Why do you want to do this? Exec and eval should -not- be used for
this
You can't sort dictionaries (as implemented by hash tables), they are
unordered data types, so by definition there's no way to force an order
on them.

There's already a grant in place for this. So hopefully someone

If what you're doing is wrong and backwards then it doesn't matter what
the question is. Best practices are best practices for a reason.
There's no reason to use eval to do what you want
Why are you using eval in the first place? This isn't bash. Use setattr
and getattr for dynamic attribute access.

What's wrong with:
def blah():
def _ (a, b, c):
a = a + 2
print "stmt 2"
return a+b/c
return doSomethingWith(_)
It's basically "anonymous", it just uses a name that you don't care
about. AFAIK, it can be immediately clobbered later if need be.
Otherwise, the function shouldn't be

Probably going to need more information about how mplayer is not being
accessed correctly.
CGI uses the shell environment to pass web information to a program...
so maybe this is messing up mplayer. You'll need to augment or wrap
your partners program in order to give you more information about

Why do you want to do this in a thread? What's wrong with
reactor.callLater?

It does what the OPs example does, but with numeric types.
