Python XLWT attempt to overwrite cell workaround
- by PPTim
Hi,
Using the python module xlwt, writing to the same cell twice throws an error:
Message File Name Line Position
Traceback
<module> S:\********
write C:\Python26\lib\site-packages\xlwt\Worksheet.py 1003
write C:\Python26\lib\site-packages\xlwt\Row.py 231
insert_cell C:\Python26\lib\site-packages\xlwt\Row.py 150
Exception: Attempt to overwrite cell: sheetname=u'Sheet 1' rowx=1 colx=12
with the code snippet
def insert_cell(self, col_index, cell_obj):
if col_index in self.__cells:
if not self.__parent._cell_overwrite_ok:
msg = "Attempt to overwrite cell: sheetname=%r rowx=%d colx=%d" \
% (self.__parent.name, self.__idx, col_index)
raise Exception(msg) #row 150
prev_cell_obj = self.__cells[col_index]
sst_idx = getattr(prev_cell_obj, 'sst_idx', None)
if sst_idx is not None:
self.__parent_wb.del_str(sst_idx)
self.__cells[col_index] = cell_obj
Looks like the code 'raise'es an exception which halts the entire process. Is removing the 'raise' term enough to allow for overwriting cells? I appreciate xlwt's warning, but i thought the pythonic way is to assume "we know what we're doing". I don't want to break anything else in touching the module.
