SPyDI Is a powerful engine to create distributed full text indexing systems and distributed search engines. It supports harvesting, crawling (pull mehtods), and push methods (via a Web interface or SPyRO Web services). It supports boolean and vector Information retrieval models. It has few dependencies, and comes with its own HTTP server and HTML embedded pages language (called pyew and wey pages), and session manager. It can use the SMTP of the Python library. It supports replacing the default modules with some better modules (Apache, exim, etc).
Conch is an SSHv2, Telnet, and VT102 implementation. It interfaces well with other Python projects such as Imagination, and includes an experimental console windowing library (Insults) and support for rudimentary line editing behaviors. A new implementation of Twisted's Manhole application is also included, featuring server-side input history and interactive syntax coloring.
Twisted Names is both a domain name server as well as a client resolver library. It comes with an "out of the box" nameserver that can read most BIND-syntax zone files as well as a simple Python-based configuration format. It can act as an authoritative server, perform zone transfers from a master to act as a secondary, act as a caching nameserver, or any combination of these. The client resolver library provides functions for querying all commonly used record types as well as a replacement for the blocking gethostbyname() function provided by the Python stdlib socket module.
Nevow is a Web application construction kit. It is designed to allow the programmer to express as much of the view logic as desired in Python, and includes a pure Python XML expression syntax, named stan, to facilitate this. It also provides rich support for designer-edited templates, using a very small XML attribute language to provide bi-directional template manipulation capability.
xmlrpcserver is a simple to use but fairly complete XML-RPC server module for Python, implemented on top of the standard module xmlrpclib. This module may, for example, be used in CGIs, inside application servers or within an application, or even standalone as an HTTP server waiting for XML-RPC requests. xmlrpcserver is completely written in Python and has no dependencies other than standard modules.
WebPython is a Web-application development toolkit written in the Python programming language. It contains an object relational database layer, portable over MySQL and PostgreSQL; a document templating engine complete with simple built-in automation; and a mechanism to store Python objects in an SQL database, among other features.
Peers is a distributed programming toolkit designed for building peer-to-peer systems. The toolkit is a hybrid language project which offers low level primitives for managing concurrency and communication. Using these primitives, complex P2P protocols and complete systems can be designed and implemented in Python, while maintaining high performance for critical operations.
