Sentinel“工作”是因为它结束了程序，但并非没有输出以前库存的数据（这是错误的）。我希望哨兵立即停止该程序并踢到“＆gt;＆gt;＆gt;”输入'-999'后。这是输出的样子：

============= RESTART: C:\Users\ElsaTime\Desktop\answer2.py =============
Enter stock name OR -999 to Quit: M$FT
Enter number of shares: 1000
Enter purchase price: 15
Enter selling price: 150
Enter commission: 0.03

Amount paid for the stock:       $  15,000.00

Commission paid on the sale:     $   4,500.00
