The py_interface is a python-implementation of an Erlang node. For information on the Erlang programming language, visit the web site http://www.erlang.org/.

The py_interface provides the possibility to create a node that may be used for communication with other Erlang nodes.

Some characteristics:

• The Python nodes are hidden, like the Java nodes
• The Python node translates Erlang types to Python types as far as there is a reasonable Python counterpart. If there is not, then a class is used.
• The Python node is a single threaded callback-driven process.
• The Python node is released under LGPL.

General programming model: When using the py_interface, the general principle is to register a callback for different purposes, such as incoming messages to the pid, an return from an rpc-call, or a timeout. The callback will get called whenever the message or return value arrives or when the timer times out.
