Since Python is a symbolic language, it is relatively easy to reconstruct the
original python source code from the *.pyc files. See

Re: Perl 6: Protecting Intellectual Property for Commercial Code

[Parrot Raiser]

Frankly, if you're worried about this sort of thing, you have too much
faith in "secret sauces", and not enough in understanding situations
thoroughly. Code is trivial, implementation isn't.

Back in the days of dBase II, I was a contractor for one ministry of
the local government. They asked me to write a little system to do a
particular job   (As much an experiment to see if these new "desktop
computers" were useful tools or just cute toys as for the actual
outcome.) It was clearly applicable to other branches, so I made it
appropriately generalisable from the start.

Some of the other ministries contracted me to adapt the
government-owned code for them.  I had a lot less cleaning up to do
where they said "Please install it for us" than when managers had
hijacked the code and tried to implement it as their own creation.

Sometimes, but not always. Remember that the default for answered questions
is reverse by rating, so the topmost answer will be the higest rated one;
you can change the sort order, and occasionally can observe it in an
intermediate state before it re-sorts the (cached?) page. As such it's no
worse than any other crowdsourced site/resource (including pre-Internet
ones like Consumer Reports or the U.S.'s Better Business Bureau).

Re: who own my code?

[Parrot Raiser]

I agree that this is really not the appropriate forum for this. Type a
question like "if I write the same code for several clients, who owns
it?" into a search engine, and you'll get a plethora of links.

In this case, I would say the fairest thing is to write the sharable
portion once on your own time, then charge all the clients the same
for the core and time-and-materials for the tailoring.
