What this snippet does
Python ignores type hints at runtime, allowing incompatible types to be passed unless checked manually.
Expected output
23
Why practise typing this
Typing variables & types 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.
