Number of elements in Python Set
- by Tim
I have a list of phone numbers that have been dialed (nums_dialed).
I also have a set of phone numbers which are the number in a client's office (client_nums)
How do I efficiently figure out how many times I've called a particular client (total)
For example:
>>>nums_dialed=[1,2,2,3,3]
>>>client_nums=set([2,3])
>>>???
total=4
Problem is that I have a large-ish dataset: len(client_nums) ~ 10^5; and len(nums_dialed) ~10^3.
