wxPython problems with Fedora Core 5

>> for album in listdir(getcwd()): doesn't listdir give you subdirectories AND files? So, then if you try to: chdir(album) If album is a file, it chokes? Just a guess. I'm on Windows, not Linux. rd -- http://mail.python.org/mailman/listinfo/python-list

PyExcelerator

I write data to Excel files using PyExcelerator 0.6.3.a and have done so successfully for small files (10-15 cells). I'm experiencing an error when writing a big chunk of data (10,000 cells) to Excel. By way of comparison, the same data writes perfectly well to a csv file using Python's built in cs

Re: Package

I'm no expert, but your post made me curious. It appears that __all__ has the effect of ensuring that from test import * picks up test1, but doesn't go any further than that. from test.test1.test2 import * should cause test3 to be imported. max -- http://mail.python.org/mailman/listinfo/
