我得到了一个使命，写一个代码到杂货店购物清单，每一个数字，我把应该激活其他功能。我得到了3个问题，在这个代码。
1.更大的问题是当我输入数字9时循环应该中断，但这不是中断。
1.在函数how_moch_product_name_in_list中，我需要一个for循环，它将how_much_products加1，就像相同名称的产品的数量一样，它总是写1，因为如果我输入beer，循环将运行1次。例如，如何正确地更改和写它。
1.我试着把可迭代的number写为int，就像number = int(input())一样，而if语句的其余部分也写为int，他给我写了'int' object is not iterable，我需要如何把它修改为int，这样就可以了？这是完整的代码。
