Solve the following python programming problem given the following code:
def TDictOf(key_type, val_type) : 
    'Checks a dict type for the type of its key/values.

  ' 
    desc = WithDesc (('Dictionary with keys of %s and values of %s' % (Parens (key_type), Parens (val_type)))) 
    def fn(container) : 
        return (compat.all ((key_type (v) for v in container.keys ())) and compat.all ((val_type (v) for v in container.values ()))) 
return desc (TAnd (TDict, key_type)) 

    
    

    Fix the buggy line: return desc (TAnd (TDict, key_type))
