Python连接字符串-UnicodeDecodeError:'ascii'编解码器无法解码字节

问题描述

我想像这样连接两个字符串:

I want to concatenate two strings like this:

requestData = command + ' ' + data

在我的情况下，数据"包含二进制数据，不应打开该二进制数据，而应将其粘贴到命令中.但是imho python试图打开它，但失败并显示:

"data" in my case holds binary data, that should not be opened - it should just glue it to command. But imho python is attempting to open it and it fails with:

UnicodeDecodeError: 'ascii' codec can't decode byte 0xbc in position 1: ordinal not in range(128)

有没有不打开就可以粘的方法吗?

Is there a way to glue it without opening?

Python 2.7另外，我的数据实际上不是utf-8解码可能没有帮助-它的二进制数据.

Python 2.7Also my data is actualy not utf-8 decode might not help - its binary data.

推荐答案

尝试使用 http://docs.python.org/library/array.html (带有'B')而不是字符串

Try using http://docs.python.org/library/array.html (with 'B') instead of string
