Yes, of course you do.

Really, it's not at all that difficult.  Anyway, the namespaces are
there to protect you and simplify the code.  Although you could think
of it as a small inconvenience to have to put imports for various
things wherever you need them, the alternative is vastly more of a
problem.

I never use IDLE, so I can't say.  My preferred approach is simply
running things from the command line (but you get that way when you
start focusing on unit testing rather than code-and-fix...).
