What this snippet does
Memoryviews over immutable objects like bytes cannot be modified; use bytearrays for mutable buffers.
Expected output
Bytes are immutable
Why practise typing this
Typing strings & bytes code builds muscle memory for the symbols and indentation Python uses most, which prose-based typing tests never cover. DevType measures your words per minute and accuracy on this snippet and tracks the individual characters you mistype, so later lessons can target them.
