How do I declare an array in Python ?

(如何在Python中声明数组？)

I can't find any reference to arrays in the documentation.

(我在文档中找不到任何对数组的引用。)

Answer 1

variable = []

Now variable refers to an empty list ^* .

(现在variable引用空列表^* 。)

Of course this is an assignment, not a declaration.

(当然这是一项任务，而非宣言。)

There's no way to say in Python "this variable should never refer to anything other than a list", since Python is dynamically typed.

(在Python中没有办法说“这个变量永远不应该引用除列表之外的任何东西”，因为Python是动态类型的。)

^* The default built-in Python type is called a list , not an array.

(^*默认的内置Python类型称为列表 ，而不是数组。)

It is an ordered container of arbitrary length that can hold a heterogenous collection of objects (their types do not matter and can be freely mixed).

(它是一个任意长度的有序容器，可以容纳异质的对象集合（它们的类型无关紧要，可以自由混合）。)

This should not be confused with the array module , which offers a type closer to the C array type;

(这不应该与array模块混淆， array模块提供更接近C array类型的类型;)

the contents must be homogenous (all of the same type), but the length is still dynamic.

(内容必须是同质的（所有相同的类型），但长度仍然是动态的。)
