Python中的祖鲁模块

Zulu是原生 DateTime 的直接替代品。在此，所有 DateTime 对象都转换为 UTC 并存储为 UTC。 UTC 和时区之间有一个大纲。因此，时区表示仅适用于转换为原始 DateTime。它支持使用 strptime strftime 指令和 Unicode 日期模式的多种字符串格式。

安装

要安装此模块，请在终端中键入以下命令。

pip install zulu

Zulu 模块的类

zulu.Zulu：用于表示不可变 UTC DateTime 对象的 Zulu 类。提供给它的任何时区信息都将从时区转换为 UTC。如果没有给出时区信息，则假定 DateTime 是 UTC 值。所有类型的算术都在 Fundamental UTC DateTime 对象上执行。在这方面，祖鲁没有改变时区的概念。尽管如此，本地化仅在 Zulu 对象被格式化为字符串时才会发生。

函数或类方法

1. now() :- 它以 Zulu 对象的形式返回当前的 UTC 日期和时间。

import zulu
  
  
dt = zulu.now()
print("Today date and time is:", dt)

输出：

Today date and time is: 2020-04-17T16:10:15.708064+00:00
