How to extract text from another text?

Question

Python

I am making a parser on VPN ShadowSocks.
It is necessary to extract the keys themselves from the messages
. Example:

(Какой-то текст) ss://Y2hhY2hhMjAtaWV0Zi1wb2x5MTMwNTpUZXN0UGFzc3dvcmRAdGVzdC5hZGRyZXNzOjc3Nzc=#TestName (Какой-то текст) 
ss://Y2hhY2hhMjAtaWV0Zi1wb2x5MTMwNTpUZXN0UGFzc3dvcmRAdGVzdC5hZGRyZXNzOjc3Nzc=#TestName (Какой-то текст)

From here you need to pull out all two keys into a list. The keys all start with ss:// and end with #, =, or a space

Answer 1

There are at least two ways to solve it:
The first way is to split the lines according to the initial fragment, we get several pieces. We discard the first piece, split the rest along the final fragment and leave the first piece from each - these will be the keys.
The second way is to use regex with the findall method, with a pattern like this:

/(ss:\/\/[a-zA-Z0-9]+=#)/gm
