It shouldn't at the moment - unless you have PYTHONOPTIMIZE set. A 
future version will allow you to disable them.

A deployed application doesn't do anything different to a "traditional" 
application - PyQt is identical.

Regarding debugging then print() should work. I don't know how eric 
implements remote debugging (by including some stub code?), but I don't 
see why that can't continue to work.
