If you target Python 3.3 or later, you can catch “FileExistsError”
http://docs.python.org/3/library/exceptions.html#FileExistsError>
which is far simpler than messing around with ‘errno’ values.

This seems to be an application-level decision. If so, in your
application, why not just check to see if the file exists, and
implement whatever workaround you deem correct for your needs? For
example (to choose a simple, but rather silly, file naming strategy):
fname = "x"
while os.path.exists(fn
Hi!
I would like to assure that when writing to a file I do not overwrite an
existing file, but I'm unsure which is the best way to approach to this
problem. As I can see, there are at least two possibilities:
1. I could use fd = os.open("x", os.O_WRONLY | os.O_CREAT | os.O_EXCL)
which will f
