regex: extracting alphanumeric sequences delimited by a "-" (minus) character

Question

String:

text = '<script src="https://mytest.com/abcdefg12-hijklmno34.js"></script>'

I'd like to extract these two alphanumeric values delimited by "-":

regex = '??????'
m = re.split(regex, text)    
print(m)

desired output output:

[
'abcdefg12',
'hijklmno34
]

What's the most elegant regex should I be using for this?

You could use `r'/([a-z\d.]+)-([a-z\d.]+)(?=[^.])` with the case-indifferent flag set. [ref](https://regex101.com/r/kBnZR9/1/) — Cary Swoveland, Jul 15 '20 at 00:35

Try this:

myarray = re.compile('\w+(?=-)|(?<=-)\w+').findall(text)

@bigbounty not bad for a java guy, eh? :) – Bohemian Jul 14 '20 at 23:19
Haha, yeah. Learning from you guys – bigbounty Jul 14 '20 at 23:19
What about `mytest.com/abcdefg12-/abc/-hijklmno34.js`? – Cary Swoveland Jul 14 '20 at 23:40
do you think this pattern will work `/(?=\w+\-\w+)(\w+)|(?<=\w\-)(\w+)/` – Sven.hig Jul 14 '20 at 23:51
@CarySwoveland what about it? this regex suits OP's purpose well. your example is out of scope. – Bohemian Jul 15 '20 at 01:36

@Sven.hig yes, and your regex more precisely fits the example input. – Bohemian Jul 15 '20 at 01:38

In [54]: text = '<script src="https://mytest.com/abcdefg12-hijklmno34.js"></script>'

In [55]: m = re.search("com\/(.*)\.", text)

In [56]: m[1]
Out[56]: 'abcdefg12-hijklmno34'

In [57]: m[1].split("-")
Out[57]: ['abcdefg12', 'hijklmno34']

You could try this pattern /(?=\w+\-\w+)(\w+)|(?<=\w\-)(\w+)/g
