我可以在打印声明中摆脱这个“ b”字符​​吗？ [英] Can I get rid of this 'b' character in my print statement?

问题描述

我想知道 b 这个字符是什么以及为什么它出现。我还想知道在打印数组时是否可以摆脱它？

I'm wondering what this b charcter is and why it's appearing. I'm also wondering if I can get rid of it while printing the array?

这是我的示例：

arr1 = np.array(['1', '2'], dtype = 'c')
print("array:", arr1, "and its dtype is: ", arr1.dtype)

这是输出：

array: [b'1' b'2'] and its dtype is:  |S1

推荐答案

这意味着字节字面量：

要摆脱它，您可以尝试输出为字符串而不是数组对象

As to getting rid of it you might try outputting as string rather than as an array object

例如：

s="["
for x in arr1:
    s += x.decode('utf-8')   
s+= "]"

print ("array: ", s , " and it's dtype is: ", arr1.dtype");
