Not at all. Think of the C switch block... if you read about it in the K & R you'll think its useless... because it can only switch on a SINGLE character. So, to make it work what do you do??? You create some constants that are actually really and totally just a number... one character... that represents GT_1 or anything else.
The switch block "switches" on a character in C. In python it could switch on absolutely anything we like... the point is not how it switches... but how it "looks" to human beings, and "maybe" how it performs.
For me its more important that code be readable first and foremost... then optimized. Yes, I can use if elif else blocks and I can and do use dict dispatch tables.... but I "wish" there were a switch case default block in python so that some things could be coded to be clearer to a human reader.
just sayin... not arguing though... just a comment.
