[英]how to convert 2d list to 2d native python array not numpy array?
I want to convert python 2d list, 我想转换python 2d列表,
[[1,2,3],[4,5,6]]
to 至
python3 array.array
type, python3
array.array
类型,
[ [1 2 3]
[4 5 6] ]
The most important challenge is I wont import numpy
. 最重要的挑战是我不会导入
numpy
。 So I cant use np.asarray()
. 所以我不能使用
np.asarray()
。
I have also used array.fromlist()
and array.extend()
. 我还使用了
array.fromlist()
和array.extend()
。 Both methods are creating an array of single dimension. 这两种方法都在创建单维数组。 But I want to convert multi dimension list to multi dimension array.
但我想将多维列表转换为多维数组。 Is there any way?
有什么办法吗?
What you're asking is not possible. 你问的是不可能的。 From the
array
docs : 从
array
文档 :
This module defines an object type which can compactly represent an array of basic values: characters, integers, floating point numbers ... The type is specified at object creation time by using a type code
该模块定义了一个对象类型,它可以紧凑地表示一个基本值数组:字符,整数,浮点数......通过使用类型代码在对象创建时指定类型
The only supported types are as follows (notice the absence of list
): 唯一支持的类型如下(注意缺少
list
):
Type code C Type Python Type
'b' signed char int
'B' unsigned char int
'u' Py_UNICODE Unicode character
'h' signed short int
'H' unsigned short int
'i' signed int int
'I' unsigned int int
'l' signed long int
'L' unsigned long int
'q' signed long long int
'Q' unsigned long long int
'f' float float
'd' double float
It seems like you might be confusing the array
module, with a native implementation of numpy
arrays. 看起来你可能会混淆
array
模块,使用numpy
数组的本机实现。 This is not the case . 事实并非如此 。
