Extracting Version Number from a String

[britesc]

Hi,
I would like to be able to extract the version number (nimbers and ,) from a string.
I can get the result but only if I use 1 type of delimeter
I have noticed that sometimes the delimeter changes so would like to have multiple delimeters options.
For example

import re
text = 'mawk/kinetic,now 1.3.4.20200120-3.1 amd64 [installed,automatic]'
m = re.search(',now (.+?)-', text)

print(m) 

Output:
<re.Match object; span=(12, 32), match=',now 1.3.4.20200120-'>

print(m.group(0) 

Output:
,now 1.3.4.20200120-

print(m.group(1))

Output:
1.3.4.20200120

In this case m.group(0) contains the answer I need as the delimiter was - but sometimes it can be a + or : as the final delimeter
Equally the first delimeter might be ,now 1:

For info the string is generated by apt list --installed | grep -i mawk (in this case)

So I am getting in a bit of a pickle as I know I should be able to have multiple start delimeters and multiple end delimters,
I assume there must be a simpler way of doing this rather than a series of if statements searching to see what is the start and end delimeter in a string and then calling the correct re.search code.
Regex is really powerfull and a language unto itself but I've not got much spare capacity in my onbaord mental ROM anymore.
Any advice gratefully received.
Thanks and kind regards,
jB

Please, use proper tags when post code, traceback, output, etc. This time I have added tags for you.
See BBcode help for more info.

Then you should use:

m = re.search(',now (.+?)[-+:]', text)

Does that give the results you need?

Sorry for the delayed response. Not very well.
I have managed to use your code with a bit extra to achieve what I required.
Thank you very much.
