Summary

Fixes three SyntaxWarning messages emitted by Python 3.12+ in plc4py/drivers/umas/UmasTag.py:

  1. Invalid escape sequence \[ in the regex _ADDRESS_PATTERN — converted the string literal to a raw string.
  2. Two occurrences of len(...) is not 0 — replaced with != 0. Comparing int with is/is not is unreliable (works only by CPython small-int caching) and the behavior is deprecated.

Test plan

  • pytest passes (77 passed, 36 xfailed — same as before, now with 0 warnings)
  • No behavioral changes — both fixes are semantics-preserving

- Use raw string for regex pattern (fixes invalid escape sequence '\[')
- Replace 'is not 0' with '!= 0' for int comparison
