What is the most pythonic way to build up large strings?
I am writing a couple of class methods to build up several lines of html. Some of the lines are conditional and most need variables inserted in them. Searching the web has given me a few ideas. Each has its pro's and cons. The best I have come up with is: def output_header_js(self, jquery=True, theme=None): if self.static_path is None : return None if jquery is True: output = '"

This method is going into a pyramid view class which will be rendered with chameleon or any other template engine. Actually it is going into a base class to be inherited into a view class. The idea is to setup all the parameters for the HTML when the view class is created and reuse all that info for the initial page as well as all the ajax calls. I didn't realize I could use formatting with triple quoted strings. I will look into that. -- https://mail.python.org/mailman/listinfo/python-list

Is there anyway efficiently build large strings with lots of conditional inclusions, repetative sections built dynamically by looping (see the field section above)etc. Is there a mutable string class? -- https://mail.python.org/mailman/listinfo/python-list

Each section can be conditionally built up with variable insertions as required. This should be more efficient and will scale nicely as required. -- https://mail.python.org/mailman/listinfo/python-list
