Looping through python regex matches
Python's re.findall should work for you.
import res = "ABC12DEF3G56HIJ7"pattern = re.compile(r'([A-Z]+)([0-9]+)')for (letters, numbers) in re.findall(pattern, s): print(numbers, '*', letters)
It is better to use re.finditer if your dataset is large because that reduces memory consumption (findall() return a list of all results, finditer() finds them one by one).
import res = "ABC12DEF3G56HIJ7"pattern = re.compile(r'([A-Z]+)([0-9]+)')for m in re.finditer(pattern, s): print m.group(2), '*', m.group(1)
