<p>This is a Python decorator which helps implementing an aspect oriented implementation of a <em>retrying</em> of certain steps which might fail sometimes. A typical example for this would be communication processes with the outside world, e. g. HTTP requests, allocation of some resource, etc. To use it, refactor the step in question into a (local) function and decorate this with the <code>retry</code> decorator. See examples in the discussion sector below.</p>

<p>Sometimes we want a function to be able to be retried automatically, such as a function that does networking trying to write/read data through a pre-established connection. Instead of writing try/except everywhere, a decorator would save much code and provide a single copy of code to do all the work.</p>
