Hello Everyone,

If I've done this incorrectly, please let me know so that I can improve/revise. I'm new to the Python community and quite enjoy the more functional features of Python 3, but have I have a peeve about it. I'd like to propose and discuss the following enhancement to Python 3:

Consider the following trivial for-loop:
chars = "abcaaabkjzhbjacvb"
seek = {'a','b','c'}
count = 0
for a in chars:
     if a in seek:
          count += 1
  
Gross. Twice nested for a simple count.

count = 0

for a in chars:

count = count + 1 if a in seek else count

Once nested -- if nested == gross, then this is not gross. (However, I prefer the twice nested which I find clear and simple -- not gross.)
