    这是一个创建于 1887 天前的主题,其中的信息可能已经有所发展或是发生改变。

    这种带时区的时间:2020-10-20T21:26:06.913277863+09:00,如何格式化:%Y:%m:%d %H:%M:%S

    不可影响时间精度

    已经解决了,方法如下:

    import pytz
    from tzlocal import get_localzone
    from dateutil.parser import parse

    my_time = "2020-10-20T21:26:06.913277863+09:00"
    dt = parse(my_time)
    localtime = dt.astimezone(pytz.timezone('{}'.format(get_localzone())))
    print(localtime.strftime("%Y-%m-%d %H:%M:%S"))
    # 2020-10-20 20:26:06

    datetime 默认不带 tzinfo,需要插入
    或者你自己随便写写时区也行

    >>> datetime(2006,1,2,15,4,5,7,tzinfo=timezone(timedelta(hours=8))).strftime("%Y:%m:%dT%H:%M:%S.%f%z")
    '2006:01:02T15:04:05.000007+0800'

    不过 datetime 的精度只到 μs,寻求第三方库或者干脆补三个 0 吧

    之前用 python 处理 MongoDB 里的时间, dateutil 库可以转换
    from dateutil import parser
    parser.parse("2020-10-20T21:26:06.913277863+09:00").strftime("%Y:%m:%d %H:%M:%S")

    时间处理推荐 arrow 库

    >>> import arrow
    >>> a = "2020-10-20T21:26:06.913277863+09:00"
    >>> b = arrow.get(a)
    >>> b
    <Arrow [2020-10-20T21:26:06.913278+09:00]>
    >>> b.format("YYYY-MM-DD hh:mm:ss")
