Solve the following python programming problem given the following code:
def parse(codelet) : 
    "
    Dispatches the codelet to the correct parser based on its language.
        It is the job of the respective parsers to accumulate data about the
        code and to convert it into a string representing a python dict.
        The codelet is then given dict as its 'symbols' field.

    :param codelet: The codelet object to parsed.

    :type code: Codelet
    " 
    lang = _lang (codelet) 
    lang_string = LANGS [lang] 
    codelet.language = lang 
    def loc_helper(l) : 
        for i in l : 
            if (i == (- 1)) : 
                (yield None) 
else : 
                (yield i) 
if (lang_string in PARSERS) : 
        symbols = PARSERS [lang_string] (codelet) 
        symbols = { key : [(name, [tuple (loc_helper (loc)) for loc in syms [name] ['assignments']], [tuple (loc_helper (codelet)) for loc in syms [name] ['uses']]) for name in syms] for (key, syms) in symbols.iteritems () } 
        codelet.symbols = symbols 

    
    

    Fix the buggy line: symbols = { key : [(name, [tuple (loc_helper (loc)) for loc in syms [name] ['assignments']], [tuple (loc_helper (codelet)) for loc in syms [name] ['uses']]) for name in syms] for (key, syms) in symbols.iteritems () }
