Question

I would like to as a basic Python regular expression problem.
I have a dataset

line = "(1,2) (2,3)" 

That can repeat many times so line can also be

line = "(1,2) (3,4) (6,5)"

I have a regular expression

rx = "(\(\s*\d+\s*,\s*\d+\s*\)\s*){2,}$"

I want

a = re.match(rx,line).groups();

to match

('(1,2)','(3,4)'...)

But I can only match the last (6,5). I need the last $ because I don’t know how many bracketed inputs I can have, otherwise an incorrect input such as

(1,2),(3,4),(5,6

will pass the regexp.

any tips?

Edit:
Added the fact that the data was not exactly formatted as detailed. Instead

line= 'blah(1,2) (2,3)blah'

So indeed regular expressions are needed

Thanks

Answer 1

If you really want to use regular expressions (I’m not a regex specialist, but it worked with the given data):

r = "[\(\d+,\d+\)]{1,}"
c = re.findall(r,line)

or else follow nightcracker’s excellent suggestion. Most often the simplest answer is the better answer.
