Answer 1

This would be my version:

s=input()
print(*(f'{l}: {s.count(l)}' for l in set(s)), sep='\n')

Answer 2

I did use the for loop. Even if you don't use it by syntax, any function or method that you use will have a for loop running in the background.

Answer 3

import collections
for x in collections.Counter(input("Type in a string:-").replace(" ", "")).most_common():
print(x[0], ':', x[1])
