把results_list中两个字典元素的值相加求和。
如:
sales_amount = sum((int(item['salesAmount']) if 'salesAmount' in item else 0) for item in results_list) sales_sum = sum((int(item['salesNum']) if 'salesNum' in item else 0) for item in results_list)
表达式解释：先循环获取到列表中的字典元素，再根据字典的key获取值，获取到字典元素后，判断key是否在字典中，如果在就转化成int类型，否则直接赋值0；
