Taming Dwarf Burms (P.b.progschai)

Here is a question - how is the best way to tame or calm down a Dwarf Burmese Python (Python bivittatus progschai).

I have had mine for about 10 months, now. I estimate they are about 1 year old - at present time. At present they are about 2 feet in length. They are definitely 100% pure progschai - roughly F1-F2 generation of Bob Clark stock.

I feed them regularly about every 7-14 days - with rodents which are roughly equal to their girth. So far I can move them using a snake hook with very little difficulty. As far as handling goes - they are still very defensive. So I regularly use leather gloves - when attempting to handle them.

What I am wondering - is about how much long will it take for them to tame down?
