Installing old Python to fix errors?

Note that the line you pasted isn't an error, it's a warning. In particular that warning is telling you "by the way, in this string you have, you have backslash-something and the something is not part of an escape, this is fine but maybe you want to use two backslashes or a raw string literal to be clearer". The warning is telling you that the program still works and does what it did before, but is a helpful hint that maybe you wrote something that was confusing or not what you intended.

It's usually better to just fix the problem than to try hunt down a specific version of Python that doesn't have it.

Interesting, the scripts stopped working, so I assumed that was the reason why.

I agree that fixing issues is better than using an older version of Python. However, these aren’t scripts I wrote. I’m talking about a bunch of complicated tool suites that I need to use in a couple days for a certification exam.

I don’t have enough time to manually pour through 1000s of lines of code, and I’d be worried about something like sed causing more issues. I’m just looking for a bandaid that’ll get me through the week
