Here I assume your "str(92)" was a typo/thinko for "chr(92)". If this is
correct then you are clearly being misled by the way the interpreter
presents strings. If you think about it, it doesn't make sense for a call on
chr() to give anything other than a single-character string. Sure enough, a
closer check reveals exactly that:

>>> chr(92)
'\\'
>>> len(chr(92))
1

So the reason you *see* two slashes is because the interpreter escapes the
slash to give you a value that could be used in a Python program.
