Python: preg_replace function analog

Question

I have a litle expression in PHP:

  $search = array("'<(script|noscript|style|noindex)[^>]*?>.*?</(script|noscript|style|noindex)>'si",
    "'<\!--.*?-->'si",
    "'<[\/\!]*?[^<>]*?>'si",
    "'([\r\n])[\s]+'");

$replace = array ("",
  "",
  " ", 
  "\\1 ");

  $text = preg_replace($search, $replace, $this->pageHtml);

How i did run this on python? re.sub?

@bereal ok, how did i set multiple patterns and replacements to re.sub? — Roman Nazarkin

It doesn't seem to have a special call for that, but why not using '|' as described e.g. here? — bereal

As @bereal commented use the Regular Expression module re.sub.

Here's a simple example

Python:

>>> import re
>>> re.sub(r'([^A-Z])([A-Z])', r'\1_\2', 'camelCase').lower()
'camel_case'

And just for kicks here's it on PHP too:

<?php
echo strtolower(preg_replace('/([^A-Z])([A-Z])/', '$1_$2', 'camelCase'));
// prints camel_case
