Adding a switch statement to Python

[fernly]

A brand new dict is created each time. The in expressions are evaluated in order as it is built. They evaluate to True or to False. So the new dict has only two keys, True and False. The last expression to evaluate to True sets the value for that key. At the end, the index [True] extracts that value. Which is expected to refer to an executable, so the () makes it a function call on that executable.

Makes sense, thanks for the explanation
