Sorting Lists of Dictionaries
Frequently you want to sort a list of dictionaries, based on some particular key.
There are many ways to do this. Here's the fastest way to do it, as it avoids using a custom comparison function, instead using builtin comparisons. This is the decorate-sort-undecorate pattern, or the Schwartzian transform if you're coming from Perl.
In case you're wondering, the variable is named dict_ because we want to have MeaningfulNames, but we don't want to shadow the dict builtin, so we append an underscore.
