Why did you repeatly omit the \n after 0? Please paste code that ran
Gross. Twice nested for a simple count.
Twice indented does not particularly bother me.

*We could do this:*
chars = "abcaaabkjzhbjacvb"
seek = {'a','b','c'}
count = sum([1 for a in chars if a in seek])
However, this changes important semantics by creating an entire new
list before summing.
Unnecessary. Use a generator comprehension (expression).
sum(1 for a in chars if a in seek)
chars = "abcaaabkjzhbjacvb"
seek = {'a','b','c'}
count = 0 # fixed
for a in chars if a in seek: count += 1
Rejected and rejected again, any mixing of keyword clauses like this
except in comprehensions. The sum expression is shorter and only 1 line.
