I have problems typing a lot of underscores because it's uncomfortable for my wrists and it risks a repetitive strain injury over time.
I would prefer to use Java-style camelcase everywhere - it's more ergonomic. Unfortunately the vast majority of Python libraries use underscores.
So I would like a tool or an IDE that auto-translates between camel case and underscores (sometimes called "snake case"). The tool has to be able to auto-convert references to objects of a given type (for example, a command could be: "Convert all function arguments from snake case to camel case" or "Convert all variables from camel case to snake case").
I'd prefer an IDE or a GUI tool, however command line tools are also acceptable. The best solution would be an IDE where I can set what types of objects should be camel case or snake case, type in either case, and have the IDE automatically recognize them in real-time and fix them.
