如何将 Python 3 字节字符串变量转换为常规字符串? [英] How do I convert a Python 3 byte-string variable into a regular string?

问题描述

我已经阅读了一个 XML 电子邮件附件

bytes_string=part.get_payload(decode=False)

正如我的变量名称所暗示的那样，有效载荷以字节字符串的形式出现.

我正在尝试使用推荐的 Python 3 方法将此字符串转换为我可以操作的可用字符串.

示例显示:

<块引用>

str(b'abc','utf-8')

如何将 b(字节)关键字参数应用于我的变量 bytes_string 并使用推荐的方法?

我尝试的方法不起作用:

str(bbytes_string, 'utf-8')

解决方案

你在最后一行几乎正确.你想要

str(bytes_string, 'utf-8')

因为bytes_string的类型是bytes，与b'abc'的类型相同.

I have read in an XML email attachment with

bytes_string=part.get_payload(decode=False)

The payload comes in as a byte string, as my variable name suggests.

I am trying to use the recommended Python 3 approach to turn this string into a usable string that I can manipulate.

The example shows:

str(b'abc','utf-8')

How can I apply the b (bytes) keyword argument to my variable bytes_string and use the recommended approach?

The way I tried doesn't work:

str(bbytes_string, 'utf-8')

解决方案

You had it nearly right in the last line. You want

str(bytes_string, 'utf-8')

because the type of bytes_string is bytes, the same as the type of b'abc'.
