如何打印字典中重复键的值？

Question

它仅打印嵌套标题中的最后一个键值对。

这是我正在使用的代码：

def displayAllTabs(dict_items):

for dict in dict_items:
    
    title = dict.get("Title")
    print(title)

    if "NestedTabs" in dict.keys():

        nestedTitle = dict["NestedTabs"]["Title"]
        print(f'\t{nestedTitle}') 

这是我的清单：

[
    {
        "index": 1,
        "Title": "SE Factory",
        "Url": "https://www.sefactory.io",
        "NestedTabs": {"Title": "UI", "Url": "https://www.sefactory.io/uix"},
    },
    {"index": 2, "Title": "Google", "Url": "https://www.google.com"},
    {
        "index": 3,
        "Title": "W3schools",
        "Url": "https://www.w3schools.com",
        "NestedTabs": {
            "Title": "Html",
            "Url": "https://www.w3schools.com/html/default.asp",
            "Title": "Css",
            "Url": "https://www.w3schools.com/css/default.asp",
            "Title": "JavaScript",
            "Url": "https://www.w3schools.com/js/default.asp",
        },
    },
]

例如：在 w3schools 嵌套选项卡中，它仅打印 Javascript 标题。

尝试使用此解决方案

def displayAllTabs(dict_items):
    for item in dict_items:
        title = item.get("Title")
        print(title)

        if "NestedTabs" in item:
            nested_tabs = item['NestedTabs']
            if "Title" in nested_tabs and "Url" in nested_tabs:
                nested_title = nested_tabs["Title"]
                nested_url = nested_tabs["Url"]
                print(f'\tNested Tab: {nested_title} ({nested_url})')
            elif isinstance(nested_tabs, list):
                for nested_tab in nested_tabs:
                    nested_title = nested_tab.get("Title")
                    nested_url = nested_tab.get("Url")
                    print(f'\tNested Tab: {nested_title} ({nested_url})')

dict_items = [
    {
        "index": 1,
        "Title": "SE Factory",
        "Url": "https://www.sefactory.io",
        "NestedTabs": [{"Title": "UI", "Url": "https://www.sefactory.io/uix"}],
    },
    {"index": 2, "Title": "Google", "Url": "https://www.google.com"},
    {
        "index": 3,
        "Title": "W3schools",
        "Url": "https://www.w3schools.com",
        "NestedTabs": [
            {"Title": "Html", "Url": "https://www.w3schools.com/html/default.asp"},
            {"Title": "Css", "Url": "https://www.w3schools.com/css/default.asp"},
            {"Title": "JavaScript", "Url": "https://www.w3schools.com/js/default.asp"},
        ],
    },
]

displayAllTabs(dict_items=dict_items)

您需要将“NestedTabs”字典的项目放入列表中。我想不出任何其他方法可以在不遇到错误的情况下检索该信息。
