Best Python templating library to facilitate code generation [closed]
Best suggestion: try them all. It won't take long.
My favourite: Jinja2 (by a mile)
It has decent syntax, can trace errors through it, and is sandboxable.
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.
The most important concern is whether you can live with the syntax the templates require. Second and third (depending on your application needs) would be speed and ease of distribution.
I looked at all of them, but the only syntax I could stand was Jinja. Jinja has the advantage of supporting a lot of Python constructs, so it's very easy to add snippets of functionality to the templates as needed, without coding special tags. Most of what requires tags in other template systems is handled by macros in Jinja.
Of course, if you're looking for something easy and quick, it's hard to beat the Python templating API in the core language.
