如果其中一个值大于零，如何比较两个字典并打印
[英]How to compare two dictionaries and print if one of the values are above zero
问题描述
我一直在尝试使用 JSON object ，我一直在尝试从两个不同的键中获取值。 我想要做的是检查 object 1 中是否包含 object 2 并且值超过 0 然后我想打印出来。
get_json = json.dumps({

所以我所做的是我在一个列表中创建了两个字典：
first_loop = []
second_loop = []
total_stock = 0
for idx, sizes in json_value["attributes"].items():
for getId in sizes["options"]:
first_loop.append({getId["label"]: getId["products"][0]})
break
for idx, test in json_value["productStockAlert"]["child"].items():
total_stock += test["stock_number"]
second_loop.append({test["productId"]: test["stock_number"]})
print("first_loop", first_loop)
print("second_loop", second_loop)
print("total_stock", total_stock)
返回：
first_loop [{'38': '69813'}, {'38,5': '69817'}, {'39': '69818'}, {'40': '69819'}, {'40,5': '69820'}, {'41': '69821'}, {'42': '69822'}, {'42,5': '69823'}, {'43': '69824'}, {'44': '69814'}, {'44,5': '69815'}, {'45,5': '69816'}]
second_loop [{'69813': 0}, {'69814': 5}, {'69815': 3}, {'69816': 1}, {'69817': 0}, {'69818': 0}, {'69819': 0}, {'69820': 0}, {'69821': 3}, {'69822': 4}, {'69823': 6}, {'69824': 6}]
total_stock 28
我的问题是如何从first_loop比较我检查 ID（等 69816）在 second_loop 中并且值高于 0，如果高于 0，那么我想将它添加到 append 到新列表等： 45,5 (1) （这是来自 first_loop 的大小数字和来自 second_loop 的数字（值）。
Output 最终会：
>>> ["41 (3)", "42 (4)", "42,5 (6)", "43 (6)", "44 (5)", "44,5 (3)", "45,5 (1)"]

不确定这是否是最有效的方法，但您可以：
- 使字典不是列表，它需要是一个列表吗？
- 交换
first_loop的键值 - 与集合相交
- 从原始值获取值，仅在 > 0 时打印
[代码未测试]
first_loop = {}
second_loop = {}
total_stock = 0
for idx, sizes in json_value["attributes"].items():
for getId in sizes["options"]:
first_loop[getId["products"][0]] = getId["label"]
break
for idx, test in json_value["productStockAlert"]["child"].items():
total_stock += test["stock_number"]
second_loop[test["productId"]] = test["stock_number"]
matching = set(first_loop.keys()).intersection(second_loop.keys())
for prod_id in matching:
stock = second_loop.get(prod_id)
if stock > 0:
print(f"{first_loop.get(prod_id) ({stock})")
最后，你有一个break语句，这将使它只运行一次......在这种情况下你不需要一个for循环......
这太具体了，但希望它有帮助......

基本上，你只需要创建id-label mapping ， id-count mapping并将它们合并：
id_label_mapping = {o["products"][0]: o["label"] for o in next(iter(json_value["attributes"].values()))["options"]}
id_count_mapping = {o["productId"]: o["stock_number"] for o in json_value["productStockAlert"]["child"].values()}
result = [f"{l} ({id_count_mapping[k]})" for k, l in id_label_mapping.items() if id_count_mapping.get(k)]
在您的代码中，您犯了两个主要错误，这使得最后一步（合并）的实现更加困难。
- 您正在创建字典列表而不是具有不同键的单个字典；
- 在
first_loop，您使用label作为键，但在second_loop中，您使用的是productId 。
如果我们将修复这两个差距，您的代码将起作用：
first_loop = {}
second_loop = {}
total_stock = 0
for idx, sizes in json_value["attributes"].items():
for getId in sizes["options"]:
first_loop[getId["products"][0]] = getId["label"]
break
for idx, test in json_value["productStockAlert"]["child"].items():
total_stock += test["stock_number"]
second_loop[test["productId"]] = test["stock_number"]
result = []
for product_id, label in first_loop.items():
count = second_loop.get(product_id)
if count: # filters both None (key doesn't exit) and 0
result.append(f"{label} ({count})")
print("result", result)
print("total_stock", total_stock)
