python 3中字典值的总和

Question

I have the following dictionary:

dic= {'I-setosa': 8, 'I-versicolor': 2, 'I-virginica': 0}

How can i find the sum of the keys? In Python 2 I could do the following:

sum(dic.values())

Is there any other way than this? I tried using dic.values() and find the sum of that list, but it is too lengthy.

Answer 1

 sum(dic.values()) 

Is there any other way than this?

Sure. Infinitely many. But why are you asking? That's the right way to do it.
