【问题描述】：

我有一个包含这种格式的日期值的列表（datetime.datetime(2021, 9, 1, 8, 30, 25, 430000, tzinfo=tzlocal())）。我想将此日期值转换为 ISO 格式。目的是 CloudWatch Log Insight 无法读取此日期格式。

输出：

[{'timestamp': datetime.datetime(2021, 9, 1, 8, 30, 25, 430000, tzinfo=tzlocal()), 'type': 'ExecutionFailed', 'id': 22, 'previousEventId': 21, 'executionFailedEventDetails': {'error': 'States.TaskFailed', 'cause': '{"AllocatedCapacity":2,"Attempt":0,"CompletedOn":1630485024021,"ErrorMessage":"An error occurred while calling o80.getDynamicFrame.

向我们展示输入数据...
到目前为止你有什么尝试？
for i in lst: i['timestamp'] = i['timestamp'].isoformat()…?
这能回答你的问题吗？ Datetime to ISO 8601 in Python

【解决方案1】：

使用datetime.isoformat()

import datetime
from dateutil.tz import tzlocal

dt = datetime.datetime(2021, 9, 1, 8, 30, 25, 430000, tzinfo=tzlocal())
dt_iso = dt.isoformat()
print(type(dt_iso), dt_iso)

<class 'str'> 2021-09-01T08:30:25.430000+00:00
