Any legit way for using "if" statements and "for" loop while creating a dictionary in Python? - 


report['conditions'] += [    {     "name": cond,     "birad": br,     "findings":       [         {          "name": f,          **if f == 'mass':**             "parameters":             [             {              "name": iter_params_mass[0],              "value": create_rep(iter_params_mass, row, f, r)[0]             },{...}            ]         }     ]   }]

i have strict structure bson file, instead of creating manually, use if statement , for loop (if possible), because can have more 1 pair of name-value in parameters. efficient way it? thanks! i'm using python 3.6.0

sudo code how can done:

if f == 'mass':     # construct parameters loop maybe:     parameters = {key: value (key, value) in [('a','b'),('c','d')]}     # parameters = {'a': 'b', 'c': 'd'} else:     parameters = {key: value (key, value) in [('b','a'),('d','c')]}

then use parameters create final bson dict

report['conditions'] += [{"name": cond,                           "birad": br,                           "findings": [                               {"name": f,                                "parameters": parameters

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
