Python Question

Looping through python regex matches

This has to be easier than what I am running into. My problem is turning a string that looks like this:



12 * ABC
3 * DEF
56 * G
7 * HIJ

And I can't, for the life of me, design a correct set of loops using REGEX matching. The crux of the issue is that the code has to be completely general because I cannot assume how long the
fragments will be, nor how long the
fragments will be.

Thank you for any assistance!

Python's re.findall should work for you.

import re

s = "ABC12DEF3G56HIJ7"
pattern = re.compile(r'([A-Z]+)([0-9]+)')

for (letters, numbers) in re.findall(pattern, s):
    print numbers, '*', letters
