将字符串转换为numpy数组 [英] Convert string to numpy array

问题描述

我有一个像mystr = "100110"这样的字符串(实际大小要大得多)，我想将其转换为像mynumpy = [1, 0, 0, 1, 1, 0], mynumpy.shape = (6,0)这样的numpy数组，我知道numpy具有np.fromstring(mystr, dtype=int, sep='')，但问题是我无法拆分我的字符串到它的每个数字，因此numpy将其视为一个数字.任何想法如何将我的字符串转换为numpy数组?

I have a string like mystr = "100110" (the real size is much bigger) I want to convert it to numpy array like mynumpy = [1, 0, 0, 1, 1, 0], mynumpy.shape = (6,0), I know that numpy has np.fromstring(mystr, dtype=int, sep='') yet the problem is I can't split my string to every digit of it, so numpy takes it as an one number. any idea how to convert my string to numpy array?

推荐答案

list可以帮助您做到这一点.

list may help you do that.

import numpy as np

mystr = "100110"
print np.array(list(mystr))
# ['1' '0' '0' '1' '1' '0']

如果要获取数字而不是字符串:

If you want to get numbers instead of string:

print np.array(list(mystr), dtype=int)
# [1 0 0 1 1 0]
