By the look of this code, it's expecting a string. (The variable name
"instring" is suggestive of this, and strings DO have an expandtabs
method.) You're calling a method named "parseString", and presumably
giving it a list. I don't know what you mean by "nested" though.
Maybe you want to iterate over the list and parse each of the strings in it?
More info about what you're trying to do here would help.
