python workshop,, by User:Fs111
def workshop(python_at_hsb)
HSB Brussels,Belgium
5 EUR (for non-members)


This will be a beginners workshop, things I (fs111) want to cover:

  • Brief introduction in the who, what and where in python
  • Hello World and the interactive interpreter
  • control structures
  • built-in types (numbers, strings, lists, dicts, sets etc.) and higher level functions
  • input/output
  • module system (imports)
  • objects and classes and types
  • documentation system
  • neat little tricks and features you should know (generators, list comprehension, slicing)
  • some modules from the standard lib that you should know (OS interface, filesystem, option parsing, xml?, network stuff etc.)
  • Q/A all the time of course
  • free style hacking afterwards
  • Python egg
  • Paster

How long will the workshop last?[edit]

I really don't know. I try to cover the stuff mentioned above and then we can go into freestyle hacking, where we help each other out I guess. As long we do not run out of mate we can go on :-)

Stuff you need[edit]

I will use the latest release of the Python 2.x series which is 2.6 right now. 3.x is out already for some time but the adoption is low and a big number of 3rdd party modules are not ported yet. So what I would expect from you is that you have the following installed:

  • python 2.6, which can be downloaded here
  • a text editor of choice, anything will do, I use vim. Tips for vim and Python here.
  • a shell

# Add auto-completion and a stored history file of commands to your Python
# interactive interpreter. Requires Python 2.0+, readline. Autocomplete is
# bound to the Esc key by default (you can change it - see readline docs).
# Store the file in ~/.pystartup, and set an environment variable to point
# to it:  "export PYTHONSTARTUP=/home/user/.pystartup" in bash.
# Note that PYTHONSTARTUP does *not* expand "~", so you have to put in the
# full path to your home directory.

import atexit
import os
import readline
import rlcompleter
readline.parse_and_bind('tab: complete')
historyPath = os.path.expanduser("~/.pyhistory")

def save_history(historyPath=historyPath):
    import readline

if os.path.exists(historyPath):

del os, atexit, readline, rlcompleter, save_history, historyPath

Hello World[edit]

#!/usr/bin/env python
# -*- coding: utf-8 -*-

print "Hello HSB"

spawning processes[edit]

 import subprocess

don't try popen, os.system, or whatever else


Here is the pdf of the quick introduction from the beginning of the workshop:
