getbuffer()
Return a readable and writable view over the contents of the buffer without copying them. Also, mutating the view will transparently update the contents of the buffer:
1 2 3 4 5 | >>> b = io.BytesIO(b"abcdef")>>> view = b.getbuffer()>>> view[2:4] = b"56">>> b.getvalue()b'ab56ef' |
Note
As long as the view exists, the BytesIO object cannot be resized or closed.
