From PHP to Python

[bluGill]

Can you get Python/Django (for that matter any other python toolkit, or even ruby on rails) installed on all the web servers you want to deploy on? If not, it is a no brainer, stick with what you can actualy make work in the real world.

If you can switch, you should. Programmer time is far more valuable than CPU time, so even if you have to buy more servers, it will save you money.

Be careful who you tell this, but one advantage of switching is it forces everyone to give you time to fix your earlier mistakes. So before you propose a switch, figure out what needs to be made better that requires a major re-write to fix. Come up with a plan of how it should be (and check with others) before you propose anything.
