Solve the following python programming problem given the following code:
def markdown2rst(text) : 
    'Convert a Markdown string to reST via pandoc.

    This is very similar to nbconvert.filters.markdown.markdown2rst(),
    except that it uses a pandoc filter to convert raw LaTeX blocks to
    "math" directives (instead of "raw:: latex" directives).

    ' 
    def rawlatex2math_hook(obj) : 
        if ((obj.get ('t') == 'RawBlock') and (obj ['c'] [0] == 'latex')) : 
            obj ['t'] = 'Para' 
            obj ['c'] = [{ 
                't' : 'Math', 
                'c' : [{ 
                    't' : 'DisplayMath', 
                    'c' : [], 
}, obj ['c'] [1]], 
}] 
return obj 
def rawlatex2math(text) : 
        json_data = json.loads (text, object_hook = rawlatex2math_hook) 
        return json.dumps (json_data) 
rststring = pandoc (text, 'markdown', 'rst', filter_func = rststring) 
    return re.sub ('^(\\s*)\\.\\. math::$', '\\1.. math::\\1   :nowrap:', rststring, flags = re.MULTILINE) 

    
    

    Fix the buggy line: rststring = pandoc (text, 'markdown', 'rst', filter_func = rststring)

#Here is Python program to fix the buggy line: rststring = pandoc (text, 'markdown', 'rst', filter_func = rststring)
.

rststring = pandoc (text, 'markdown', 'rst', filter_func = def rawlatex2math()
