I was looking for something similar to Python's re.findall()/finditer()

couldn't find anything in
:help function-list
The general intent would be to take an input string and return a
List containing all the sub-strings matching a pattern like
let matches=findall('amwenxipyuqz', '[aeiou]')
would set matches to
['aw', 'en', 'ip', 'uq']
I was able to cobble together a hack-job in this case, but I'd hoped
to be able to do something like
:let a=[] | g/#\w\+/call extend(a, findall(getline('.'), @/))
Does such a function exist and I just missed it?
Thanks!

[Retrying.. as my first attempt to post did not seem to go anywhere.
Apologies if this is a repeat]
It looks like substitute() is the closest to what you want to achieve.
Perhaps you can add submatch() to get the result appended to the list.
Something like this in mind:
:let a=[]|g/#\w\+/call substitute(getline('.'), @/, '\=extend(a,
[submatch(0)])', 'g')
