Installation with multiple interpreters

It's possible to analyse code written for older or multiple interpreters by using the py-version option and setting it to the oldest supported interpreter of your code. For example you can check that there are no f-strings in Python 3.5 code using Python 3.8 with an up-to-date pylint even if Python 3.5 is past end of life (EOL) and the version of pylint you use is not compatible with it.

We do not guarantee that py-version will work for all EOL Python interpreters indefinitely, (for anything before Python 3.5, it probably won't). If a newer version does not work for you, the best available pylint might be an old version that works with your old interpreter but without the bug fixes and features of later versions.
