＆＃13;

我遍历所有子类别，如下所示：

row = 1

def TraverseJSONTree(jsonObject, count=0):
    title = jsonObject.get('title')
    url = jsonObject.get('url')

    print 'Title: ' + title + ' , Position: ' + str(count)

    worksheet.write_string(row, count, title)
    worksheet.write_string(row, 6, url)
    global row
    row+=1 

    subCategories =  jsonObject.get('subCategory',[])

    for category in subCategories:
        TraverseJSONTree(category, count+1)


for jsonObject in json.loads(jsonArray):
    TraverseJSONTree(jsonObject)

预期结果

Answer 1

row = 1

def TraverseJSONTree(jsonObject, main_title=None, count=0):
    if main_title is None:
        main_title = title = jsonObject.get('title')
    else:
        title = jsonObject.get('title')
    url = jsonObject.get('url')

    print 'Title: ' + title + ' , Position: ' + str(count)

    if main_title is not None:
        worksheet.write_string(row, 0, title)
    worksheet.write_string(row, count, title)
    worksheet.write_string(row, 6, url)
    global row
    row+=1 

    subCategories =  jsonObject.get('subCategory',[])

    for category in subCategories:
        TraverseJSONTree(category, main_title, count+1)

for jsonObject in json.loads(jsonArray):
    TraverseJSONTree(jsonObject)

它将返回您的预期输出，因为它需要检查类别是否存在然后您必须将excel reamin的第0列上的原始标题改为相同。

Answer 2

修改： 最简单的方法是使用csv模块，比如我们在变量a中有整个json

public function __construct($some, $constructor, $arguments) {
  // .. etc
}

您将在同一位置拥有所需的csv。这只适用于两个子类别（因为我已经检查了你给出的数据并说只有两个类别（即1和1.1））但是如果你想重复多次（我知道它不是最有效的方式）在如此短的时间内无法想到任何事情）

您还可以使用pandas模块转换字典     将pandas导入为pd     pd.DataFrame.from_dict（dcitionaty_element）

然后在json中的所有字典上进行并合并它们并将其保存到csv文件中。

您可以使用可用的python代码here
