如何在python中获取任何大小的空数组? [英] How do I get an empty array of any size in python?

问题描述

我基本上想在C语言中使用python等效项:

I basically want a python equivalent of this in C:

int a[x];

但是在python中，我声明了一个像这样的数组:

but in python I declare an array like:

a = []

问题是我想给随机槽分配值，例如:

and the problem is I want to assign random slots with values like:

a[4] = 1

但是我无法使用python做到这一点，因为数组为空.

but I can't do that with python, since the array is empty.

推荐答案

如果数组"实际上是一个Python列表，则可以使用

If by "array" you actually mean a Python list, you can use

a = [0] * 10

或

a = [None] * 10
