Solve the following python programming problem given the following code:
def parse_resources(resources) : 
    if isinstance (resources, dict) : 
        resources = [(re_fix (k), v) for (k, v) in resources.items ()] 
        def pattern_length(pair) : 
            (maybe_regex, _) = pair 
            return len (get_regexp_pattern (maybe_regex)) 
return sorted (resources, key = pattern_length, reverse = True) 
else : 
        if isinstance (resources, string_types) : 
            return [(re_fix (pattern_length), { 
                
})] 
else : 
            if isinstance (resources, collections.Iterable) : 
                return [(re_fix (r), { 
                    
}) for r in resources] 
else : 
                if isinstance (resources, RegexObject) : 
                    return [(re_fix (resources), { 
                        
})] 
else : 
                    raise ValueError ('Unexpected value for resources argument.') 

    
    

    Fix the buggy line: return [(re_fix (pattern_length), {
assistant
#Here is Python code to fix the buggy line: return [(re_fix (pattern_length), {
