I know there are libraries for python to print html.

How do they do the template iteration.

I'm probably gonna look at their code eventually.

Just wonderin if any dream in code people had any knowledge to start me out.

Some more specific questions.

Are the methods really complicated to do arbitrary iteration with python to produce html templates with content?

Are there already some python functions that could help with arbitrary iteration like this.

I'm thinking any list type input with any amount of lists.

A simple way to start would be to use regular expressions in conjunction with eval.

I had already considered this, but I thought they must be using something else because of the whole idea that using eval should be discouraged.

Eval is discouraged; it is dangerous when user input is fed to eval, and it needs to be compiled at runtime as it is encountered.

However, if you wanted to build a sufficiently powerful templating system without eval, you could use getattr() or dictionary indexes to evaluate variables.

I suppose it would be ok to use eval() if the template was only producing output.

Other safer methods could be used to accept user input.
