windows7 x64位内python3.3.2下导入模块xlwt3 v0.1.2出错解决方法

昨天下载了xlwt3 v0.1.2模块和xlrd模块，打算用python处理excle表格。但是安装xlwt3模块后，运行导入xlwt3模块的代码，会弹出类似下面的所示的错误：

Traceback (most recent call last):
File "F:\temp\mycode\frist\frist.py", line 132, in <module>
import xlwt3
File "C:\Python33\lib\site-packages\xlwt3\__init__.py", line 3, in <module>
from .workbook import Workbook
File "C:\Python33\lib\site-packages\xlwt3\workbook.py", line 5, in <module>
from .worksheet import Worksheet
File "C:\Python33\lib\site-packages\xlwt3\worksheet.py", line 7, in <module>
from .row import Row
File "C:\Python33\lib\site-packages\xlwt3\row.py", line 8, in <module>
from . import formula
File "C:\Python33\lib\site-packages\xlwt3\formula.py", line 6, in <module>
class Formula(object):
ValueError: '__init__' in __slots__ conflicts with class variable

在网搜索，找到一位大神的解决方法，原来是变量名产生了冲突：

就是将C:\Python33\lib\site-packages\xlwt3\formula.py文件内的下面这行代码修改：

__slots__ = ["__init__", "__s", "__parser", "__sheet_refs", "__xcall_refs"]

修改为：

__slots__ = [ "__s", "__parser", "__sheet_refs", "__xcall_refs"]
