I personally just use the standard Python "reload" function on my
major web modules, then when I hit ctrl-R in my browser it loads the
latest Python code and re-renders the current page using it. The
major downside with this approach is that you must structure your
Python code in a way that works with reload. The other potential
gotcha is that reload is really slow and you don't want it in
production code, so I always wrap mine with "if __debug__".
