How to convert 'binary string' to normal string in Python3?
提问by Hanfei Sun
For example, I have a string like this(return value of subprocess.check_output):
例如，我有一个这样的字符串（返回值为subprocess.check_output）：
>>> b'a string'
b'a string'
Whatever I did to it, it is always printed with the annoying b'before the string:
无论我对它做了什么，它总是b'在字符串之前打印出烦人的内容：
>>> print(b'a string')
b'a string'
>>> print(str(b'a string'))
b'a string'
Does anyone have any ideas about how to use it as a normal string or convert it into a normal string?
有没有人对如何将其用作普通字符串或将其转换为普通字符串有任何想法？

Decode it.
解码它。
>>> b'a string'.decode('ascii')
'a string'
To get bytes from string, encode it.
要从字符串中获取字节，请对其进行编码。
>>> 'a string'.encode('ascii')
b'a string'
