How to sum all the values in a dictionary?

Question

Let\'s say I have a dictionary in which the keys map to integers like:

d = {\'key1\': 1,\'key2\': 14,\'key3\': 47}

Is there a syntactically

Answer 1

I feel sum(d.values()) is the most efficient way to get the sum.

You can also try the reduce function to calculate the sum along with a lambda expression:

reduce(lambda x,y:x+y,d.values())
