Is there a method that returns a character at a specified index?

You mean like:

 >>> "python"[0]
"p"
 >>> "python"[1]
"y"

?  Though from what you say, regular expressions are what you are 
looking for.  For example, to check if a string contains only letters: 
re.search(r'^[a-z]+$', word).  Or re.search("^[%s]+$" % re.escape(SSS), 
word).
