However, this changes important semantics by creating an entire new
list before summing.
Creating the list is pointless in this case - sum will take any
iterable, including a generator expression:
chars = "abcaaabkjzhbjacvb"
seek = {'a','b','c'}
count = sum(1 for a in chars if a in seek)
So you haven't really changed any semantics - and it seems that this is
far better than fiddling with the for loop syntax.
