Tcl, Awk, Bash, Shell Training in Annapolis, Maryland

This section of our beginning python training class always stumps students. Firstly, because they need to know the difference between a function and a method. Secondly, they need to understand object oriented programming concepts. Thirdly, they need to realize that python has three types of methods. Then they need to know how to use each method, which means they need to know the purpose of each method type. Then they have to understand mutable versus non-mutable types. The list goes on. As part of our python tutorial, I hope to shed some light on this confusing topic.

To begin, the difference between a function and a method in python is that a method is defined within a class. Here is an illustration:

#function

	def greeting():
	                print "Hello, I hope you're having a great day!"

	class HSGPrinter(object):
	                #method
	                def greeting(self): 
	                                print "Hello, I hope you're having a great day!"

As should be obvious, the second definition of greeting is encapsulated within the HSGPrinter class and is , therefore, refered to as a method.

The astute reader will notice that the greeting method contains one parameter named self. For those who know C++ , Java or C#, self is equivalent to this i.e. it is a reference to the invoking object:

Working With Lists In Python

The importance of variables in any programming language can’t be emphasised enough. Even if you are a novice, the chances are good that you will have been using variables for quite a while now.

They are the cornerstone of any language and without them we would not be able to accomplish much of anything. However, most of you up until this point have probably only been working with standard variables, variables which can hold single values such as an integer, a single character, or a string of text.

In this tutorial we are going to take a look at a more special type of variable called an array. Arrays can seem quite daunting at first glance but once you get used to working with them you will wonder how you ever managed to program without them.

The reason arrays are special is because they can hold more than one value. Think about this: say you create a variable which contains a line of text like the code below:

Checking to see if a directory exists and then creating it if it is not present requires a few lines of code. Isn't Python great. Begin by importing the os module and use the exists and makedirs functions.

import os

if os.path.exists(somedirectory):
   os.makedirs(somedirectory)
