Python format throws KeyError

Question

The following code snippet:

template = \"\\                                                                                
function routes(app, model){\\            


        

Answer 1

Well, just another way of doing this without format could be:

In [1673]: className = 'myclass'                                                                                                                                                                            

In [1674]: template = 'function routes(app, model){app.get("/preNew"{'+className+'}, function(req, res){res.render({"'+className+'".ejs, {});});});'                                                        

In [1675]: template                                                                                                                                                                                         
Out[1675]: 'function routes(app, model){app.get("/preNew"{myclass}, function(req, res){res.render({"myclass".ejs, {});});});'
