访问与条件匹配的嵌套字典值

Question

我想做的是遍历这本字典，只抓取其中包含 "RM" 的键（包括它们的值）。

我试过类似的东西：

for key, val in release_dict["packages"].items():
        for k, v in val.items():
            print(item for item in v["linked_jiras"] if "RM" in item)

一点运气都没有。

我被困在这里

{
    "packages": {
        "company-web-package-name": {
            "linked_jiras": {
                "RM-2048": "info we want",
                "RM-2087": "info we want",
                "item": "description",
                "item": "description",
                "item": "description",
                "item": "description",
                "item": "description",
                "item": "description",
                "item": "description",
                "item": "description",
                "item": "description",
            },
            "branch": "master",
            "project_lead": "person"
        },
        "company-web-package": {
            "linked_jiras": {
                "RM-1880": "info we want",
                "item": "description",
                "item": "description",
                "item": "description",
                "item": "description",
                "item": "description",
                "item": "description",
                "item": "description",
                "item": "description",
                "item": "description",
            },
            "branch": "master",
            "project_lead": "person"
        },
        "company-web-package--internal": {
            "linked_jiras": {
                "RM-2049": "info we want",
                "item": "description",
                "item": "description",
                "item": "description",
                "item": "description",
                "item": "description",
                "item": "description",
                "item": "description",
                "item": "description",
                "item": "description",
            },
            "branch": "master",
            "project_lead": "person"
        }
    }
}

我正在尝试获取这些结果的新字典，或者更简单地说是获取这些值的元组。

您需要稍微重新排序循环并添加到输出字典以获取所有信息：

d = {}

for key, val in release_dict["packages"].items():
    for item in val["linked_jiras"]:
        if "RM" in item:
            d[item] = val["linked_jiras"][item]

print(d)
# {'RM-2048': 'info we want', 'RM-2087': 'info we want', 'RM-1880': 'info we want', 'RM-2049': 'info we want'}

注意：确保如果您使用的是字典，所有 'RM' 键都是不同的。
