Network Programming

While most programming is done with local resources in mind (i.e., your computer), Python is more than able to pull data from the furthest reaches of the globe for whatever purpose you deem necessary. It does this via network protocols. These pages address how your Python program can communicate over a network using protocols such as SOAP and TCP/IP as well as platforms such as Zope and Plone.

Network Protocols That Python Can Speak
While most programming is done with local resources in mind (i.e., your computer), Python is more than able to pull data from the furthest reaches of the globe for whatever purpose you deem necessary. It does this via network protocols. A protocol is simply a set format for exchanging information. These pages address how your Python program can communicate over a network using protocols such as SOAP and TCP/IP as well as platforms such as Zope and Plone.
