7 Putting it all together

Sooner or later, you’ll want to share your app with lots of people.
You have many options for doing this. Pop your code on PyPI, send out lots of emails, put
your code on a CD or USB, or simply install your app manually on the computers of those
people who need it. Sounds like a lot of work…not to mention boring. Also, what happens
when you produce the next best version of your code? What happens then? How do
you manage the update? Let’s face it: it’s such a pain that you’ll think up really creative
excuses not to. Luckily, you don’t have to do any of this: just create a webapp instead. And,
as this chapter demonstrates, using Python for web development is a breeze.
