python - how can I check the length of a list? -


i have list in python , want know number of "words"/"products" in it:

     print shopping_list

output: ['milk,cookies,apples']

now output should 3 1 , don't understand why :

    print len(shopping_list)

output: 1

note need 1 string contains words separated commas

your starting list is: 

shopping_list = ['milk,cookies,apples']

this list contains single string 'milk,cookies,apples' need adjust list below.

shopping_list = ['milk','cookies','apples']

your code function expected. list of strings can used calculate length.

you can python split list using comma indicator of new item.

shopping_list = ['milk,cookies,apples'] shopping_list = shopping_list[0].split(",") print shopping_list return  ['milk','cookies','apples']

note original shopping_list list need state want first item, index [0]

print len(shopping_list)

will return 3.

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.

android - Unable to generate FCM token from dynamically instantiated Firebase -

our business logic requires instantiate firebase during runtime. fetch firebase credentials (app id, api key etc.) default firebase location after knowing user's public key , create firebase instance using credentials. this means there 2 firebase instances used within app: the default "index" firebase gives credentials second the actual firebase intend use point forward the second firebase initialised this: firebaseapp app = firebaseapp.initializeapp(<context>, <options>, <app_label>); our problem traditional method of retrieving fcm token using firebaseinstanceidservice , ontokenrefresh() fails since ontokenrefresh() method called first firebase instance. directly calling string token = firebaseinstanceid.getinstance(app).gettoken(); returns null never ready when called. have tried polling test if token generated @ point. no luck. how can generate fcm token reliably firebase instance instantiated during runtime? i...
