Capture text around string between 2 characters

Let’s say my full string is this:

blah {something i dont want {sth i want MY STRING blahblah i want } blah

I would like to capture only this part:

{sth i want MY STRING blahblah i want }

Basically anything around and including "MY STRING" until I meet a { and a } on both sides.

I figured it out for the part after MY STRING
with this regex MY STRING.*?(?=})} but I don’t know how to get the first part AKA {sth i want . I tried with some things but all of those get until the first {

>Solution :

That should do the trick:

import re

text = 'blah {something i dont want {sth i want MY STRING blahblah i want } blah'

output = re.findall(r'{[^{]*?MY STRING.*?}', text)[0]
print(output)  # {sth i want MY STRING blahblah i want }

You can test it here.

Explanation:

• {: Matches a parenthesis.
• [^{]: Matches a single character that isn’t {
• *?: Matches the previous character between 0 and unlimited times (lazy).
• MY STRING: Matches MY STRING.
• .*?: Matches any character between 0 and unlimited times (lazy).
• }: Matches a parenthesis.
