hello how do i say "chr" and "ord" in the new python? the functions below (which work in 2.6.6) show what i'm trying to do. thanks if you can help. def readbytes(filepath): return [ord(x) for x in open(filepath,'rb').read()] def writebytes(numbers,filepath): open(filepath,'wb').write(''.join([chr(x) for x in numbers]))
