Of course: you can do *anything* in Python. I'm not sure this is to be
recommended, but since you ask ... if you have
then in some other module (and here specifically in the interactive
interpreter) you can bind a value to "myname" in __builtins__ and it
will be seen by mymod.py when it's imported:
>>> __builtins__.myname = "MyValue"
>>> import mymod
Having said all that, you have to be careful, since it's necessary to
explicity assign to __builtins__.myname to change the value - if you
just assign to myname then you create a new myname in the module's
global namespace that will make the name in __builtins__ inaccessible.
So, what with that plus the way the names automagically appear it's
probably something to relegate to the "definitely not best practice"
