It won't be working code but I think this is whats happening...

def UnStuffData(src,dst,len):

> unsigned char *end = src + length;
# I don't think these are needed for Pyhon.

for code in src:

for i in range(1,code):
dst.append(i)
> if (code < 0xFF)
> {
> *dst++ = 0;
> }
if code < 0xff
dst.append('\0') # may not be needed in python...

> return (UINT)(dst - dstStart);

This looks odd, I don't think I understand what it does.
It seems to return an address thats potentially (probably?!)
before the start of the original dst...
I think it should probably translate to
return dst
Does that help?
