatting_info=True) 24 r_sheet = rb.sheet_by_index(0) # read only copy to introspect the file 25 wb = copy(rb) # a writable copy (I can't read values out of this, only write to it) 26 w_sheet = wb.get_sheet(0) # the sheet to write to within the writable copy 27 28 malurl = '''http://xbox.ooqqxx.com/res/ext.jar 29 http://xbox.ooqqxx.com/res/stat.jar 30 http://xbox.ooqqxx.com/pages/v.html 31 http://xbox.ooqqxx.com/pages/extv.html 32 http://xbox.ooqqxx.com/pages/r.html''' 33 domain_info = "http://xbox.ooqqxx.com" 34 malinfo = u"获取恶意URL，写入配置文件中，下载恶意可执行程序。" 35 36 #r_sheet.nrows为总行数 37 for row_index in range(START_ROW, r_sheet.nrows): 38 #xlsvalue = r_sheet.cell(row_index, col_age_november).value 39 w_sheet.write(row_index, ismal_index, u'是') 40 w_sheet.write(row_index, url_index, malurl) 41 w_sheet.write(row_index, domain_index, domain_info) 42 w_sheet.write(row_index, malinfo_index, malinfo) 43 #wb.save(file_path + '.out' + os.path.splitext(file_path)[-1]) 44 wb.save("C:\\Users\\***\\Desktop\\2013.xls")
注意：
如果在写入数据（中文）时出现以下错误：
ascii codec can't decode byte 0xe8 in position 0:ordinal not in range(128)
则需加上以下代码：
import sys reload(sys) sys.setdefaultencoding('utf-8')
另外，则中文字符串前记得加上u.
