Python列出了斯堪的纳维亚文字 [英] Python lists with scandinavic letters

问题描述

emacs，unix

输入：

  with open（example.txt，r）as f：
 for f 
打印文件
 split = files.split（）
打印分割
  

输出：

  Hello world 
 ['Hello'，'world'] 
 Hellowörld
 ['Hello'，'w\xf6rld'] 
  

解决方案

Python正在打印字符串表示，其中包含一个不可打印的字节。不可打印的字节（ASCII范围以外的任何字符或控制字符）显示为转义序列。

重点是您可以复制该表示并将其粘贴到Python代码或解释器，产生完全相同的值。

\xf6 转义码表示一个字节十六进制值F6，当被解释为拉丁文-1字节值时，是ö字符。

你可能想要将该值解码为Unicode以一致地处理数据。如果您还不知道Unicode是什么，或者想知道编码的其他内容，请参阅：

Can anyone explain what causes this for better understanding of the environment?

emacs, unix

input:

with open("example.txt", "r") as f:
    for files in f:
        print files
        split = files.split()
        print split

output:

Hello world
['Hello', 'world']
Hello wörld
['Hello', 'w\xf6rld']

解决方案

Python is printing the string representation, which includes a non-printable byte. Non-printable bytes (anything outside the ASCII range or a control character) is displayed as an escape sequence.

The point is that you can copy that representation and paste it into Python code or into the interpreter, producing the exact same value.

The \xf6 escape code represents a byte with hex value F6, which when interpreted as a Latin-1 byte value, is the ö character.

You probably want to decode that value to Unicode to handle the data consistently. If you don't yet know what Unicode really is, or want to know anything else about encodings, see:
