So I have a URL for a video file, and there is a simple hack I can do to get the audio file where I need to edit the string in a certain way.
Here is the starting string:
https://v.redd.it/jvjih3f894b61/DASH_1080.mp4?source=fallback
I need replace the resolution DASH_1080
to DASH_audio
and I figured I could just replace everything between the _
after DASH
and the .
before .mp4
but there are multiple occurrences of .
so using string.partition
would not work.
The URL should look like this:
https://v.redd.it/jvjih3f894b61/DASH_audio.mp4?source=fallback
How could I do this, preferably without regex but I understand it might be the only way.
Thank you.

>>> s = 'https://v.redd.it/jvjih3f894b61/DASH_1080.mp4?source=fallback' >>> re.sub('DASH_d+', 'DASH_audio', s) 'https://v.redd.it/jvjih3f894b61/DASH_audio.mp4?source=fallback'
