提问by hasmet
I've some problem with "decode" method in python 3.3.4. This is my code:
我在 python 3.3.4 中的“解码”方法有一些问题。这是我的代码：
for lines in open('file','r'):
decodedLine = lines.decode('ISO-8859-1')
line = decodedLine.split('\t')
But I can't decode the line for this problem:
但我无法解码此问题的行：
AttributeError: 'str' object has no attribute 'decode'
Do you have any ideas? Thanks
你有什么想法？谢谢

One encodesstrings, and one decodesbytes.
一种编码字符串，一种解码字节。
You should read bytes from the file and decode them:
您应该从文件中读取字节并对其进行解码：
for lines in open('file','rb'):
decodedLine = lines.decode('ISO-8859-1')
line = decodedLine.split('\t')
Luckily openhas an encoding argument which makes this easy:
幸运的是，open有一个编码参数可以让这变得简单：
for decodedLine in open('file', 'r', encoding='ISO-8859-1'):
line = decodedLine.split('\t')

openalready decodes to Unicode in Python 3 if you open in text mode. If you want to open it as bytes, so that you can then decode, you need to open with mode 'rb'.
open如果您以文本模式打开，则已经在 Python 3 中解码为 Unicode。如果你想以字节的形式打开它，这样你就可以解码，你需要用'rb'模式打开。

This works for me smoothly to read Chinese text in Python 3.6. First, convert str to bytes, and then decode them.
这对我在 Python 3.6 中顺利阅读中文文本很有效。首先，将 str 转换为字节，然后对其进行解码。
for l in open('chinese2.txt','rb'):
decodedLine = l.decode('gb2312')
print(decodedLine)
