What this snippet does

A decorator factory (@deco()) requires three levels of nesting, whereas a normal decorator (@deco) requires two.

Expected output

Must match nesting levels

Why practise typing this

Typing decorators (advanced) 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.
