regex: python to get string between parenthesis

Question

I need to fetch text between parenthesis { text } in python. here is my sample string,

my_txt = "/home/admin/test_dir/SAM_8860-fg_frame_{001,002,003,004,005,007}.png"

I need numbers between {}.

I tried,

>>> re.search(r'{.*}',my_txt).group()
'{001,002,003,004,005,007}'

but it returns string along with curly braces.

expected output is, '001,002,003,004,005,007'

how to omit curly braces to fetch string in python regex?

`re.search(r'{.*}',my_txt).group().replace('{', '').replace('}', '')` — Vivek Kalyanarangan, Feb 20 '18 at 09:29
It looks like you're trying to expand the content in the braces, like bash does. If that's the case, [there exists a package for that](https://github.com/trendels/braceexpand) — Nils Werner, Feb 20 '18 at 09:30
Use lookbehind and lookahead: `re.findall('(?<={).+?(?=})',my_txt)` — Jongware, Feb 20 '18 at 09:32
@WiktorStribiżew thanks for your comment it works as expected. and thanks for downvote — Mohideen bin Mohammed, Feb 20 '18 at 09:32

Get only the matched group:

>>> re.search(r'{(.*?)}',my_txt).group(1)
'001,002,003,004,005,007'

Try this. it creates group and select 1st group

re.search(r'{(.*?)}',my_txt).group(1)
