intersection of three sets in python?
- by Phil Brown
Currently I am stuck trying to find the intersection of three sets. Now these sets are really lists that I am converting into sets, and then trying to find the intersection of.
Here's what I have so far:
for list1 in masterlist:
list1=thingList1
for list2 in masterlist:
list2=thingList2
for list3 in masterlist:
list3=thingList3
d3=[set(thingList1), set(thingList2), set(thingList3)] setmatches c=
set.intersection(*map(set,d3)) print setmatches
and I'm getting
set([])
Script terminated.
I know there's a much simpler and better way to do this, but I can't find one...
