如何在輸入文件給定的列表中按順序獲取和打印列表

Question

對於特定場景，我使用列表 append 的組合並擴展以獲得所需的 output，但它沒有給出預期的 output。下面的代碼給出了 output [['test1', 'test2'], 'test3', 'test4', 'test5', 'test6', ['test5', 'test6']]正如我所期望[['test1', 'test2'], ['test3', 'test4', 'test5', 'test6'], ['test5', 'test6']] 。 如果我想更改密鑰（輪胎 1、輪胎 2、輪胎 3）順序，它應該以新順序打印 output。

任何提示/建議都會很有幫助。 謝謝

輸入.json

{
    "tire1": {
        "source": [ "{{ 'PEP' | YYYYYYY | join }}" ]
    },
    "tire2": {
        "source": [ "{{ 'REP, DEP' | LLLLLL | join }}" ]
    },
    "tire3": {
        "source": [ "{{ 'DEP' | LLLLLL | join }}" ]
    }
}

數據.json

{ 
    "PEP": {
        "tire2": {
            "tire3": {
                "compname": "test1"
            },
            "tire4": {
                "compname": "test2"
            }
        }
    },
    "REP": {
        "tire2": {
            "tire3": {
                "compname": "test3"
            },
            "tire4": {
                "compname": "test4"
            }
        }
    },
    "DEP": {
        "tire2": {
            "tire3": {
                "compname": "test5"
            },
            "tire4": {
                "compname": "test6"
            }
        }
    }
}

測試.py

    if isinstance(inputDict, dict):
        if key in inputDict:
            yield inputDict[key]

        for i in data:
            if i == parentInputKey:
                Dict[i] = data[i]
        return list(findkeysvalues(Dict, key))

    with open("input.json") as jsonFile:
        data = json.load(jsonFile)
    lst = []
    rules_items_source = list(findkeysvalues(data, "source"))
    for i in rules_items_source:
        listtostring = ' '.join([str(el) for el in i])
        y = listtostring.split("|")
        x = re.findall("\w+", y[0])
        if len(x) != 1:
            for j in x:
                source = process_JSON_value("data.json", j, "compname")
                lst.extend(source)
        else:
            source = process_JSON_value("data.json", x[0], "compname")
            lst.append(source) 
    print(lst)

elements()

將您的 if 塊更改為此代碼：

if len(x) != 1:
            source = []
            for j in x:
                source.extend(process_JSON_value("data.json", j, "compname"))
            lst.append(source)

Output 與您當前的 input.json

[['test1', 'test2'], ['test3', 'test4', 'test5', 'test6'], ['test5', 'test6']]

如果我像這樣向 input.json 添加額外的值：

"tire2": {
        "source": [ "{{ 'PEP, REP, DEP' | LLLLLL | join }}" ]
    }

然后是 output：

[['test1', 'test2'], ['test1', 'test2', 'test3', 'test4', 'test5', 'test6'], ['test5', 'test6']]
