Combining two patterns with named capturing group in Python?

Question

I have a regular expression which uses the before pattern like so:

>>> RE_SID = re.compile(r'(?P<sid>(?<=sid:)([A-Za-z0-9]+))')
>>> x = RE_SID.search('sid:I118uailfriedx151201005423521">>')
>>> x.group('sid')
'I118uailfriedx151201005423521'

and another like so:

>>> RE_SID = re.compile(r'(?P<sid>(?<=sid:<<")([A-Za-z0-9]+))')
>>> x = RE_SID.search('sid:<<"I118uailfriedx151201005423521')
>>> x.group('sid')
'I118uailfriedx151201005423521'

How can I combine these two patterns in a way that, after parsing these two different lines,:

sid:A111uancalual2626x151130185758596
sid:<<"I118uailfriedx151201005423521">>

returns only the corresponding id to me.

Answer 1

RE_SID = re.compile(r'sid:(<<")?(?P<sid>([A-Za-z0-9]+))')

Use this, I've just tested and it is working for me. I've moved some part out.
