Subject: [PATCH] Numeration in format string and spaces to tab

Old python versions can fall in `ValueError` exception with current string format:
```
$ python
Python 2.6.6 (r266:84292, Jun 14 2019, 09:43:27)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-23)] on linux2

>>> import re
>>> model = 'Z1Z3XMHGST4000NM0033-9ZM170 GA0A'
>>> m = re.match(r'(\w{8})(ST\w+)(?:-(\w{6}))?(?:\s+(\w+))', model)
>>> '{}-{} {} {}'.format(m.group(2), m.group(3), m.group(4), m.group(1))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: zero length field name in format
>>> m.group(2)
'ST4000NM0033'
>>> m.group(3)
'9ZM170'
>>> m.group(4)
'GA0A'
>>> m.group(1)
'Z1Z3XMHG'
```
Also corrected spaces to tabs.
