How can I verify if the content of a variable is a list or a string?

[Andres Soto]

Hi,
I'm writing a function which receive a list which elements are strings or new lists (sublists) containing strings. 

How can I verify if sone element of the list (which is contained in a variable) is a list or a string?
I found the method isinstance(object,class) but I don't know which class should I use for.
Thank you, regards
