How to find count length of dictionary values of list

Question

Hi. I have created a dictionary in python using lists. Now I want to find the length of the list. I tried doing this

len(d.values())

But it didn’t work. How can I get the count of values?

Answer 1

You should have used d.itervalues() instead and then used a loop to calculate the sum. Try this:

count = sum(len(v) for v in d.itervalues())
