ISO 时间到人类可读时间 python

Question

我正在使用 Python。我的时间格式是

2020-05-23T06:35:11.418279Z #May 23, 2020 at 12:05:11 PM GMT+05:30

我想转换成人类可读的时间，比如

23-05-2020 12:05 PM

我也试过解析器。但是没有效果。

谁能帮我解决这个问题？

提前致谢:)

Answer 1

另见 How do I parse an ISO 8601-formatted date?

不幸的是，无法使用 built-in fromisoformat (Python 3.7+) due to the Z. You can use strptime instead, or this workaround 或 dateutil 的解析器直接解析“2020-05-23T06:35:11.418279Z”这样的字符串。例如：

from datetime import datetime
import dateutil

s = '2020-05-23T06:35:11.418279Z'

### parsing options
# strptime
dt = datetime.strptime(s, '%Y-%m-%dT%H:%M:%S.%f%z')
# alternatively fromisoformat with replace (most efficient)
dt = datetime.fromisoformat(s.replace('Z', '+00:00'))
# or more convenient and a bit less efficient:
dt = dateutil.parser.isoparse(s)

# change timezone to Indian Standard Time:
dt = dt.astimezone(dateutil.tz.gettz('Asia/Kolkata'))
# datetime.datetime(2020, 5, 23, 12, 5, 11, 418279, tzinfo=tzfile('Asia/Calcutta'))

# note for Python 3.9+:
# use zoneinfo from the standard lib to get timezone objects

# now format to string with desired format
s_out = dt.strftime('%Y-%m-%d %I:%M %p')
s_out
# '2020-05-23 12:05 PM'

Answer 2

import datetime, pytz
isodate = '2020-05-23T06:35:11.418279Z'
d = datetime.datetime.fromisoformat(isodate[:-1]).replace(tzinfo=pytz.utc) # we need to strip 'Z' before parsing
print(d.astimezone(pytz.timezone('Asia/Kolkata')).strftime('%d-%m-%Y %I:%M %p'))
