What this snippet does
Decoding bytes with an incompatible charset raises UnicodeDecodeError; errors='ignore' can bypass this.
Expected output
Decode failed
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.
