Write a function @cap_let_counter(s)@ that returns the number of
capital letters in string
.
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’.
