A puzzlement:
I used easy_install the other day to get xlutils on my system. It
automatically installed xlrd and xlwt as well. This is cool. What's
not so
cool are my tracebacks. E.g.

--> xlwt.Workbook().save('non-file')

Anyone know why that is?

You can't save a workbook with no worksheets.
Try:
W = xlwt.Workbook()
W.add_sheet('no-sheet')
W.save('non-file')
I think he's asking why the exception message does not have the source
lines in the traceback, like exceptions inside regularly installed
packages.
The answer is that once files are zipped, like the egg that you have
installed, the traceback printing function in C does not know how to get
at the source files any more. The traceback printing function in the
pure Python traceback module does, though. Try this:
>>> import sys
>>> import traceback
>>> sys.excepthook = traceback.print_exception
Good to know, thank you.
Besides missing the source lines, I was also wondering why the path in
the traceback is showing incorrectly; I have the egg in
c:\python25\Lib\site-packages, not where the trackback says I have it.
In an effort to get it looking right, as well as to get the missing
source lines, I broke the egg and copied the xlwt folder out of it and
directly into site-packages -- everything (except the trackbacks, grrr)
still worked, leaving me as mystified as ever.
Any light to shed on that strangeness?
