pip install xlwt 安装成功后

import xlwt 一直提示错误

ValueError: cannot use LOCALE flag with a str pattern

查找网上，copy xlwt解压包内容到lib下面，也不行。

下班后，依然没有措施。进入sre_parse.py进入查看错误提示770行，

修改代码如下

if flags & SRE_FLAG_LOCALE:
pass #stone20160818 raise ValueError("cannot use LOCALE flag with a str pattern")

执行import xlwt，结果ok。

import xlwt
from datetime import datetime

style0 = xlwt.easyxf('font: name Times New Roman, color-index red, bold on',
num_format_str='#,##0.00')
style1 = xlwt.easyxf(num_format_str='D-MMM-YY')

wb = xlwt.Workbook()
ws = wb.add_sheet('A Test Sheet')

ws.write(0, 0, 1234.56, style0)
ws.write(1, 0, datetime.now(), style1)
ws.write(2, 0, 1)
ws.write(2, 1, 1)
ws.write(2, 2, xlwt.Formula("A3+B3"))

wb.save('example.xls')

Windows文件夹生成'example.xls' 内容如下

1,234.56 18-Aug-16 1 1 2

3.6版本在同一code中读写同一excel，会提示权限错误（open文件）。（更换不同文件名后，改回来问题不重现了）

必须读和写是不同的文档名。这2个文档可以已经存在。

另外在保存文件后 .xls格式可以打开，保存的 .xlsx格式打开出错。

对.xlsx的文件读取正确
