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.

r/learnpython on Reddit: Generate python code from a generic template
February 7, 2023 -
Hi,
I need to write a console wizard that will ask several questions, and based on the answers and/or input, it will generate a py file.
For example:
$ python3 wizard.py
Name? IntelBP
Country? USA
Writing file ... Include.py generated.
$ cat include.py
name='IntelBP' country='USA'
... EOF.
So basically, what i need is a wizard engine that asks questions, and based on the answers, it reads a template (python code) and fills in some variables.
So there's essentially 2 aspects to this question:
What package can I use for writing the console interface? Ideally it will support text, lists, single, and multiple values for a specific wizard question.
Are there any packages designed to populate the values from the template into a python file? My greater concern is security related issues such as code injection.
Thanks!!

This sounds like an X-Y question, I think you should describe your larger goal rather than asking how to implement this specific solution. Generating code is usually a bad idea and usually not necessary.

It sounds like you should be generating config files or some other form of serialized data (env vars, json, csv or even just plain text) for a generic python script to reference.
Python Code Generation Tools
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

Create a template code based on existing code base
I have a use case where I need to create an initial draft python code based on existing corpus of code. I am thinking whether retrieval augmented generation will work in this case. Not sure if text embeddings will do a good job in similarity against code embeddings. More on community.openai.com

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.

Its requirements were: We needed to be able to perform interesting computation on the schema to create the code we needed. Cog would have to provide a powerful language to write the code generators in.
