def test (n): if (n==1): return False elif (n==2) : return True; else: for x in range (2,n) : if ( n \% x==0): return False return True class My_Class: def sub_sets (self, sset): return self.recur([], sorted(sset)) def recur (self, current, sset): if sset: return self.recur(current, sset [1:])+ self.recur(current+[sset [0]], sset [1:]) return [current] sample_instance = My_class() print(sample_instance.sub_sets ([7,4]))
