hiding modules in __init__.py

How would I implement something equivalent to java's package private in
python?

Say if I have

package/__init__.py
package/utility_module.py

and utility_module.py is an implementation detail subject to change.

Is there some way to use __init__.py to hide modules that I don't want
clients to see? Or is the best practice just to name the module you don't
want clients to use _utility_module and have it private by convention?

Thanks,
Brendan

Generally the latter on account of Python's "we are all consenting
adults here" philosophy.

If you don't import utility_module in __init__ (or delete the name after
using it), it won't show up if someone does "from package import *", nor
in dir(package). Plus if you don't menction it in the docs, the only way
to discover it would be to look at the directory contents - to "peek the
implementation", I'd say.
You could always name it _utility_module.py if you want to make perfectly
clear that it's for internal use only, but I've seldom seen such module
names.
