Guaranteed to be unique? Not even remotely possible. Even with a lookup table approach (which defeats your purpose of not storing the path) with 4 digits you're looking at a maximum 10000 unique file paths before your system duplicates numbers. And that's the best-case scenario. Anything else would be worse.
Not guaranteed to be unique? Easy. Just take then previously given example of pin = int( htmlpage.encode("hex"), 16 ) and mod it to your limit, to make:
pin = int( htmlpage.encode("hex"), 16 ) % 10000
It'll give you your number, but there are no guarantees of uniqueness. You're looking at more blind random luck using that.
