python - multiple key (composite index) search in dict -


i have database table composite index this:

create table table1 ( key1 int, key2 int, value1 int, value2 char(10), primary key(key1 , key2) )

i have create dict table (using pyodbc, selection not issue). question is: how define multikey dict , after search data in it.

i achieve sql syntax in dictionary search:

select * table1 key1  = 10 , key2 = 20

a pseudo code search be:

myvalue = ['a', 'b'] if myvalue in mydict[key1, key2]:     print ('ok')

but wrong. idea?

a dict must have immutable type key. simplest such structure tupleof 2 database key fields. can use:

mydict[(key1, key2)]

and should work.

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
