I'm working on a Python project to find into specified strings like:
< url: 'something', uid: 'something', type: 'something' >
and i need to get the values something. Example:
String value = "url: 'abs52fs', uid: '1fg23s4', type: 'fgh54e'"
re.search("url: '(.*)', uid: '(.*)', type: '(.*)'", value)
OUTPUT: >> [abs52fs, 1fg23s4, fgh54e]
I thought to write a regular expression but it returns a NoneType Object.
Can you help me?

If you don't mind 3 separate calls:
>>> import re
>>> value = "url: 'abs52fs', uid: '1fg23s4', type: 'fgh54e'"
>>> url = re.search(r"url:\s'(.*?)'", value)
>>> url.group(1)
'abs52fs'
>>> uid = re.search(r"uid:\s'(.*?)'", value)
>>> uid.group(1)
'1fg23s4'
>>> type = re.search(r"type:\s'(.*?)'", value)
>>> type.group(1)
'fgh54e'
If you know your data will always follow the pattern url, followed by uid, followed by type, then you can do:
>>> tokens = re.search(r"url:\s'(.*?)',\suid:\s'(.*?)',\stype:\s'(.*?)'", value)
>>> url, uid, type = tokens.groups()
>>> url
'abs52fs'
>>> uid
'1fg23s4'
>>> type
'fgh54e'
Your regular expression works, but it has a problem. It will wrongly accept strings like this:
url: 'abs52fs', url: 'abs52fs', uid: '1fg23s4', type: 'fgh54e'
(see https://regex101.com/r/sK0vN1/1)
Try something like this (https://regex101.com/r/xN7zR0/1):
url: '([^']*)', uid: '([^']*)', type: '([^']*)'
