Cog: A Code Generation Tool Written in Python
For each chunk of generator code it finds, Cog will: ... In a word, great. We now have a powerful tool that lets us maintain a single XML file that describes our data schema. Developers changing the schema have a simple tool to run that generates code from the schema, producing output code in four different languages across 50 files.

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.

August 11, 2022 - In the first part, we synthesize the bytecode and line number tables, by the most direct fashion possible — writing to a BytesIO object, and getting the requisite binary opcode values out of the dis library. In the second part, we do the interfacing to turn byte code into something Python can invoke, by constructing a CodeType object (Python’s internal representation of a code object) and a FunctionType object out of that.

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).
