Capital letter counter

Write a function @cap_let_counter(s)@ that returns the number of capital letters in string $s$. You can use the string method @isupper()@ to check whether given an string it has at least one letter and all its letters are capital letters. For instance, @my_string.isupper()@ is True when @my_string@ is ’HELLO’ or ’1X2’ or ’G’ and is False when @my_string@ is ’He7TO’ or ’x’ or ’123456’.
