To support different version of code, you might end up using try catch code bloc. But, in the worst cast, what is the cost overhead of throwing an exception every-time?
You might have the possibility to use in some case the hasattr to avoid throwing an exception but your code will be less elegant and/or readable.
In order to make a rational decision, let's compare the time cost. I was expecting a major cost for throwing exception but it ends up been only 2 times more costly then doing an hasattr.
You can see the simple code I have used to compare it here. From now on, I will be less scare about memory performance when I am using try catch.
