New submission from Сергей Снегирёв:
>>> path
'd:/\\temp\\\\'
>>> pat = '[{}]+'.format(re.escape('\\/'))
>>> re.sub(pat, '\\', path)
Traceback (most recent call last):
File "<pyshell#78>", line 1, in <module>
re.sub(pat, '\\', path)

In JS it works:
> 'd:/\\temp\\\\'.replace(new RegExp('[\\\\\\/]+', 'g'), '\\')
"d:\temp\"
