How do I update the settings so that when I make a repl I can use version 2.7 of python and not the newest version?
If you have code from Visual Studio or something that you last edited 5 years ago it should be able to translate fairly easily into python 3 because I don't think the syntax really changes but the only things that will are like the
print() function and a couple of other things that if you searched up you could probably find translations for. Or if you really want to use python 2.7 just create a python 2.7 repl but python 2.7 is like ancient history and I would highly recommend not using it due to the reasons @xfinnbar said.
I hope this helps(if it does click the checkmark next to the upvote button so people will know this question is answered)
Create a repl with Python 2.7 as the language, it's listed separately there.
I can warn you, Python 2.7 is not recommended as it will not receive performance updates, bug fixes and new content. Please don't use it unless you really have to.
