'str'对象在Python3中没有属性'decode'

I've some problem with "decode" method in python 3.3.4. This is my code:

我在python 3.3.4中使用“decode”方法遇到了一些问题。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:

但是我无法解决这个问题：

AttributeError: 'str' object has no attribute 'decode'

Do you have any ideas? Thanks

你有什么想法？谢谢

One encodes strings, and one decodes bytes.

一个编码字符串，一个解码字节。

You should read bytes from the file and decode them:

您应该从文件中读取字节并解码它们：

for lines in open('file','rb'):
    decodedLine = lines.decode('ISO-8859-1')
    line = decodedLine.split('\t')

Luckily open has an encoding argument which makes this easy:

幸运的是，open有一个编码参数，这使得这很简单：

for decodedLine in open('file', 'r', encoding='ISO-8859-1'):
    line = decodedLine.split('\t')

open already 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'.

如果在文本模式下打开，open已经在Python 3中解码为Unicode。如果要将其作为字节打开，以便可以解码，则需要使用模式'rb'打开。

This works for me smoothly to read Chinese text in Python 3.6. First, convert str to bytes, and then decode them.

这对我来说非常适合在Python 3.6中阅读中文文本。首先，将str转换为字节，然后解码它们。

for l in open('chinese2.txt','rb'):
    decodedLine = l.decode('gb2312')
    print(decodedLine)
