factorise split

[enigma619]

Hi

I've general question, not just linked with python (sorry if off topic)

i've a split expression which works:
reason.split(" ")[3].split("(")[2].split(")")[0].split("%")[0]

The expression I want to split is like:
test STATE (64/100)(64%) test1 test2.....

is there any mean to optimize it?

Thanks for help
Alex
