Regex replacement of hyphens?

Question

I am using a language where the syntax is regex_replace(string, pattern, replacement_string).

I have a few strings which look like this s=123-21785-15643411.

I am looking for a pattern to replace s with 1232178515643411.

What would be the pattern such that I can do regex_replace(s, pattern, '') and remove the hyphens from my string?

There is only one flavor where `-` must be escaped - Lua. But those are not regular expressions, Lua uses so called Lua patterns. — Wiktor Stribiżew, Jul 15 '20 at 17:58
Doesn't need a regex, use a string replace method if possible. — , Jul 15 '20 at 18:00

Example could be like:

s="123-21785-15643411";

s = s.replace(/-/g,"");

console.log(s);

In Python 3:

import re
s = "123-21785-15643411"
regex = r"-"
res = re.sub(regex, '', s)
print(res)

Returns:

1232178515643411

but string methods are much more direct:

print(s.replace('-', ''))

Giving the same result
