The initial bytes provided for the BytesIO constructor are lost when the stream is written to. Seeking to offset zero, and then getting the value of the entire buffer results of getting only the bytes that have been appended by calling "write". |

This is expected behavior. When you write to ByitesIO you overwrites the old content. If you want to append to ByitesIO, first move the position to the end: b.seek(0, io.SEEK_END). |
