Pyro is short for PYthon Remote Objects. It is an advanced and powerful Distributed Object Technology system written entirely in Python, that is designed to be very easy to use. Never worry about writing network communication code again, when using Pyro you just write your Python objects like you would normally. With only a few lines of extra code, Pyro takes care of the network communication between your objects once you split them over different machines on the network. All the gory socket programming details are taken care of, you just call a method on a remote object as if it were a local object!
Pyro provides an object-oriented form of RPC. You can use Pyro within a single system but also use it for IPC. For those that are familiar with Java, Pyro resembles Java's Remote Method Invocation (RMI). It is less similar to CORBA - which is a system- and language independent Distributed Object Technology and has much more to offer than Pyro or RMI. But Pyro is small, simple, fun and free!

Features of Pyro 3.x
To get an idea of how Pyro works, here is a scenario:
test' containing a class '
testclass', which will be accessed remotely.
testclass', and registers them with the Pyro Name Server.
testclass', the client can now invoke methods on the remote objects. The proxy will forward the method invocations and return the results, just as if it was the remote object itself. Not a single line of network communication code has been written.
To dive directly into the code, have a look at the various Pyro examples in the
Readme.txt). There is much to learn there. The easiest example to start with
is the "simple"
example, it shows how a normal python object is made into a Pyro object and accessed remotely from
pyro-xnsctool requires the Tkinter Python extension module, with Tcl/Tk installed.
pyro-wxnsctool requires the WxPython extension module with WxWindows.
