Question

Is ternary iteration possible? A simplistic version of what I mean, though this particular example could be done in a better way:

c = 0  
list1 = [4, 6, 7, 3, 4, 5, 3, 4]  
c += 1 if 4 == i for i in list1 else 0  

A more practical example:

strList = ['Ulis', 'Tolus', 'Utah', 'Ralf', 'Chair']
counter = 0  
counter += 1 if True == i.startswith('U') for i in strList else 0  
return counter  

Answer 1

Your “practical example” is written as:

>>> strList = ['Ulis', 'Tolus', 'Utah', 'Ralf', 'Chair']
>>> sum(1 for el in strList if el.startswith('U'))
2

Your other example (if I understand correctly) is:

>>> list1 = [4, 6, 7, 3, 4, 5, 3, 4]
>>> list1.count(4)
3

(or just adapt the strList example, but nothing wrong with using builtin methods)
