Solve the following python programming problem given the following code:
def _get_filters() : 
    from nova.scheduler import filters 
    def get_itm(nm) : 
        return getattr (filters, nm) 
return [get_itm (itm) for itm in dir (filters) if ((type (get_itm (get_itm)) is types.TypeType) and issubclass (get_itm (itm), filters.AbstractHostFilter) and (get_itm (itm) is not filters.AbstractHostFilter))] 

    
    

    Fix the buggy line: return [get_itm (itm) for itm in dir (filters) if ((type (get_itm (get_itm)) is types.TypeType) and issubclass (get_itm (itm), filters.AbstractHostFilter) and (get_itm (itm) is not filters.AbstractHostFilter))]

#Here is Python code to fix the buggy line: return [get_itm (itm) for itm in dir (filters) if ((type (get_itm (get_itm)) is types.

return [get_itm (itm) for itm in dir (filters) if ((type (get_itm (itm)) is types.TypeType) and issubclass (get_itm (itm), filters.AbstractHostFilter) and (get_itm (itm) is not filters.AbstractHostFilter))]
