=== Python Recipies
Vijay took an excellent session on Python Recipes
for writing switch case and enum in python.
He first explained switch case with a global variable
. But Switch implemented using Global variable
will corrupt the global variable if we are using
nested switch.So he replaced it with by creating instances.
Then he explained *args for checking multiple cases in
each switch case.
Then he took how to create enum
1. enum(STATE, ["KING","QUEEN","PAWN"])
2. He explained about type function to create instances
>>> test=type("STATE",(object,),{'king':0,'QUEEN':1,'PAWN':2})
>>> test
<class '__main__.STATE'>
>>> test.QUEEN
1
>>>
Then he took about __slot__ in order to
to avoid modifying Values in runtime.
While explaining enum he also explians
some basics of creating objects.
