You can list all the available timezones with pytz.all_timezones:

您可以列出所有可用的时区pytz.all_timezones：

In [40]: import pytz
In [41]: pytz.all_timezones
Out[42]: 
['Africa/Abidjan',
 'Africa/Accra',
 'Africa/Addis_Ababa',
 ...]

There is also pytz.common_timezones:

还有pytz.common_timezones：

In [45]: len(pytz.common_timezones)
Out[45]: 403

In [46]: len(pytz.all_timezones)
Out[46]: 563

回答by Lennart Regebro

The timezone name is the only reliable way to specify the timezone.

时区名称是指定时区的唯一可靠方法。

You can find a list of timezone names here: http://en.wikipedia.org/wiki/List_of_tz_database_time_zonesNote that this list contains a lot of alias names, such as US/Eastern for the timezone that is properly called America/New_York.

您可以在此处找到时区名称列表：http: //en.wikipedia.org/wiki/List_of_tz_database_time_zones请注意，此列表包含许多别名，例如 US/Eastern 表示正确称为 America/New_York 的时区。

If you programatically want to create this list from the zoneinfo database you can compile it from the zone.tab file in the zoneinfo database. I don't think pytz has an API to get them, and I also don't think it would be very useful.

如果您想以编程方式从 zoneinfo 数据库创建此列表，您可以从 zoneinfo 数据库中的 zone.tab 文件编译它。我不认为 pytz 有一个 API 来获取它们，我也不认为它会很有用。

They appear to be populated by the tz database time zonesfound here.

它们似乎由此处找到的tz 数据库时区填充。

In my opinion this is a design flaw of pytz library. It should be more reliable to specify a timezone using the offset, e.g.

在我看来，这是 pytz 库的设计缺陷。使用偏移量指定时区应该更可靠，例如

pytz.construct("UTC-07:00")

which gives you Canada/Pacific timezone.

这为您提供了加拿大/太平洋时区。

回答by chribsen

Don't create your own list- pytzhas a built-in set:

不要创建自己的列表-pytz有一个内置集：

import pytz
set(pytz.all_timezones_set)  
>>> {'Europe/Vienna', 'America/New_York', 'America/Argentina/Salta',..}

You can then apply a timezone:

然后您可以应用时区：

import datetime
tz = pytz.timezone('Pacific/Johnston')
ct = datetime.datetime.now(tz=tz)
>>> ct.isoformat()
2017-01-13T11:29:22.601991-05:00

Or if you already have a datetimeobjectthat is TZ aware(not naive):

或者，如果您已经有一个datetime可以识别 TZ的对象（不是幼稚的）：

# This timestamp is in UTC
my_ct = datetime.datetime.now(tz=pytz.UTC)

# Now convert it to another timezone
new_ct = my_ct.astimezone(tz)
>>> new_ct.isoformat()
2017-01-13T11:29:22.601991-05:00

EDIT: I would appreciate it if you do not downvote this answer further.This answer is wrong, but I would rather retain it as a historical note. While it is arguable whether the pytz interface is error-prone, it can do things that dateutil.tz cannot do, especially regarding daylight-saving in the past or in the future. I have honestly recorded my experience in an article "Time zones in Python".

编辑：如果您不进一步否决此答案，我将不胜感激。这个答案是错误的，但我宁愿将其保留为历史记录。虽然 pytz 接口是否容易出错是有争议的，但它可以做 dateutil.tz 不能做的事情，特别是关于过去或未来的夏令时。我在一篇文章“Python 中的时区”中诚实地记录了我的经验。

If you are on a Unix-like platform, I would suggest you avoid pytz and look just at /usr/share/zoneinfo. dateutil.tz can utilize the information there.

如果您在类 Unix 平台上，我建议您避免使用 pytz 并查看 /usr/share/zoneinfo。dateutil.tz 可以利用那里的信息。

The following piece of code shows the problem pytz can give. I was shocked when I first found it out. (Interestingly enough, the pytz installed by yum on CentOS 7 does not exhibit this problem.)

下面的一段代码显示了 pytz 可以给出的问题。当我第一次发现它时，我很震惊。（有趣的是，在 CentOS 7 上 yum 安装的 pytz 并没有出现这个问题。）

import pytz
import dateutil.tz
from datetime import datetime
print((datetime(2017,2,13,14,29,29, tzinfo=pytz.timezone('Asia/Shanghai'))
     - datetime(2017,2,13,14,29,29, tzinfo=pytz.timezone('UTC')))
     .total_seconds())
print((datetime(2017,2,13,14,29,29, tzinfo=dateutil.tz.gettz('Asia/Shanghai'))
     - datetime(2017,2,13,14,29,29, tzinfo=dateutil.tz.tzutc()))
     .total_seconds())

-29160.0
-28800.0

I.e. the timezone created by pytz is for the true local time, instead of the standard local time people observe. Shanghai conforms to +0800, not +0806 as suggested by pytz:

即由 pytz 创建的时区是真正的当地时间，而不是人们观察到的标准当地时间。上海符合 +0800，而不是 pytz 建议的 +0806：

pytz.timezone('Asia/Shanghai')
<DstTzInfo 'Asia/Shanghai' LMT+8:06:00 STD>

EDIT:Thanks to Mark Ransom's comment and downvote, now I know I am using pytz the wrong way. In summary, you are not supposed to pass the result of pytz.timezone(…)to datetime, but should pass the datetimeto its localizemethod.

编辑：感谢 Mark Ransom 的评论和投反对票，现在我知道我以错误的方式使用 pytz。总之，你不应该通过的结果pytz.timezone(…)来datetime，但应该通过datetime它的localize方法。

Despite his argument (and my bad for not reading the pytz documentation more carefully), I am going to keep this answer. I was answering the question in one way (how to enumerate the supported timezones, though not with pytz), because I believed pytz did not provide a correct solution. Though my belief was wrong, this answer is still providing some information, IMHO, which is potentially useful to people interested in this question. Pytz's correctway of doing things is counter-intuitive. Heck, if the tzinfocreated by pytz should not be directly used by datetime, it should be a different type. The pytz interface is simply badly designed. The link provided by Mark shows that many people, not just me, have been misled by the pytz interface.

尽管有他的论点（以及我没有更仔细地阅读 pytz 文档的坏处），我还是会保留这个答案。我正在以一种方式回答这个问题（如何枚举支持的时区，尽管不是使用 pytz），因为我认为 pytz 没有提供正确的解决方案。虽然我的信念是错误的，但这个答案仍然提供了一些信息，恕我直言，这对对此问题感兴趣的人可能有用。Pytz 的正确做事方式是违反直觉的。哎呀，如果pytz 创建的tzinfo不应该被 直接使用datetime，它应该是不同的类型。pytz 界面的设计很糟糕。Mark提供的链接显示，很多人，不仅仅是我，都被pytz界面误导了。
