Can anyone show me how I can calculate the number of unique values within the list of each record using Python?

For example, what is the count of "Primary" or "Repair"?

I know that I can do this easily by exploding the list and go from there. But since I have over 1mil lists, I think the best way to do it is to take advantage of Python to improve performance. Thanks in advance!

Have you looked at the ListHistogrammer? Would that get you what you need?

I will take a look at that transformer.

But this solved my problem:

 

import fme

from collections import Counter

import fmeobjects

my_list = feature.getAttribute('Business_Points_List{}.ODP Category')

for x in range(0,20):

print Counter(my_list).keys())x]

print Counter(my_list).values())x]

feature.setAttribute(Counter(my_list).keys())x], Counter(my_list).values())x])
