Exercises, examples and other material relating to training module Y303. This module is presented on Private Courses and Specially Run Courses only

Python supports many network protocols through libraries such as urllib and urllib2, and you can also write network programs direct using TCP or UDP sockets. Associated subjects such as forking, testing read buffers, pipes and more are also included here.

4087	Python network programming - new FTP and socket level examples These days, it's the exception rather than the rule to write low level network code within your applications - and during today's Intermediate Python course, I wrote an example showing an FTP connection to retrieve data using ftplib. The first example is [here] - grabbing a file, saving it locally via ...	2013-05-18
2765	Running operating system commands from your Python program As from Python 2.6, os.popen and friends are deprecated methods and you should use the subprocess module for subprocesses. So that's the way to go if you want to run operating system commands. New example showing this - [here] Starting with: from subprocess import * I can run a process and allow ...	2010-05-15
2695	TCP v UDP / Client v Server - Python examples Python's socket module makes it easy for you to write your own clients and server ... and yesterday I produced "Hello World" style examples of each on the final day of our Python Programming Course. I'm going to share these examples with you here ... but I'm also going to add a word of caution first ...	2010-03-26
2694	Multiple processes (forking) in Python What is forking If you want a process to head off in two different directions, you can fork it. That results in identical copies of the process being created - the original (parent) and the copy (child), each with their own complete set of variables, and program counter, etc. The clever thing is that ...	2010-03-25
2368	Python - fresh examples of all the fundamentals Some more new examples in Python - from this week's course. From my Introduction to Python / simple example to show the power of the language, I present my example that parsed a big data (log) file and counter and sorted by number of accesses the hits from various remote hosts. A long report, ending ...	2009-08-23 (longer)
2365	Counting Words in Python via the web I love writing things in Python - it's a great language for achieving a great deal in a short time. And it works well got Simple CGI scripts. Today's challenge - to count the number of words (and number of DIFFERENT words) in a piece of text, so give an idea of how much work would be involved in translating ...	2009-08-19
