Consider the following code

def do_some_stuff(x)
  try:
    val = f(x)
  except NameError, e:
    val = False
  return va;

Deploying to GitHub Pages

You can serve your project websites for free on GitHub Pages. Normally, I use gulp to generate a minified and concatenated build inside the build/ directory, and then use git subtree to push only the build/ directory to the gh-pages branch (without needing to push the build to master).

First Push to GitHub Page

git subtree push --prefix build origin gh-pages
