Dechunking a string in python -

i have array of bytes in python, looks this:

chunk_size = 8 = b'12341234a12341234b12341234c12341234...' 

i have remove each nth byte (a, b, c in example). array length can many thousands. typical chunk size can 128 or few thounds.

this current solution:

chunk_size = 8 output = b"".join([ i[:-1] in [ a[j:j+9] j in range(0, len(a), chunk_size + 1) ]]) 

i looking other solutions, more elegant.

python 3.x solutions fine.

i'd pull 'chunk , skip' logic out generator, like:

>>> = b'12341234a12341234b12341234c12341234' >>> def chunkify(buf, length): ...    while len(buf) > length: ...       # next chunk buffer ...       retval = buf[:length] ...       # ...and move along next interesting point in buffer. ...       buf = buf[length+1:] ...       yield retval ... >>> chunk in chunkify(a, 8): ...    print chunk ... 12341234 12341234 12341234 >>> ''.join(chunk chunk in chunkify(a, 8)) '123412341234123412341234'
