Whats the best way to generate java from python? I want to write a decorator that generates java code to call a json version of a function (I can use existing decorators to export the json api). ... More on stackoverflow.com

I'd probably use metaclasses if I had the kind of problem where code generation could actually help. The last time I saw a project using code generation where I thought that it ought have to used metaclasses was a tool to generate python code from swagger descriptions. Django's ORM is a good example where metaclasses were used to good effect (there are very few of those). In general I'm extremely suspicious of anybody who claims to have the kind of problem that requires either metaclasses or code generation would help though. It is suitable only for problems that are very, very, very abstract (e.g. like an ORM or REST API interaction framework). In 90% of cases I've seen the person attempting to use it vastly overgeneralized the problem that they actually had in an attempt to prepare for future problems never arose. In the process of doing that they then created a code clusterfuck that was hellishly hard to understand and debug (and in some cases I was left to clean up the mess). It wasn't simple and it can't, intrinsically, ever be simple (there is some language theory behind this). I could be convinced otherwise by describing your problem, but right now I'm 80% convinced that what you have described is an XY problem and that you're attempting to do this because you overgeneralized your problem. If you describe the actual problem you're solving it might help. More on reddit.com

To be honest, me, a C/C++ developer once had issues with grasping even such basic concept as pointers. You learnt Python and you enjoy it. That's good. You already have one language in your portfolio. Regarding OOP - if you use classes in Python it is already a part of OOP. (Of course, you need to be able to use e.g. inheritance in Python) You want to code in English, so you prefer something with easy syntax, so maybe JS? Regarding JVM - you should not care about it until you are senior-ish dev. Java philosophy is "run everywhere". If you screw up you JVM, it will just run slower and eat your RAM. ----- OK, I wrote a lot text, so let's summarize: Not being able to write a linked is not a big deal for a beginner You really must understand OOP. Without it you won't get your first job. You can do learn it in Python Btw, Python is not that great as the sole language, market-wise. More on reddit.com

I've used JPype for a while. It also starts a JVM from python. Once set up, interoperating with Java is transparent. You can start the JVM in such a way that it can be debugged directly using remote debugging tools. More on reddit.com
