Regex help needed!

[Oltmans]

Hello,. everyone.

I've a string that looks something like
----
lksjdfls <div id ='amazon_345343'> kdjff lsdfs </div> sdjfls <div id
=   "amazon_35343433">sdfsd</div><div id='amazon_8898'>welcome</div>
----

>From above string I need the digits within the ID attribute. For
example, required output from above string is
- 35343433
- 345343
- 8898

I've written this regex that's kind of working
re.findall("\w+\s*\W+amazon_(\d+)",str)

but I was just wondering that there might be a better RegEx to do that
same thing. Can you kindly suggest a better/improved Regex. Thank you
in advance.
