Numpy：创建随机字符串并制作统一(Numpy: create random strings and make uniform)

Numpy：创建随机字符串并制作统一(Numpy: create random strings and make uniform)

我试过以下代码：

import numpy as np let = ['A', 'B', 'C', 'D'] print(np.random.choice(let, 8, p=[0.25, 0.25, 0.25, 0.25]))

输出：

['A' 'B' 'C' 'A' 'A' 'C' 'A' 'A']

它应该是随机的，但我想要以下输出：25％A，25％，B，25％C，25％D。如下所示：

['A' 'B' 'C' 'A' 'C' 'D' 'D' 'B']

我错过了什么？

I have tried the following code:

import numpy as np let = ['A', 'B', 'C', 'D'] print(np.random.choice(let, 8, p=[0.25, 0.25, 0.25, 0.25]))

output:

['A' 'B' 'C' 'A' 'A' 'C' 'A' 'A']

It should be random but I want the following output: 25% A, 25%, B, 25% C, 25% D. Something like the following:

['A' 'B' 'C' 'A' 'C' 'D' 'D' 'B']

What am I missing?

Per RedEyed评论：

import numpy as np let = ['A', 'B', 'C', 'D'] print(np.random.permutation(let*4))

Per RedEyed comment:

import numpy as np let = ['A', 'B', 'C', 'D'] print(np.random.permutation(let*4))
