使用 Python 进行字符转换(如 tr 命令) [英] Character Translation using Python (like the tr command)

问题描述

有没有办法使用 Python 进行字符翻译/音译(有点像 tr 命令)?

Is there a way to do character translation / transliteration (kind of like the tr command) using Python?

Perl 中的一些示例是:

Some examples in Perl would be:

my $string = "some fields";
$string =~ tr/dies/eaid/;
print $string;  # domi failed

$string = 'the cat sat on the mat.';
$string =~ tr/a-z/b/d;
print "$string\n";  # b b   b.  (because option "d" is used to delete characters not replaced)

推荐答案

参见 <代码>string.translate

import string
"abc".translate(string.maketrans("abc", "def")) # => "def"

请注意文档对 unicode 字符串翻译中微妙之处的评论.

Note the doc's comments about subtleties in the translation of unicode strings.

而对于 Python 3，您可以直接使用:

And for Python 3, you can use directly:

"abc".translate(str.maketrans("abc", "def"))

由于 tr 更高级一些，还可以考虑使用 re.sub.

Since tr is a bit more advanced, also consider using re.sub.
