Ideally, you’d want to be able to write literals in your language’s natural encoding. You could then edit Python source code with your favorite editor which would display the accented characters naturally, and have the right characters used at runtime. Python supports writing source code in ...
If you have Docker installed, you might simply obtain a Docker container with a Python runtime and use that as the basis for a project. This is probably the best way to go if you eventually intend to deploy the app in question by way of Docker; you might as well get started on the...
