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

问题描述

我基本上想要一个在 C 中的 Python 等价物:

I basically want a python equivalent of this in C:

int a[x];

但在python中我声明了一个数组，如:

but in python I declare an array like:

a = []

问题是我想用以下值分配随机插槽:

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

a[4] = 1

但我不能用 python 来做，因为数组是空的.

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

推荐答案

如果数组"实际上是指 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
