Lowercase letter counter

Write a function @low_let_counter(s)@ that returns the number of
lowercase letters in string s. You can use the string method @islower()@
to check whether given an string it has at least one letter and all its
letters are lowercase letters. For instance, @my_string.islower()@ is
True when @my_string@ is ’good morning’ or ’2 x 5’ or ’z’ and is False
when @my_string@ is ’Good morning’ or ’Z’ or ’123456’.
