reflection - Python `setattr` for functions? -


this question has answer here:

let's have class a so:

class a:     def __init__(self):         self.a =     def __add__(self, other):         return other + 1

then, run following code in console:

>>> = a() >>> a.a <<< 1 >>> setattr(a, 'a', 2) >>> a.a <<< 2 >>> + 2 <<< 3 >>> setattr(a, '__add__', lambda s, o: o - 1) >>> + 2 <<< 3

is there way change class functions this?

note works non-__ functions, though interestingly enough, if set function f, function shouldn't take self parameter.

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
