There are a number of (very good) templating systems and languages available for Python. They fall in to one of two camps; either they are XML based, like Genshi, or they are text based, like Mako. Most programmers favour one or the other, but there is far from a consensus over which is better.
I'd like to use this debate to gather reasons for using one over the other in the context of web development. I suspect there will be no clear winner, but it should serve as a useful resource for those faced with the decision!
NB. You can post code with the [code] bbcode tag. Many languages are supported. e.g.
[code python]
print "Hello, World!"
[/code]
Python is text with a grammar. XML is also text with a grammar. Both have rules. The inevitable output for a web page is HTML. This is a third grammar, related to XML but more liberal.
If you believe that templates need to contain a significant amount of Python code, mixing these grammars become harder to understand. Rather mix two grammars (Python and HTML) in a single template than three.
According to Anthony Briggs:
If you've got a lot of code in your template, you're doing it wrong!
