Python 3 AI：检查时间

Question

我正在创建一个人工智能/个人助理/聊天机器人组合。它非常适合聊天和回答我已经输入答案的问题，并且代码相当简单。

但我需要添加一种方式，以便我可以说“现在几点？” （或类似的）并得到回复，告诉我准确的当前时间。这是最重要的，但如果可能的话，我希望它能够检查天气并用作计算器。我会附上我到目前为止所拥有的。 （几乎没有完成，只有大约 15%）。

我正在使用 Python 3。我对 Python 很陌生，并且正在为一个学校项目制作这个，所以请不要对解决方案过于复杂，或者简单地解释一下。另外，重要的是：我将把它放在程序的哪个位置？

代码从这里开始：

Answer 1

您已经完成了很多工作，所以我将就使用 Python 打印当前时间为您提供一些指导，您应该能够将其放入您的程序中，无论您决定它属于什么地方。

要返回您的时区的当前时间（您没有指定您想要的时区），您可以导入 datetime 库并询问它的时间，如下所示：

import datetime
now = datetime.datetime.now()
print(now)

这可能会为您提供您所在时区的时间，一个类似于2016-02-01 16:37:30.591102 的值。

可选的更难的下一步

为了更通用一点，您可以提示用户输入时区偏移量，例如 -8（在加利福尼亚州表示 PST）。最直接的方法之一是在 UTC 中使用以下函数：

now = datetime.datetime.utcnow()

然后你必须添加或减去用户的时区偏移，使用timedelta：

users_now = now + datetime.timedelta(hours=USERS_OFFSET)

当您提示用户输入时区偏移量时，您返回的值将是 str，但您需要它是某种数字才能将其传递给 timedelta 函数。如果你想走这条路，你需要某种方法将字符串转换为数字。

另一个问题是您需要知道用户向您的程序询问了时间问题，因为您必须立即使用时区偏移问题来跟进该问题。

如何以有趣的方式打印日期时间对象

最后，有许多不同的方法来格式化now 给你的值，以便以有趣的方式打印出来。我们经常使用strftime 函数，您可以将其理解为“时间字符串”，我们将其传递给格式化字符串，以便函数知道我们想要的格式。格式化字符串使用特定的标识符，which you can see in the documentation:

print(datetime.datetime.strftime(datetime.datetime.now(), "%H %M %b %d"))

这将打印小时后跟一个空格，然后是分钟，然后是一个空格和月份，作为 3 个字符的缩写，后跟一个空格和日期：

16 44 Feb 01

您可以使用文档中的示例尝试不同的时间格式化方式。

您询问的其他问题

天气和计算器的例子有点复杂：天气，因为您需要从网站请求它并解析结果；而计算器，因为您需要编写一些东西来解析输入并计算出什么与它有关。

我建议使用这些示例来玩弄时间，然后，如果您真的想处理计算器，那么也许可以查看“reverse polish notation”上的内容，这样至少您不必匹配括弧。
