Python replacement for PHP's strtr [ edit | history ]
Python 2.x:
import string
result = myStr.translate(string.maketrans(from, to))


Python 3.x:
result = myStr.translate(str.maketrans(from, to))

result = myStr.translate(str.maketrans(replace_dict))


Caveat: these solutions only cover the first use case of strtr(): plain character substitution. It does not implement the second case: array tokens.

Examples

Example #1 strtr() example

<?php
$addr 
strtr($addr"äåö""aao");
?>

strtr() may be called with only two arguments. If called with two arguments it behaves in a new way: from then has to be an array that contains string -> string pairs that will be replaced in the source string. strtr() will always look for the longest possible match first and will *NOT* try to replace stuff that it has already worked on.

Example #2 strtr() example with two arguments

<?php
$trans 
= array("hello" => "hi""hi" => "hello");
echo 
strtr("hi all, I said hello"$trans);
?>

The above example will output:

hello all, I said hi
