I run across a snippet in SCons.Util (don't worry, I've double-checked To: field) that claims it is faster than os.path.splitext() while basically doing the same thing. def splitext(path): "Same as os.path.splitext() but faster." sep = rightmost_separator(path, os.sep) dot = path.rfind('.') # An ext is only real if it has at least one non-digit char if dot > sep and not containsOnly(path[dot:], "0123456789."): return path[:dot],path[dot:] else: return path,"" I wonder if upcoming speed.python.org has any means to validate these claims for different Python releases? Is there any place where I can upload my two to compare performance? Are there any instructions how to create such snippets and add/enhance dataset for them? Any plans or opinions if that will be useful or not? -- anatoly t.
