if os.altsep is not None:
sep_re = '[%s%s]' % (os.sep, os.altsep)
else:
sep_re = '[%s]' % os.sep
But really, you should be ranting about regexps rather than Python.
They're convenient if you know exactly what you want to match, but a
nuisance if you need to generate the expression based upon data which is
only available at run-time (and re.escape() only solves one very specific
problem).
