Building concurrent applications with Tornado Future

Tornado Future construct allows us to develop non-blocking and asynchronous calls in a more efficient way. In this recipe, we will develop a simple asynchronous application based on Tornado Future constructs.

Getting ready

Tornado is a web framework. In order to execute this recipe, first you need to install Tornado in your computer, which can be done by using the following command in Linux environments:

$ sudo pip install tornado

How to do it...

We will build a concurrent application to illustrate the functionality of Tornado. In this example, the tornado.concurrent module of Tornado has been used.

Listing 4.13 explains the code for a simple concurrent application using Tornado:
