1) Is the byte-compiled .pyc file and optimized .pyo file platform-independent?(including python versions 3.x)

Yes.

If yes, is it guaranteed to stay that way in future?

Yes.

2) If the the generation of .pyc file fails (say, due to write protected area), does that stop the script execution?

No. It only means the bytecode won't be cached.

3) Is it possible to redirect the location of the generation of .pyc files to other than that of the corresponding .py files?

I think some support for this has been developed, at least experimentally, but I'm not sure if it's part of a stable release or not. It's more likely in Python 3.x, which I'm significantly less familiar with. -Fred -- Fred L. Drake, Jr. <fdrake at gmail.com> "Chaos is the score upon which reality is written." --Henry Miller
