I am in need of some help to extract a string from the 2nd and 3rd space using pure regex and without splitting the string using library functions.

12301: 0.355940, 0.355940 avg loss, 0.000333 rate, 11.141783 seconds, 787264 images

I want the output to be:

0.355940

I have tried the following regex to extract from the second comma to the avg but failed quite badly.

,[^avg]*

`text.split(',')[1].strip().split(" ")[0].strip()` would still work, just in case you change your mind. As for a regex, extracting text between two strings is a long solved issue. – Wiktor Stribiżew Feb 04 '20 at 10:13

`re.search('([^ ]*) avg', ).groups()[0]` – Corentin Limier Feb 04 '20 at 10:14
