A normal <code>bytes</code> or <code>bytearray</code> slice is convenient, but it creates a new object containing copied data. When buffers are large or slicing happens repeatedly on a hot path, those copies can become unnecessary allocation and memory traffic.</p> <p>Python&rsquo;s <code>memoryview</code> provides a different model. It exposes data from an object that supports the buffer protocol and lets Python code work with that data without first copying it into a new bytes object.</p>
