python - Regex: How to find a GUID in a long string?

Question

posted Oct 24, 2021 in Technique[技术] by 深蓝 (71.8m points)

Let's say I have this string:

str = 'something-rows-1973912739821738172-25892e17-80f6-415f-9c65-7395632f0223'

I need to remove GUID part:

25892e17-80f6-415f-9c65-7395632f0223

This is what I've so far but it isn't working:

c = re.compile('[0-9a-f]{12}4[0-9a-f]{3}[89ab][0-9a-f]{15}', re.I)
res = c.match(str)
print(res)

Can anyone please help?

From this answer, you need this:

[0-9a-f]{8}-[0-9a-f]{4}-[1-5][0-9a-f]{3}-[89ab][0-9a-f]{3}-[0-9a-f]{12}
