Please support regex for version number (digits and dots) from a string

[Tecuma]

Hello Community,

I have the following string

"SYS"."M_SYSTEM_OVERVIEW" ('System', 'Version', '', '2.00.050.00.1592305219 (fa/hana2sp05)')

I need the version information

2.00.050.00.1592305219

from that string.

I tried several things via regex but all failed. One of my ideas was to use the first part until the version number as a own group.

m = re.search('("SYS"."M_SYSTEM_OVERVIEW" \(\'System\', \'Version\', \'\', \')(\S+)(.+)', line)
Version =  m.group(2)

This lead to an AttributeError: 'NoneType' object has no attribute 'group'
How should I design patterns to get this?
Also I am not sure when to escape in that string and when not.

Can someone please assist.

Regards
