Python does not have Switch/Case statements, and likely never will.

How to get pythonic switch functionality?
{
key_1: function_1,
key_2: function_2,
key_3: function_3,
key_4: function_4
}.get(x, defaultFunction)()
Advantages of this structure are:
- Any first-class type may be a key: including other functions.
- Access is in constant time (O(1)).
- There is a defaultFunction() to handle invalid keys.
- Late binding of the functions allows for dynamic code.
- The dictionary may be stored after it is created to improve speed (see article): the dictionary is interpreted a single time.
- A dictionary may be selected and then a function generated from that dictionary (see article).
