如何在Python(给定perl脚本)中用ASCII字符替换unicode字符? [英] How to replace unicode characters by ascii characters in Python (perl script given)?
问题描述
我正在尝试学习python,却不知道如何将以下perl脚本转换为python:
I am trying to learn python and couldn't figure out how to translate the following perl script to python:
#!/usr/bin/perl -w
use open qw(:std :utf8);
while(<>) {
s/\x{00E4}/ae/;
s/\x{00F6}/oe/;
s/\x{00FC}/ue/;
print;
}
该脚本仅将Unicode变音符更改为替代的ascii输出. (所以完整的输出是ascii.)对于任何提示,我将不胜感激.谢谢!
The script just changes unicode umlauts to alternative ascii output. (So the complete output is in ascii.) I would be grateful for any hints. Thanks!
推荐答案
- 使用
fileinput
模块循环遍历标准输入或文件列表, - 将您从UTF-8读取的行解码为unicode对象
- 然后使用
translate
方法 - Use the
fileinput
module to loop over standard input or a list of files, - decode the lines you read from UTF-8 to unicode objects
- then map any unicode characters you desire with the
translate
method
translit.py
看起来像这样:
#!/usr/bin/env python2.6
# -*- coding: utf-8 -*-
import fileinput
table = {
0xe4: u'ae',
ord(u'ö'): u'oe',
ord(u'ü'): u'ue',
ord(u'ß'): None,
}
for line in fileinput.input():
s = line.decode('utf8')
print s.translate(table),
您可以这样使用它:
$ cat utf8.txt
sömé täßt
sömé täßt
sömé täßt
$ ./translit.py utf8.txt
soemé taet
soemé taet
soemé taet
- 更新:
如果您使用的是python 3字符串,则默认情况下是unicode,并且如果它包含非ASCII字符甚至是非拉丁字符,则不需要对其进行编码.因此,解决方案如下所示:
In case you are using python 3 strings are by default unicode and you dont' need to encode it if it contains non-ASCII characters or even a non-Latin characters. So the solution will look as follow:
line = 'Verhältnismäßigkeit, Möglichkeit'
table = {
ord('ä'): 'ae',
ord('ö'): 'oe',
ord('ü'): 'ue',
ord('ß'): 'ss',
}
line.translate(table)
>>> 'Verhaeltnismaessigkeit, Moeglichkeit'
