Bonjour,

En python ça donnerait ça:

import re

S = ["test1xyz27", "aa9toto000", "x012"]
pattern = r'([a-z]+)([0-9])([a-z]*)([0-9]+)'
for s in S:
  v1, v2, v3, v4 = re.match(pattern, s).groups()
  print(f"v1: {v1}, v2: {v2}, v3: {v3}, v4: {v4}")


v1: test, v2: 1, v3: xyz, v4: 27
v1: aa, v2: 9, v3: toto, v4: 000
v1: x, v2: 0, v3: , v4: 12
