numpy bytes to plain string
提问by V.K.
I have a numpy array Xwith dtype 'S' (numpy.bytes_). For example printing print(X[0, 0])yields b'somestring'. Similarly str(X[0, 0])returns string "b'somestring'".
我有一个numpy的阵列X有dtype 'S' (numpy.bytes_)。例如印刷print(X[0, 0])产量b'somestring'。同样str(X[0, 0])返回 string "b'somestring'"。
However I need to print or convert to string so that it does not contain b'at the beginning and 'at the end. I just want to print somestringor return a string "somestring". How to do it?
但是我需要打印或转换为字符串，以便它b'在开头和'结尾不包含。我只想打印somestring或返回一个 string "somestring"。怎么做？
Note: I cannot change the type of the array.
注意：我无法更改数组的类型。

You just need to decode the string back into ASCII, so it would just be:
你只需要将字符串解码回 ASCII，所以它只是：
bytes_string.decode('UTF-8')
Demo:
演示：
>>> b'somestring'.decode('UTF-8')
'somestring'
