An alternative approach.

Since you have a combination of HTML and Python code, I would suggest to separate the logical part and the part of the presentation , switching to the usual template engine .

An example of using mako .

Create an HTML template file, leaving the appropriate placeholders:

 <html> <head> <title>${title}</title> </head> <body> <p>${text}</p> </body> </html>

Then, in python code, render the template containing the values ​​for placehodlers:

 from mako.template import Template t = Template(filename='index.html') print t.render(title='My Title', text='My Text')

This will print:

 <html> <head> <title>My Title</title> </head> <body> <p>My Text</p> </body> </html>

Just use double curly braces to avoid them.

like

 a1 = """div.test{{ bla; }}"""

You can use templates, as Alex said, or use formatting with a dictionary

 a1 = '<html><title>%(title)s</title><body>%(body)s</body></html>' vars = {'title': 'test', 'body': 'test'} output = a1 % vars
