I don't have a lot of experience with regular expressions, and I'm breaking my head over this one.

I have the following string: (2*8)+(3*3)

I want to retrieve 2*8 and 3*3, but the character between the parentheses can vary,

If i use the following regex: r'\((.*)\)'

I get 2*8)+(3*3

How do I get 2*8 and 3*3?

@SebastianProske This problem smells like maybe it needs a parser, certainly if there could be nested parentheses. – Tim Biegeleisen Aug 15 '17 at 11:43
ah i got a bit further, thank you, but now when i try to match (2*(3*7))+(2+2), it leaves a parentheses behind – Oreborous Aug 15 '17 at 11:44
Use a parser, it will be much more readable – Toto Aug 15 '17 at 11:45
could you direct me to a parser? – Oreborous Aug 15 '17 at 11:46
