python - Python3: How to provide module exports as convenience at the package level? -


hopefully question won't me python hall of shame.

anyway, have package poo contains single module moo. in future, there might additional modules inside poo (such poo.moose). let's assume moo kind of main-use module , users want have things in moo ready @ hand when import poo, package. (and package users) avoid import poo.moo, import poo.moo moo, , (gasp!) import poo.*. know, saving typing thing.

so idea (which not off right way) copy "exports" (functions, variables, classes, ...) of module poo.moo package poo, in __init.py__. don't want overwrite existing definitions in poo though.

what correct, good, proper, , efficient way achieve this? (did use "ideal"? nah!) or bad idea @ all? or highly spirited python in sense of "...and different"? ;)

oh, packages python3 only.

please note in python, how import classes module without keeping imported module's namespace? has answer, did not understand how apply __init__.py code of python package. reason, detailed answer below gives such additional details.

turns out easy. in package poo/__init__.py (absolute) import of module package namespace:

from poo.moo import *

that's it. when there's poo.moo.a() become accessible poo.a() too.

please note package definitions aren't overwritten (sub) module import, intention: poo.moo.version=42 doesn't overwrite poo.version=13. needed.

i notice i'm still addled other modularized languages imports stay private module. in python in plain view, package imports in module/package.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
