My favourite: Jinja2 (by a mile)

r/Python on Reddit: Python Code Generation Tools
March 9, 2019 -
What do you guys use to generate Python code? I saw that a lot of people just use Jinja2 with some templates, which looks simple and powerful. You still have to generate the environments and write the templates. Now I'm looking around whether someone already did the work of generalizing that step (thinking about fields in classes, inheritance, constructors etc. and how to map that data to the environment) or whether I have to do it myself.
TLDR: Are there simple but powerful Python code generation "frameworks"?
EDIT:
-
I found pymultigen. Seems like it helps with creating code in multiple files.
-
Looks like pyecoregen is a specialized multi-file code generator based on pymultigen.

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.

If you're looking for some codegen support stuffs in python, I'd give you some info Python std module ast AST to python source code emitter, unparse. https://github.com/python/cpython/blob/master/Tools/parser/unparse.py AST based scoping analyzer, https://github.com/thautwarm/scoping-resolver

If you're doing code generation, you might find Cog useful - it's specifically for code generation, rather than being a generally applicable templating language.
code generation - Are there any libraries for generating Python source? - Stack Overflow
I'd like to write a code generation ... generated classes. I can create the class and use it in code, but it would be nice to have a sourcefile both for documentation and to allow something to import. Does such a thing exist? I've seen sourcecodegen, but I'd rather avoid messing with the ast trees as they're not portable. ... I'm not aware of any off-the-shelf library, but have a look at the Python templating ...

This is pretty much the best way to generate Python source code. However, you can also generate Python executable code at runtime using the ast library. You can build code using the abstract syntax tree, then pass it to compile() to compile it into executable code. More on stackoverflow.com
Will devs be replaced by AI? I found this ai python code generator and it's terrifyingly good
Sooner than later there will be an indirect code leak where someone will train one of such public models on their non-public code... And if the model won't be trained it will not give matching results... or if it will be trained and run in-house it will require the hardware and the specialist to do so which isn't free or cheap. Simpler stuff like setup an application or module will work, but when you tell it to generate a scaffold for specific API provider or module it was never trained on it will generate rubbish assuming it is the same as APIs/modules it was trained on. Not to mention that even if the code gets generated it has to be tested, it has to be integrated properly and so on. But wannabies, 50-subscriber YouTubers that still produce "Python string for beginners 2023" have yet another reason to be afraid they will never get an actual job. More on reddit.com

The fault in code generation is simply the feeble-minded-ness of ChatGPT as of late. It will screw up code again you had just made it fix. You must pretty much limit yourself to just making small functions it can understand.

We use Jinja2 to fill in a template. It's much simpler.
The template looks a lot like Python code with a few {{something}} replacements in it.

This is pretty much the best way to generate Python source code. However, you can also generate Python executable code at runtime using the ast library. You can build code using the abstract syntax tree, then pass it to compile() to compile it into executable code. Then you can use eval() to run the code.
I'm not sure whether there is a convenient way to save the compiled code for use later though (ie. in a .pyc file).
