6位毫秒的python datetime

Question

我如何以下面的格式打印 6 位毫秒数

>>> import datetime
>>> datetime.datetime.now(tz = datetime.datetime.now().astimezone().tzinfo).isoformat(timespec='milliseconds')
'2022-01-10T18:29:10.698000+05:30'

实际输出:

 '2022-01-10T18:29:10.108+05:30'

期望输出是这样的:

  '2022-01-10T18:29:10.108000+05:30'

Answer 1

使用timespec=microseconds:

>>> dt = datetime.datetime.now(tz = datetime.datetime.now().astimezone().tzinfo).isoformat(timespec='microseconds')
'2022-01-10T14:05:55.742931+01:00'

更新:

如果你想要 0 作为微秒值，你可以这样做:

now = datetime.datetime.now().astimezone()
now = now.replace(microsecond=now.microsecond // 1000 * 1000)
now = now.isoformat(timespec='microseconds')
print(now)

# Output
'2022-01-10T14:17:08.386000+01:00'
