What this snippet does
The type statement supports recursive definitions and generics cleanly without TypeAlias.
Expected output
{'a': 1}Why practise typing this
Typing typing (modern python 3.12+) 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.
