What this snippet does
Closures capture variables by reference, not value; late binding means they all see the final loop value.
Expected output
[2, 2, 2]
Why practise typing this
Typing functions 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.
