What this snippet does
map distributes an iterable across worker threads, preserving order of results.

Why practise typing this
Typing concurrency (locks & executors) 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.
