Question

我正在尝试从此嵌套字典的时间戳中创建列表，但遇到了困难。

{
    '_class': 'org.jenkinsci.plugins.workflow.job.WorkflowJob',
    'builds': [
        {
            '_class': 'org.jenkinsci.plugins.workflow.job.WorkflowRun',
            'timestamp': 1571731200315
        },
        {
            '_class': 'org.jenkinsci.plugins.workflow.job.WorkflowRun',
            'timestamp': 1571731020310
        },
        {
            '_class': 'org.jenkinsci.plugins.workflow.job.WorkflowRun',
            'timestamp': 1571730995706
        }, {
            '_class': 'org.jenkinsci.plugins.workflow.job.WorkflowRun',
            'timestamp': 1571730900316
        }, {
            '_class': 'org.jenkinsci.plugins.workflow.job.WorkflowRun',
            'timestamp': 1571730600313
        }
    ]
}

我尝试了以下操作，但是由于第二个值本身包含一个嵌套的字典，因此它不像我想的那样解析时间戳：

dictList=[]
for key, value in dict.items():
    dictList.append([value])
print (dictList[1])

此尝试的输出如下：

[
    [
        {
            '_class': 'org.jenkinsci.plugins.workflow.job.WorkflowRun',
            'timestamp': 1571731200315
        },
        {
            '_class': 'org.jenkinsci.plugins.workflow.job.WorkflowRun',
            'timestamp': 1571731020310
        },
        {
            '_class': 'org.jenkinsci.plugins.workflow.job.WorkflowRun',
            'timestamp': 1571730995706
        },
        {
            '_class': 'org.jenkinsci.plugins.workflow.job.WorkflowRun',
            'timestamp': 1571730900316
        },
        {
            '_class': 'org.jenkinsci.plugins.workflow.job.WorkflowRun',
            'timestamp': 1571730600313
        }
    ]
]

我如何深入研究嵌套的内容并仅获取时间戳？

Answer 1

dict = {'_class': 'org.jenkinsci.plugins.workflow.job.WorkflowJob', 'builds': [{'_class': 'org.jenkinsci.plugins.workflow.job.WorkflowRun', 'timestamp': 1571731200315}, {'_class': 'org.jenkinsci.plugins.workflow.job.WorkflowRun', 'timestamp': 1571731020310}, {'_class': 'org.jenkinsci.plugins.workflow.job.WorkflowRun', 'timestamp': 1571730995706}, {'_class': 'org.jenkinsci.plugins.workflow.job.WorkflowRun', 'timestamp': 1571730900316}, {'_class': 'org.jenkinsci.plugins.workflow.job.WorkflowRun', 'timestamp': 1571730600313}]}

timestamps = []
for i in dict['builds']:
    timestamps.append(i['timestamp'])

print(timestamps)

我不清楚您要的是什么，但这可以将所有时间戳记入列表。
